1.2 ST overview
This document contains the Security Target for MRTD chips based on the EAC application of the cv act
ePassslet Suite. The cv act ePasslet Suite is a set of Javacard applications intended to be used exclusively on
the NXP JCOP Javacard OS platforms, which are certified according to CC EAL 5+ [ZertJCOP]. The cv act
ePasslet Suite as well as the NXP JCOP operating system are provided within the ROM mask of a smart card
chip based on the NXP P5CD security controller, which is itself certified according to CC EAL 5+ [ZertIC], and
certified cryptographic library [ZertCL].
This security target claims strict conformance to the Protection Profile Machine Readable Travel Document
with “ICAO Application”, Extended Access Control (BSI-CC-PP0056) [PP0056].
The main objectives of this ST are:

to introduce TOE and the MRTD application,

to define the scope of the TOE and its security features,

to describe the security environment of the TOE, including the assets to be protected and the
threats to be countered by the TOE and its environment during the product development, production and usage.
The cv act ePasslet Suite v2.1 is produced on one specific hardware (P5Cx145V0v, cf. [ZertIC]) that differs
only with respect to the memory, interface configuration and the additional biometry provider (not used by
the TOE and with non-interfering security functionality). The two different possible biometry providers lead
to the two different ROM identification values.

sent at the same time by instantiating multiple applets with their distinct configurations with some restrictions detailed below. A common combination could be an ICAO MRTD applet and an ePKI applet providing a travel application with LDS data and EAC authentication together with a signature application.
The following configurations are certified according to Common Criteria:

configuration providing Machine Readable Travel Document with „ICAO Application”, Basic Access
Control (BAC),
 configuration providing Machine Readable Travel Document with „ICAO Application”, Extended
Access Control (EAC),
 configuration providing Machine Readable Travel Document with „ICAO Application”, Extended
Access Control with PACE,
 configuration providing Secure Signature Creation Device with key generation.
Combinations of certified and non-certified applications are possible.
Via configuration the instanciated applets can be tied to the contactless and/or the contact interface, respectively.
1.3.2 TOE definition
The Target of Evaluation (TOE) is the contactless integrated circuit chip containing components for a
machine readable travel document (MRTD chip). After instantiation and configuration of the
ePasslet2.1/MRTD-EACv1-BAC configuration it can be programmed according to the Logical Data Structure
(LDS) [ICAODoc] and providing the Basic Access Control and the Extended Access Control according to the
ICAO document [ICAODoc] and the technical report [TR-03110].
The TOE consists of

the circuitry of the MRTD’s chip (the integrated circuit, IC) including the contact-based interface2
with hardware for the contactless interface including contacts for the antenna,

the platform with the Java Card operation system JCOP 2.4.2 R3 by NXP, in the variants
o
J3E120_M65,
o
J3E082_M65,
o
J2E120_M65, and
o
J2E082_M65.

cv act ePasslet Suite v2.1 – Java Card applet configuration providing Machine Readable Travel Document with „ICAO Application”, Extended Access Control,

the associated guidance documentation Administrator and User Guidance [Guidance].
The TOE’s functionality claimed by this Security Target is realized by the cv act ePasslet Suite in the MRTDEACv1-BAC configuration only.
Some of the underlying platform variants of this composite TOE provide MIFARE functionality; please note
that this functionality is out of scope of the TOE’s security functionality claimed by this Security Target.
Please note that the MRTD’s chip itself (the integrated circuit, IC) is also equipped with a contact-based
interface. ‘ePasslet Suite v2.1 – Java Card applet configuration providing Machine Readable Travel Document with „ICAO Application”, Extended Access Control’, is the only application that has access to the contactless interface.

1.3.3 TOE usage and security features for operational use
This paragraph is directly based on the corresponding paragraph in the protection profile [PP0056].
A state or organisation issues a MRTD to be used by the holder for international travel. The traveller presents a MRTD to the inspection system to prove his or her identity.
The MRTD in context of this security target contains (i) visual (eye readable) biographical data and portrait
of the holder, (ii) a separate data summary (MRZ data) for visual and machine reading using OCR methods
in the Machine readable zone (MRZ) and (iii) data elements on the MRTD’s chip according to LDS for contactless machine reading. The authentication of the traveller is based on (i) the possession of a valid MRTD
personalized for a holder with the claimed identity as given on the biographical data page and (ii) biometrics
using the reference data stored in the MRTD.
The issuing state or organization ensures the authenticity of the data of genuine MRTD’s. The receiving state
trusts a genuine MRTD of an issuing state or organization.
Within this security target the MRTD is viewed as a unit of

the physical MRTD as travel document in form of paper, plastic and chip. It presents visual readable
data including (but not limited to) personal data of the MRTD holder:
(1) the biographical data on the biographical data page of the passport book,
(2) the printed data in the Machine-Readable Zone (MRZ) and
(3) the printed portrait.

the logical MRTD as data of the MRTD holder stored according to the Logical Data Structure [ICAODoc] as specified by ICAO on the contactless integrated circuit. Via the contactless interface of the
integrated circuit, the following data including (but not limited to) personal data of the MRTD holder
are accessible:
(1) the digital Machine Readable Zone Data (digital MRZ data, EF.DG1),
(2) the digitized portraits (EF.DG2),
(3) the biometric reference data of finger(s) (EF.DG3) or iris image(s) (EF.DG4) or both2
(4) the other data according to LDS (EF.DG5 to EF.DG16) and
(5) the document security object.
The issuing State or Organization implements security features of the MRTD to maintain the authenticity
and integrity of the MRTD and their data. The MRTD as the passport book and the MRTD’s chip is uniquely
identified by the document number.
The physical MRTD is protected by physical security measures (e.g. watermark on paper, security printing),
logical (e.g. authentication keys of the MRTD’s chip) and organisational security measures (e.g. control of
materials, personalization procedures). These security measures include the binding of the MRTD’s chip to
the passport book.
The logical MRTD is protected in authenticity and integrity by a digital signature created by the document
signer acting for the issuing State or Organization and the security features of the MRTD’s chip.
The ICAO defines the baseline security methods Passive Authentication and the optional advanced security
methods Basic Access Control to the logical MRTD, Active Authentication of the MRTD’s chip, Extended
Access Control to and the Data Encryption of additional biometrics as optional security measure in the ICAO
Technical Report [ICAODoc]. The Passive Authentication Mechanism and the Data Encryption are performed
completely and independently of the TOE by the TOE environment.
This security target addresses the protection of the logical MRTD (i) in integrity by write-only-once access
control and by physical means, and (ii) in confidentiality by the Basic Access Control Mechanism and the
Extended Access Control Mechanism. This security target addresses the Chip Authentication described in
[TR-03110] as an alternative to the Active Authentication stated in [ICAODoc].
7 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
The confidentiality by Basic Access Control is a mandatory security feature that shall be implemented by
the TOE, too. Nevertheless this is not explicitly covered by this security target as there are known weaknesses in the quality (i.e. entropy) of the BAC keys generated by the environment. Therefore, the MRTD has
additionally to fulfill the ‘Common Criteria Protection Profile Machine Readable Travel Document with
„ICAO Application", Basic Access Control’ [PP0055]. Due to the fact that [PP0055] does only consider extended basic attack potential to the Basic Access Control Mechanism (i.e. AVA_VAN.3) the MRTD has to be
evaluated and certified separately. The evaluation and certification process will be carried out simultaneously to the current process according to the security target in hand.
PP application note 1: As explained in the protection profile [PP0056] there is a separate Security Target
for BAC [ST_BAC].
For BAC, the inspection system (i) reads optically the MRTD, (ii) authenticates itself as inspection system by
means of Document Basic Access Keys. After successful authentication of the inspection system the MRTD’s
chip provides read access to the logical MRTD by means of private communication (secure messaging) with
this inspection system [ICAODoc], normative appendix 5.
The security target requires the TOE to implement the Chip Authentication defined in [TR-03110]. The protocol provides evidence of the MRTD’s chip authenticity and prevents data traces described in [ICAODoc],
Annex G, section G.3.3. The Chip Authentication is provided by the following steps: (i) the inspection system
communicates by means of secure messaging established by Basic Access Control, (ii) the inspection system
reads and verifies by means of the Passive Authentication the authenticity of the MRTD’s Chip Authentication Public Key using the Document Security Object, (iii) the inspection system generates a ephemeral key
pair, (iv) the TOE and the inspection system agree on two session keys for secure messaging in ENC_MAC
mode according to the Diffie-Hellman Primitive and (v) the inspection system verifies by means of received
message authentication codes whether the MRTD’s chip was able or not to run this protocol properly (i.e.
it could apply the Chip Authentication Private Key corresponding to the Chip Authentication Public Key for
derivation of the session keys). The Chip Authentication requires collaboration of the TOE and the TOE environment.
The security target requires the TOE to implement the Extended Access Control as defined in [TR-03110].
The Extended Access Control consists of two parts (i) a Terminal Authentication Protocol to authenticate
the inspection system as entity authorized by the Issuing State or Organization through the receiving State,
and (ii) an access control by the TOE to allow reading the sensitive biometric reference data only to successfully authenticated authorized inspection systems. It requires the Chip Authentication of the MRTD’s chip
to the inspection system and uses the secure messaging established by the Chip Authentication Mechanism
to protect the confidentiality and integrity of the sensitive biometric reference data during their transmission from the TOE to the inspection system. The issuing State or Organization authorizes the receiving State
by means of certification the authentication public keys of Document Verifiers who create Inspection System Certificates.
1.3.4 Major security features of the TOE
The TOE provides the following TOE security functionalities:

TSF_Access manages the access to objects (files, directories, data and secrets) stored in the applet’s
file system. It also controls write access of initialization, pre-personalization and personalization
data.

TSF_Admin manages the storage of manufacturing data, pre-personalization data and personalization data.

TSF_Secret ensures secure management of secrets such as cryptographic keys. This covers secure
key storage, access to keys as well as secure key deletion. These mechanisms are mainly provided
by TSF_OS.

cv act ePasslet2.1/MRTD-EACv1-BAC Security Target

TSF_Crypto performs high level cryptographic operations. The implementation is mainly based on
the Security Functionalities provided by TSF_OS. The supported crypto mechanisms are:
o
the Diffie-Hellman key derivation Protocol with cryptographic key sizes between 1976 and
2048 bit, and ECDH compliant to ISO 15946 with cryptographic key sizes of 256 and 320 bit
with specified elliptic curves,
o
digital signature verification in accordance with ECDSA and cryptographic key sizes of 160,
192, 224, 256 and 320 bit (with defined domain parameters),
o
Terminal Authentication Protocol, Secure messaging in MAC-ENC mode, and Symmetric Authentication Mechanism based on AES.
o
Active Authentication with RSA and with cryptographic key sizes between 1976 and 2048
bit.

TSF_SecureMessaging realizes a secure communication channel with MACs and encryption based
on AES (128, 192 and 256 bit key length).

TSF_Auth realizes different authentication mechanisms: TSF_Auth_Term (Terminal Authentication),
TSF_Auth_Sym used for BAC and symmetric authentication based on pre-shared keys used for personalization, TSF_Auth_Chip to manage the capability of the TOE to authenticate itself to the terminal using the Chip Authentication Protocol (EAC) and the optional TSF_Auth_AA for Active Authentication.

TSF_Integrity protects the integrity of internal applet data like the Access control lists.

TSF_OS contains all security functionalities provided by the certified platform (IC, crypto library,
Javacard operation system). Besides some minor additions, the cryptographic operations are provided by this platform.
1.3.5
TOE life cycle
The TOE life cycle is described in terms of the four life cycle phases. This paragraph is directly based on the
corresponding paragraph in the protection profile [PP0056].
1.3.5.1
Phase 1: Development
(Step 1) The TOE is developed in phase 1. The IC developer develops the integrated circuit, the IC Dedicated
Software and the guidance documentation associated with these TOE components.
(Step 2) The software developer3 uses the guidance documentation for the integrated circuit and the guidance documentation for relevant parts of the IC Dedicated Software and develops the IC Embedded Software (operating system), the MRTD application and the guidance documentation associated with these TOE
components.
The manufacturing documentation of the IC including the IC Dedicated Software and the Embedded Software in the non-volatile non-programmable memories (ROM) is securely delivered to the IC manufacturer.
The IC Embedded Software in the nonvolatile programmable memories, the MRTD application, the initialisation data and the guidance documentation is securely delivered to the MRTD manufacturer.
1.3.5.2
Phase 2: Manufacturing
(Step 3) In a first step the TOE integrated circuit is produced containing the MRTD’s chip Dedicated Software
and the parts of the MRTD’s chip Embedded Software in the nonvolatile non-programmable memories
Please note that in this ST the role software developer of the protection profile is subdivided into two
separate roles: the operating system is developed by the OS software developer, and the MRTD application
by the (MRTD) software developer.
3

cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
(ROM). The IC manufacturer writes the IC Identification Data onto the chip to control the IC as MRTD material during the IC manufacturing and the delivery process to the MRTD manufacturer. The IC is securely
delivered from the IC manufacturer to the MRTD manufacturer.
The TOE delivery according to CC is the delivery of the IC (with the application code in ROM) from the IC
manufacturer to the MRTD manufacturer.
If necessary the IC manufacturer adds the parts of the IC Embedded Software in the non-volatile programmable memories (for instance EEPROM).
(Step 4) The MRTD manufacturer combines the IC with hardware for the contactless interface in the passport book.
(Step 5) The MRTD manufacturer (i) creates the MRTD application and (ii) equips MRTD’s chips with prepersonalization Data.
PP application note 2: Creation of the application implies applet instantiation.
In this step the final (but not yet personalized) MRTD is generated from the certified components according to the binding initialization and pre-personalization guidelines provided in [Guidance].
The pre-personalized MRTD together with the IC Identifier is securely delivered from the MRTD manufacturer to the Personalization Agent. The MRTD manufacturer also provides the relevant parts of the guidance
documentation to the Personalization Agent.
1.3.5.3
Phase 3: Personalisation of the MRTD
(Step 6) The personalization of the MRTD includes (i) the survey of the MRTD holder biographical data, (ii)
the enrolment of the MRTD holder biometric reference data (i.e. the digitized portraits and the optional
biometric reference data), (iii) the printing of the visual readable data onto the physical MRTD and their
secure transfer to the personalisation agent, (iv) the writing of the TOE User Data and TSF Data into the
logical MRTD and (v) the writing the TSF Data into the logical MRTD and configuration of the TSF if necessary.
The step (iv) is performed by the Personalisation Agent and includes but is not limited to the creation of (i)
the digital MRZ data (DG1), (ii) the digitised portrait (DG2), and (iii) the Document security object.
The signing of the Document security object by the Document signer [ICAODoc] finalizes the personalization
of the genuine MRTD for the MRTD holder. The personalized MRTD (together with appropriate guidance
for TOE use if necessary) is handed over to the MRTD holder for operational use.
PP application note 3: <Information only – no action required>
PP application note 4: As in the PP this ST distinguishes between the roles „personalization agent“ and
„doument signer“
1.3.5.4
Phase 4: Operational use
(Step 7) The TOE is used as MRTD’s chip by the traveller and the inspection systems in the “Operational
Use” phase. The user data can be read according to the security policy of the Issuing State or Organization
and used according to the security policy of the Issuing State but they can never be modified.
PP application note 5: The authorized Personalization Agents might be allowed to add (not to modify) data
in the other data groups of the MRTD application (e.g. person(s) to notify EF.DG16) in the Phase 4 “Operational Use”. This will imply an update of the Document Security Object including the re-signing by the Document Signer.
PP application note 6: The intention of the underlying PP [PP0056] is to consider at least the phases 1 and
parts of phase 2 (i.e. Step1 to Step3) as part of the evaluation and therefore to define the TOE delivery
according to CC after this phase. Since specific production steps of phase 2 are of minor security relevance
(e. g. booklet manufacturing and antenna integration) these are not part of the CC evaluation under ALC.
Nevertheless the decision about this has to be taken by the certification body resp. the national body of the
issuing State or Organization. In this case the national body of the issuing State or Organization is responsible for these specific production steps.
10 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
Note that the personalization process and its environment may depend on specific security needs of an
issuing State or Organization. All production, generation and installation procedures after TOE delivery up
to the “Operational Use” (phase 4) have to be considered in the product evaluation process under AGD
assurance class.
Remark: This ST considers only phase 1 and parts of phase 2 (steps 1 - 3) as part of CC evaluation under ALC.
1.3.6 Non-TOE hardware/software/firmware required by the TOE
There is no explicit non-TOE hardware, software or firmware required by the TOE to perform its claimed
security features. The TOE is defined to comprise the chip and the complete operating system and application. Note, the inlay holding the chip as well as the antenna and the booklet (holding the printed MRZ) are
needed to represent a complete MRTD, nevertheless these parts are not inevitable for the secure operation
of the TOE.

2.2.5 Assessment of Platform Organisational Security Policies
The platform ST contains the Organisational Security Policy “OSP.PROCESS-TOE” referring to accurate identification of each TOE instance. This policy will be fulfilled by a distinct product code for the platform and
for the composite TOE each. This policy does not contradict to the policies of this ST. The other Organisational Security Policy “OSP.VERIFICATION” focuses on the integrity of loaded applets, which is fulfilled by
the TOE of this ST since the applet is loaded from ROM only.

Assessment of Platform Assumptions
In the first column, the following table lists all significant assumptions of the Platform ST. The last column
provides an explanation of relevance for the Composite TOE.
22 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
Significant Platform Assumption Relevance for Composite ST
A.APPLET
A.APPLET states that applets loaded post-issuance do not contain native methods. This assumption leads to appropriate directives in the
user guidance [Guidance].
A.VERIFICATION
This assumption targets the applet code verification. In the context of
this ST the applet is loaded from ROM only and was verified before
ROM mask production. Regarding post-issuance loading of third party
applets, this assumption leads to appropriate directives in the user
guidance [Guidance].
A.USE_DIAG
A.USE_DIAG is required in the Platform ST to cover secure communication during packaging, finishing and personalisation. This is corresponding to OT.Data_Int of this composite ST.
A.USE_KEYS
During Operational use, this assumption icorresponds to A.Insp-Sys.
Regarding the packaging, finishing and personalisation phase, this assumption is corresponding to A.MRTD_Manufact and A.Pers_Agent of
this ST. There are no contradictions in the assumptions.
23 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
A.PPROCESS-SEC-IC
This assumption focuses on the security of the production process after chip delivery; this is also targeted by A.MRTD_Manufact,
A.MRTD_Delivery and A.Pers_Agent of this ST.
A.PPROCESS-SEC-IC of the platform ST states that it is assumed that
security procedures are used after delivery of the TOE by the TOE
Manufacturer up to delivery to the end consumer to maintain confidentiality and integrity of the TOE and of its manufacturing and test
data (to prevent any possible copy, modification, retention, theft or
unauthorised use). This means that the Phases after TOE Delivery are
assumed to be protected appropriately. The assets to be protected
are:
- the Security IC Embedded Software including specifications, implementation and related documentation,
- pre-personalisation and personalisation data including specifications
of formats and memory areas, test related data,
- the User Data and related documentation, and
- material for software development support
as long as they are not under the control of the TOE Manufacturer.
Within this ST, it is assumed that

A.MRTD_Manufact: Appropriate functionality testing of the
MRTD is used. It is assumed that security procedures are used
during all manufacturing and test operations to maintain confidentiality and integrity of the MRTD and of its manufacturing and test data (to prevent any possible copy, modification,
retention, theft or unauthorized use).
 A.MRTD_Delivery: Procedures shall guarantee the control of
the TOE delivery and storage process and conformance to its
objectives: (1) procedures shall ensure protection of TOE material/information under delivery and storage, (2) procedures
shall ensure that corrective actions are taken in case of improper operation in the delivery process and storage, and (3)
procedures shall ensure that people dealing with the procedure for delivery have got the required skill.
In addition, A. Pers_Agent assumes the correctness of the data and
keys on the final MRTD’s chip.
Thus, the main aspects of A.PPROCESS-SEC-IC are also addressed by
the assumptions in this ST, and there are no contradictions in the assumptions.
Table 6: Assumptions of the Platform ST.
2.2.6.2
Assessment of Platform Security Objectives and SFRs for the Operational Environment
There are the following significant Platform Security Objectives for the Operational Environment that have
to be considered.
Significant Platform Objective for the Environment Relevance for Composite ST
24 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
OE.APPLET
The platform objective for the environment states
that applets loaded post-issuance do not contain
native methods. This assumption leads to appropriate directives in the user guidance [Guidance].
OE.VERIFICATION
The platform objective for the environment targets the applet code verification. In the context of
this ST the TOE applet code is loaded from ROM
only and was verified before ROM mask production. Regarding post-issuance loading of third
party applets, this objective for the environment
leads to appropriate directives in the user guidance [Guidance]. There it is stated that all applets
loaded to the TOE have to be verified.
According to the document [JIL_1], the corresponding objective for the environment in [Guidance] is
extended to the following:
OE.VERIFICATION
All the bytecodes shall be verified at least once, before the loading, before the installation or before the
execution, depending on the card capabilities, in order to ensure that each bytecode is valid at execution time.
Additionally, the applet shall follow all the recommendations, if any, mandated in the platform guidance for maintaining the isolation property of the
platform.
OE.USE_DIAG
The platform objective for the environment covers
secure communication during packaging, finishing
and personalisation. This is corresponding to
OT.Data_Int of this composite ST.
OE.USE_KEYS
The platform objective for the environment is corresponding to OE.MRTD_Manufact of this ST regarding the packaging, finishing and personalisation phase.
OE.PROCESS_SEC_IC
OE.MRTD_Manufact states that during all manufacturing and test operations, security procedures
shall be used through phases 4, 5 and 6 to maintain confidentiality and integrity of the TOE and its
manufacturing and test data.
OE.MRTD_ Delivery states that procedures shall
ensure protection of TOE material/information
under delivery including the following objectives:
25 of 97

non-disclosure of any security relevant information,

identification of the element under delivery,

meet confidentiality rules (confidentiality
level, transmittal form, reception acknowledgment),

physical protection to prevent external
damage,

secure storage and handling procedures,

traceability of TOE during delivery including the following parameters:
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
o
origin and shipment details,
o
reception, reception acknowledgement,
o
location material/information.
The objectives for the environment include also
corrective actions in case of improper operation in
the delivery process and that people dealing with
the procedure for delivery have got the required
skill, training and knowledge to meet the procedure requirements.
Thus, these two objectives are in-line with the
platform objective OE.PROCESS_SEC_IC. There is
no contradiction to the platform objective.
According to the document [JIL_1], an additional ob- This objective for the environment is relevant,
jective for the environment is necessary for an open since it targets additional applets loaded to the
TOE. Thus it leads to an appropriate objective for
and isolating platform:
the environment in the user guidance [Guidance].
OE.CODE-EVIDENCE
For application code loaded pre-issuance, evaluated technical measures implemented by the TOE or
audited organizational measures must ensure that
loaded application has not been changed since the
code verifications required in OE.VERIFICATION.
For application code loaded post-issuance and verified off-card according to the requirements of
OE.VERIFICATION, the verification authority shall
provide digital evidence to the TOE that the application code has not been modified after the code
verification and that he is the actor who per-formed
code verification.
For application code loaded post-issuance and partially or entirely verified on-card, technical measures
must ensure that the verification re-quired in
OE.VERIFICATION are performed. On-card bytecode
verifier is out of the scope of this Protection Profile.
Application Note: The technical measure to fulfill
OE.VERIFICATION is the bytecode verifier provided
by the Java card OS manufacturer. For application
code loaded pre-issuance, organizational measures
must ensure that a loaded application has not been
changed since the code verification. For application
code loaded post-issuance, the verification authority shall provide digital evidence that the application
code has not been modified after the code verification and that he is the actor who performed code
verification. This can be achieved by electronic signature of the application code, after code verification, by the actor who performed verification.

This chapter has been taken from [PP0056] with minor modifications.
3.1 Introduction
3.1.1 Assets
The assets to be protected by the TOE include the User Data on the MRTD’s chip.
3.1.1.1
Logical MRTD sensitive User Data
Sensitive biometric reference data (EF.DG3, EF.DG4).
PP application note 8: Due to interoperability reasons the ‘ICAO Doc 9303’ [ICAODoc] requires that Basic
Inspection Systems must have access to logical MRTD data DG1, DG2, DG5 to DG16. Note the BAC mechanisms may not resist attacks with high attack potential (cf. [PP0055]).
3.1.1.2
Authenticity of the MRTD’s chip
The authenticity of the MRTD’s chip personalized by the issuing State or Organization for the MRTD holder
is used by the traveler to prove his possession of a genuine MRTD.
3.1.2 Subjects
This security target considers the following subjects:
3.1.2.1
Manufacturer
The generic term for the IC Manufacturer producing the integrated circuit and the MRTD Manufacturer
completing the IC to the MRTD’s chip. The Manufacturer is the default user of the TOE during the Phase 2
Manufacturing. The TOE does not distinguish between the users IC Manufacturer and MRTD Manufacturer
using this role Manufacturer.
3.1.2.2
Personalization Agent
The agent is acting on behalf of the issuing State or Organization to personalize the MRTD for the holder by
some or all of the following activities: (i) establishing the identity of the holder for the biographic data in
the MRTD, (ii) enrolling the biometric reference data of the MRTD holder i.e. the portrait, the encoded
finger image(s) and/or the encoded iris image(s), (iii) writing these data on the physical and logical MRTD
for the holder as defined for global, international and national interoperability, (iv) writing the initial TSF
data and (v) signing the Document Security Object.
3.1.2.3
Country Verifying Certification Authority
The Country Verifying Certification Authority (CVCA) enforces the privacy policy of the issuing State or Organization with respect to the protection of sensitive biometric reference data stored in the MRTD. The
CVCA represents the country specific root of the PKI of Inspection Systems and creates the Document Verifier Certificates within this PKI. The updates of the public key of the CVCA are distributed in the form of
Country Verifying CA Link-Certificates.
3.1.2.4
Document Verifier
The Document Verifier (DV) enforces the privacy policy of the receiving State with respect to the protection
of sensitive biometric reference data to be handled by the Extended Inspection Systems. The Document
Verifier manages the authorization of the Extended Inspection Systems for the sensitive data of the MRTD
28 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
in the limits provided by the issuing States or Organizations in the form of the Document Verifier Certificates.
3.1.2.5
Terminal
A terminal is any technical system communicating with the TOE through the contactless interface.
3.1.2.6
Inspection system (IS)
A technical system used by the border control officer of the receiving State (i) examining an MRTD presented
by the traveler and verifying its authenticity and (ii) verifying the traveler as MRTD holder. The Basic Inspection System (BIS) (i) contains a terminal for the contactless communication with the MRTD’s chip, (ii) implements the terminals part of the Basic Access Control Mechanism and (iii) gets the authorization to read the
logical MRTD under the Basic Access Control by optical reading the MRTD or other parts of the passport
book providing this information. The General Inspection System (GIS) is a Basic Inspection System which
implements additionally the Chip Authentication Mechanism. The Extended Inspection System (EIS) in addition to the General Inspection System (i) implements the Terminal Authentication Protocol and (ii) is authorized by the issuing State or Organization through the Document Verifier of the receiving State to read
the sensitive biometric reference data. The security attributes of the EIS are defined of the Inspection System Certificates.
3.1.2.7
MRTD Holder
The rightful holder of the MRTD for whom the issuing State or Organization personalized the MRTD.
3.1.2.8
Traveler
Person presenting the MRTD to the inspection system and claiming the identity of the MRTD holder.
3.1.2.9
Attacker
A threat agent trying (i) to manipulate the logical MRTD without authorization, (ii) to read sensitive biometric reference data (i.e. EF.DG3, EF.DG4) or (iii) to forge a genuine MRTD.
PP Application note 9: Note that an attacker trying to identify and to trace the movement of the MRTD’s
chip remotely (i.e. without knowing or optically reading the physical MRTD) is not considered by this security
target since this can only be averted by the BAC mechanism using the “weak” Document Basic Access Keys
that is covered by [PP0055]. The same holds for the confidentiality of the user data EF.DG1, EF.DG2, EF.DG5
to EF.DG16 as well as EF.SOD and EF.COM.
PP Application note 10: An impostor is attacking the inspection system as TOE IT environment independent
on using a genuine, counterfeit or forged MRTD. Therefore the impostor may use results of successful attacks against the TOE but the attack itself is not relevant for the TOE.
3.2 Assumptions
The assumptions describe the security aspects of the environment in which the TOE will be used or is intended to be used.
3.2.1 A.MRTD_Manufact MRTD manufacturing on steps 4 to 6
It is assumed that appropriate functionality testing of the MRTD is used. It is assumed that security procedures are used during all manufacturing and test operations to maintain confidentiality and integrity of the
MRTD and of its manufacturing and test data (to prevent any possible copy, modification, retention, theft
or unauthorized use).

3.2.2 A.MRTD_Delivery MRTD delivery during steps 4 to 6
Procedures shall guarantee the control of the TOE delivery and storage process and conformance to its
objectives:

Procedures shall ensure protection of TOE material/information under delivery and storage.

Procedures shall ensure that corrective actions are taken in case of improper operation in the delivery process and storage.

Procedures shall ensure that people dealing with the procedure for delivery have got the required
skill.
3.2.3 A.Pers_Agent Personalization of the MRTD’s chip
The Personalization Agent ensures the correctness of (i) the logical MRTD with respect to the MRTD holder,
(ii) the Document Basic Access Keys, (iii) the Chip Authentication Public Key (EF.DG14) if stored on the
MRTD’s chip, and (iv) the Document Signer Public Key Certificate (if stored on the MRTD’s chip). The Personalization Agent signs the Document Security Object. The Personalization Agent bears the Personalization
Agent Authentication to authenticate himself to the TOE by symmetric cryptographic mechanisms.
3.2.4 A.Insp_Sys Inspection Systems for global interoperability
The Inspection System is used by the border control officer of the receiving State (i) examining an MRTD
presented by the traveler and verifying its authenticity and (ii) verifying the traveler as MRTD holder. The
Basic Inspection System for global interoperability (i) includes the Country Signing CA Public Key and the
Document Signer Public Key of each issuing State or Organization, and (ii) implements the terminal part of
the Basic Access Control. The Basic Inspection System reads the logical MRTD under Basic Access Control
and performs the Passive Authentication to verify the logical MRTD. The General Inspection System in addition to the Basic Inspection System implements the Chip Authentication Mechanism. The General Inspection System verifies the authenticity of the MRTD’s chip during inspection and establishes secure messaging
with keys established by the Chip Authentication Mechanism. The Extended Inspection System in addition
to the General Inspection System (i) supports the Terminal Authentication Protocol and (ii) is authorized by
the issuing State or Organization through the Document Verifier of the receiving State to read the sensitive
biometric reference data.
3.2.5 A.Signature_PKI PKI for Passive Authentication
The issuing and receiving States or Organizations establish a public key infrastructure for passive authentication i.e. digital signature creation and verification for the logical MRTD. The issuing State or Organization
runs a Certification Authority (CA) which securely generates, stores and uses the Country Signing CA Key
pair. The CA keeps the Country Signing CA Private Key secret and is recommended to distribute the Country
Signing CA Public Key to ICAO, all receiving States maintaining its integrity. The Document Signer (i) generates the Document Signer Key Pair, (ii) hands over the Document Signer Public Key to the CA for certification,
(iii) keeps the Document Signer Private Key secret and (iv) uses securely the Document Signer Private Key
for signing the Document Security Objects of the MRTDs. The CA creates the Document Signer Certificates
for the Document Signer Public Keys that are distributed to the receiving States and Organizations.
3.2.6 A.Auth_PKI PKI for Inspection Systems
The issuing and receiving States or Organizations establish a public key infrastructure for card verifiable
certificates of the Extended Access Control. The Country Verifying Certification Authorities, the Document
Verifier and Extended Inspection Systems hold authentication key pairs and certificates for their public keys
encoding the access control rights. The Country Verifying Certification Authorities of the issuing States or
30 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
Organizations are signing the certificates of the Document Verifier and the Document Verifiers are signing
the certificates of the Extended Inspection Systems of the receiving States or Organizations. The issuing
States or Organizations distribute the public keys of their Country Verifying Certification Authority to their
MRTD’s chip.
3.3 Threats
This section describes the threats to be averted by the TOE independently or in collaboration with its IT
environment. These threats result from the TOE method of use in the operational environment and the
assets stored in or protected by the TOE.
PP Application note 11: The threats T.Chip_ID and T.Skimming (cf. [PP0055]) are averted by the mechanisms
described in the BAC PP [PP0055] (cf. P.BAC-PP) which cannot withstand an attack with high attack potential
thus these are not addressed here. T.Chip_ID addresses the threat of tracing the movement of the MRTD
by identifying remotely the MRTD’s chip by establishing or listening to communications through the contactless communication interface. T.Skimming addresses the threat of imitating the inspection system to
read the logical MRTD or parts of it via the contactless communication channel of the TOE. Both attacks are
conducted by an attacker who cannot read the MRZ or who does not know the physical MRTD in advance.
The TOE in collaboration with its IT environment shall avert the threats as specified below.
3.3.1 T.Read_Sensitive_Data Read the sensitive biometric reference data
Adverse action:
An attacker tries to gain the sensitive biometric reference data through the communication interface of the MRTD’s chip. The attack T.Read_Sensitive_Data is similar to the threat T.Skimming (cf. [PP0055]) in respect of the attack path (communication interface) and the motivation (to get data stored on the MRTD’s chip) but
differs from those in the asset under the attack (sensitive biometric reference data
vs. digital MRZ, digitized portrait and other data), the opportunity (i.e. knowing Document Basic Access Keys) and therefore the possible attack methods. Note, that the
sensitive biometric reference data are stored only on the MRTD’s chip as private
sensitive personal data whereas the MRZ data and the portrait are visually readable
on the physical MRTD as well.
Threat agent:
having high attack potential, knowing the Document Basic Access Keys, being in
possession of a legitimate MRTD
Asset:
confidentiality of sensitive logical MRTD (i.e. biometric reference) data.
3.3.2 T.Forgery Forgery of data on MRTD’s chip
Adverse action:
An attacker alters fraudulently the complete stored logical MRTD or any part of it
including its security related data in order to deceive on an inspection system by
means of the changed MRTD holder’s identity or biometric reference data. This
threat comprises several attack scenarios of MRTD forgery. The attacker may alter
the biographical data on the biographical data page of the passport book, in the
printed MRZ and in the digital MRZ to claim another identity of the traveler. The
attacker may alter the printed portrait and the digitized portrait to overcome the
visual inspection of the inspection officer and the automated biometric authentication mechanism by face recognition. The attacker may alter the biometric reference
data to defeat automated biometric authentication mechanism of the inspection
system. The attacker may combine data groups of different logical MRTDs to create
a new forged MRTD, e.g. the attacker writes the digitized portrait and optional biometric reference finger data read from the logical MRTD of a traveler into another
31 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
MRTD’s chip leaving their digital MRZ unchanged to claim the identity of the holder
this MRTD. The attacker may also copy the complete unchanged logical MRTD to
another contactless chip.
Threat agent:
having high attack potential, being in possession of one or more legitimate MRTDs
Asset:
authenticity of logical MRTD data.
3.3.3 T.Counterfeit MRTD’s chip
Adverse action:
An attacker with high attack potential produces an unauthorized copy or reproduction of a genuine MRTD’s chip to be used as part of a counterfeit MRTD. This violates
the authenticity of the MRTD’s chip used for authentication of a traveler by possession of a MRTD. The attacker may generate a new data set or extract completely or
partially the data from a genuine MRTD’s chip and copy them on another appropriate chip to imitate this genuine MRTD’s chip.
Threat agent:
having high attack potential, being in possession of one or more legitimate MRTDs
Asset:
authenticity of logical MRTD data.
The TOE shall avert the threats as specified below.
3.3.4 T.Abuse-Func Abuse of Functionality
Adverse action:
An attacker may use functions of the TOE which shall not be used in “Operational
Use” phase in order (i) to manipulate User Data, (ii) to manipulate (explore, bypass,
deactivate or change) security features or functions of the TOE or (iii) to disclose or
to manipulate TSF Data. This threat addresses the misuse of the functions for the
initialization and the personalization in the operational state after delivery to MRTD
holder.
Threat agent:
having high attack potential, being in possession of a legitimate MRTD
Asset:
confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF
3.3.5 T.Information_Leakage Information Leakage from MRTD’s chip
Adverse action:
An attacker may exploit information which is leaked from the TOE during its usage
in order to disclose confidential TSF data. The information leakage may be inherent
in the normal operation or caused by the attacker. Leakage may occur through emanations, variations in power consumption, I/O characteristics, clock frequency, or
by changes in processing time requirements. This leakage may be interpreted as a
covert channel transmission but is more closely related to measurement of operating parameters which may be derived either from measurements of the contactless
interface (emanation) or direct measurements (by contact to the chip still available
even for a contactless chip) and can then be related to the specific operation being
performed. Examples are the Differential Electromagnetic Analysis (DEMA) and the
Differential Power Analysis (DPA). Moreover the attacker may try actively to enforce information leakage by fault injection (e.g. Differential Fault Analysis).
Threat agent:
having high attack potential, being in possession of a legitimate MRTD
Asset:
confidentiality of logical MRTD and TSF data
32 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
3.3.6 T.Phys-Tamper Physical Tampering
Adverse action:
An attacker may perform physical probing of the MRTD’s chip in order (i) to disclose
TSF Data, or (ii) to disclose/reconstruct the MRTD’s chip Embedded Software. An
attacker may physically modify the MRTD’s chip in order to (i) modify security features or functions of the MRTD’s chip, (ii) modify security functions of the MRTD’s
chip Embedded Software, (iii) modify User Data or (iv) to modify TSF data. The physical tampering may be focused directly on the disclosure or manipulation of TOE
User Data (e.g. the biometric reference data for the inspection system) or TSF Data
(e.g. authentication key of the MRTD’s chip) or indirectly by preparation of the TOE
to following attack methods by modification of security features (e.g. to enable information leakage through power analysis). Physical tampering requires direct interaction with the MRTD’s chip internals. Techniques commonly employed in IC failure analysis and IC reverse engineering efforts may be used. Before that, the hardware security mechanisms and layout characteristics need to be identified. Determination of software design including treatment of User Data and TSF Data may
also be a pre-requisite. The modification may result in the deactivation of a security
function. Changes of circuitry or data can be permanent or temporary.
Threat agent:
having high attack potential, being in possession of a legitimate MRTD
Asset:
confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF
3.3.7 T.Malfunction Malfunction due to Environmental Stress
Adverse action:
An attacker may cause a malfunction of TSF or of the MRTD’s chip Embedded Software by applying environmental stress in order to (i) deactivate or modify security
features or functions of the TOE or (ii) circumvent, deactivate or modify security
functions of the MRTD’s chip Embedded Software. This may be achieved e.g. by
operating the MRTD’s chip outside the normal operating conditions, exploiting errors in the MRTD’s chip Embedded Software or misusing administration function.
To exploit these vulnerabilities an attacker needs information about the functional
operation.
Threat agent:
having high attack potential, being in possession of a legitimate MRTD
Asset:
confidentiality and authenticity of logical MRTD and TSF data, correctness of TSF
3.4 Organizational security policies
The TOE shall comply with the following Organizational Security Policies (OSP) as security rules, procedures,
practices, or guidelines imposed by an organization upon its operations (see CC part 1 [CC_1], section 3.2).
3.4.1 P.BAC-PP Fulfillment of the Basic Access Control Protection Profile.
The issuing States or Organizations ensures that successfully authenticated Basic Inspection Systems have
read access to logical MRTD data DG1, DG2, DG5 to DG16 the ‘ICAO Doc 9303’ [ICAODoc] as well as to the
data groups Common and Security Data. The MRTD is successfully evaluated and certified in accordance
with the ‘Common Criteria Protection Profile Machine Readable Travel Document with „ICAO Application",
Basic Access Control’ [PP0055] in order to ensure the confidentiality of standard user data and preventing
the traceability of the MRTD data.
PP Application note 12: The organizational security policy P.Personal_Data drawn from the ‘ICAO Doc 9303’
[ICAODoc] is addressed by the [PP0055] (cf. P.BAC-PP). The confidentiality of the personal data other than
EF.DG3 and EF.DG4 is ensured by the BAC mechanism. Note the BAC mechanisms may not resist attacks
with high attack potential (cf. [PP0055]). The TOE shall protect the sensitive biometric reference data in
33 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
EF.DG3 and EF.DG4 against attacks with high attack potential. Due to the different resistance the protection
of EF.DG3 and EF.DG4 on one side and the other EF.SOD, EF.COM, EF.DG1, EF.DG2 and EF.DG5 to EF.DG16
on the other side are addressed in separated protection profiles and security targets, which results in technically separated evaluations (at least for classes ASE and VAN) and certificates (cf. also PP application note
1).
3.4.2 P.Sensitive_Data Privacy of sensitive biometric reference data
The biometric reference data of finger(s) (EF.DG3) and iris image(s) (EF.DG4) are sensitive private personal
data of the MRTD holder. The sensitive biometric reference data can be used only by inspection systems
which are authorized for this access at the time the MRTD is presented to the inspection system (Extended
Inspection Systems). The issuing State or Organization authorizes the Document Verifiers of the receiving
States to manage the authorization of inspection systems within the limits defined by the Document Verifier
Certificate. The MRTD’s chip shall protect the confidentiality and integrity of the sensitive private personal
data even during transmission to the Extended Inspection System after Chip Authentication.
3.4.3 P.Manufact Manufacturing of the MRTD’s chip
The Initialization Data are written by the IC Manufacturer to identify the IC uniquely. The MRTD Manufacturer writes the Pre-personalization Data which contains at least the Personalization Agent Key.
3.4.4 P.Personalization Personalization of the MRTD by issuing State or Organization only
The issuing State or Organization guarantees the correctness of the biographical data, the printed portrait
and the digitized portrait, the biometric reference data and other data of the logical MRTD with respect to
the MRTD holder. The personalization of the MRTD for the holder is performed by an agent authorized by
the issuing State or Organization only.

The TOE must ensure that the logical MRTD data in EF.DG1 to EF.DG16, the Document security object according to LDS [ICAODoc] and the TSF data can be written by authorized Personalization Agents only. The
logical MRTD data in EF.DG1 to EF.DG16 and the TSF data may be written only during and cannot be changed
after its personalization. The Document security object can be updated by authorized Personalization
Agents if data in the data groups EF.DG3 to EF.DG16 are added.
PP Application note 13: The OT.AC_Pers implies that
(1) the data of the LDS groups written during personalization for MRTD holder (at least EF.DG1 and
EF.DG2) cannot be changed by write access after personalization,
(2) the Personalization Agents may (i) add (fill) data into the LDS data groups not written yet, and (ii)

4.1.2 OT.Data_Int Integrity of personal data
The TOE must ensure the integrity of the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. The TOE must ensure the integrity of the logical MRTD data during their
transmission to the General Inspection System after Chip Authentication.
4.1.3 OT.Sens_Data_Conf Confidentiality of sensitive biometric reference data
The TOE must ensure the confidentiality of the sensitive biometric reference data (EF.DG3 and EF.DG4) by
granting read access only to authorized Extended Inspection Systems. The authorization of the inspection
system is drawn from the Inspection System Certificate used for the successful authentication and shall be
a non-strict subset of the authorization defined in the Document Verifier Certificate in the certificate chain
to the Country Verifier Certification Authority of the issuing State or Organization. The TOE must ensure the
confidentiality of the logical MRTD data during their transmission to the Extended Inspection System. The
confidentiality of the sensitive biometric reference data shall be protected against attacks with high attack
potential.
4.1.4 OT.Identification Identification and Authentication of the TOE

4.1.5 OT.Chip_Auth_Proof Proof of MRTD’s chip authenticity
The TOE must support the General Inspection Systems to verify the identity and authenticity of the MRTD’s
chip as issued by the identified issuing State or Organization by means of the Chip Authentication as defined
in [TR-03110]. The authenticity proof provided by MRTD’s chip shall be protected against attacks with high
attack potential.
PP application note 14: The OT.Chip_Auth_Proof implies the MRTD’s chip to have (i) a unique identity as
given by the MRTD’s Document Number, (ii) a secret to prove its identity by knowledge i.e. a private authentication key as TSF data. The TOE shall protect this TSF data to prevent their misuse. The terminal shall
have the reference data to verify the authentication attempt of MRTD’s chip i.e. a certificate for the Chip
Authentication Public Key that matches the Chip Authentication Private Key of the MRTD’s chip. This certificate is provided by (i) the Chip Authentication Public Key (EF.DG14) in the LDS [ICAODoc] and (ii) the hash
value of the Chip Authentication Public Key in the Document Security Object signed by the Document Signer.
The following TOE security objectives address the protection provided by the MRTD’s chip independent of
the TOE environment.
4.1.6 OT.Prot_Abuse-Func Protection against Abuse of Functionality

It has to be ensured by the issuing State or Organization, that the TOE is additionally successfully evaluated
and certified in accordance with the ‘Common Criteria Protection Profile Machine Readable Travel Document with „ICAO Application", Basic Access Control’ [PP0055]. This is necessary to cover the BAC mechanism
ensuring the confidentiality of standard user data and preventing the traceability of the MRTD data. Note
that due to the differences within the assumed attack potential the addressed evaluation and certification

4.2.1.8
OE.Active_Auth_Key_MRTD MRTD Active Authentication Key
The issuing State or Organization has to establish the necessary public key infrastructure in order to (i) generate the MRTD’s Active Authentication Key Pair, (ii) sign and store the Active Authentication Public Key in
the Active Authentication Public Key data in EF.DG15 and (iii) support inspection systems of receiving States
or organizations to verify the authenticity of the MRTD’s chip used for genuine MRTD by certification of the
Active Authentication Public Key by means of the Document Security Object.

cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
Justification for the added objective for the environment OE.Active_Auth_Key_MRTD:
This security objective for the operational environment addresses the optional Active Authentication mechanism. It neither mitigates a threat meant to be addressed by security objectives for the TOE – this is
achieved by chip authentication alone - nor fulfils an OSP meant to be addressed by security objectives for
the TOE.
4.2.2 Receiving State or Organization
The receiving State or Organization will implement the following security objectives of the TOE environment.
4.2.2.1
OE.Exam_MRTD Examination of the MRTD passport book
The inspection system of the receiving State or Organization must examine the MRTD presented by the
traveler to verify its authenticity by means of the physical security measures and to detect any manipulation
of the physical MRTD. The Basic Inspection System for global interoperability (i) includes the Country Signing
CA Public Key and the Document Signer Public Key of each issuing State or Organization, and (ii) implements
the terminal part of the Basic Access Control [ICAODoc]. Additionally General Inspection Systems and Extended Inspection Systems perform the Chip Authentication Protocol to verify the Authenticity of the presented MRTD’s chip.
4.2.2.2
OE.Passive_Auth_Verif Verification by Passive Authentication
The border control officer of the receiving State uses the inspection system to verify the traveler as MRTD
holder. The inspection systems must have successfully verified the signature of Document Security Objects
and the integrity data elements of the logical MRTD before they are used. The receiving States and Organizations must manage the Country Signing CA Public Key and the Document Signer Public Key maintaining
their authenticity and availability in all inspection systems.
4.2.2.3
OE.Prot_Logical_MRTD Protection of data from the logical MRTD
The inspection system of the receiving State or Organization ensures the confidentiality and integrity of the
data read from the logical MRTD. The inspection system will prevent eavesdropping to their communication
with the TOE before secure messaging is successfully established based on the Chip Authentication Protocol.
PP application note 17: The figure 2.1 in [TR-03110] supposes that the GIS and the EIS follow the order (i)
running the Basic Access Control Protocol, (ii) reading and verifying only those parts of the logical MRTD
that are necessary to know for the Chip Authentication Mechanism (i.e. Document Security Object and Chip
Authentication Public Key), (iii) running the Chip Authentication Protocol, and (iv) reading and verifying the
less-sensitive data of the logical MRTD after Chip Authentication. The supposed sequence has the advantage
that the less-sensitive data are protected by secure messaging with cryptographic keys based on the Chip
Authentication Protocol which quality is under control of the TOE. The inspection system will prevent additionally eavesdropping to their communication with the TOE before secure messaging is successfully established based on the Chip Authentication Protocol. Note that reading the lesssensitive data directly after
Basic Access Control Mechanism is allowed and is not assumed as threat in this ST. But the TOE ensures that
reading of sensitive data is possible after successful Chip Authentication and Terminal Authentication Protocol only.
4.2.2.4
OE.Ext_Insp_Systems: Authorization of Extended Inspection Systems
The Document Verifier of receiving States or Organizations authorizes Extended Inspection Systems by creation of Inspection System Certificates for access to sensitive biometric reference data of the logical MRTD.
The Extended Inspection System authenticates themselves to the MRTD’s chip for access to the sensitive
biometric reference data with its private Terminal Authentication Key and its Inspection System Certificate.

Table 8: Overview of the security objectives coverage
The OSP P. BAC-PP is directly addressed by the OE.BAC-PP.
The OSP P.Manufact “Manufacturing of the MRTD’s chip” requires a unique identification of the IC by means
of the Initialization Data and the writing of the Pre-personalization Data as being fulfilled by
OT.Identification.
The OSP P.Personalization “Personalization of the MRTD by issuing State or Organization only” addresses
the (i) the enrolment of the logical MRTD by the Personalization Agent as described in the security objective
for the TOE environment OE.Personalization “Personalization of logical MRTD”, and (ii) the access control
for the user data and TSF data as described by the security objective OT.AC_Pers “Access Control for Personalization of logical MRTD”. Note the manufacturer equips the TOE with the Personalization Agent Key(s)
according to OT.Identification “Identification and Authentication of the TOE”. The security objective
OT.AC_Pers limits the management of TSF data and the management of TSF to the Personalization Agent.
The OSP P.Sensitive_Data “Privacy of sensitive biometric reference data” is fulfilled and the threat
T.Read_Sensitive_Data “Read the sensitive biometric reference data” is countered by the TOE-objective
OT.Sens_Data_Conf “Confidentiality of sensitive biometric reference data” requiring that read access to
EF.DG3 and EF.DG4 (containing the sensitive biometric reference data) is only granted to authorized inspection systems. Furthermore it is required that the transmission of these data ensures the data’s confidentiality. The authorization bases on Document Verifier certificates issued by the issuing State or Organization
as required by OE.Authoriz_Sens_Data “Authorization for use of sensitive biometric reference data”. The
40 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
Document Verifier of the receiving State has to authorize Extended Inspection Systems by creating appropriate Inspection System certificates for access to the sensitive biometric reference data as demanded by
OE.Ext_Insp_Systems “Authorization of Extended Inspection Systems”.
The threat T.Forgery “Forgery of data on MRTD’s chip” addresses the fraudulent alteration of the complete
stored logical MRTD or any part of it. The security objective OT.AC_Pers “Access Control for Personalization
of logical MRTD“ requires the TOE to limit the write access for the logical MRTD to the trustworthy Personalization Agent (cf. OE.Personalization). The TOE will protect the integrity of the stored logical MRTD according the security objective OT.Data_Int “Integrity of personal data” and OT.Prot_Phys-Tamper “Protection against Physical Tampering”. The examination of the presented MRTD passport book according to
OE.Exam_MRTD “Examination of the MRTD passport book” shall ensure that passport book does not contain a sensitive contactless chip which may present the complete unchanged logical MRTD. The TOE environment will detect partly forged logical MRTD data by means of digital signature which will be created
according to OE.Pass_Auth_Sign “Authentication of logical MRTD by Signature” and verified by the inspection system according to OE.Passive_Auth_Verif “Verification by Passive Authentication”.
The threat T.Counterfeit “MRTD’s chip” addresses the attack of unauthorized copy or reproduction of the
genuine MRTD chip. This attack is thwarted by chip an identification and authenticity proof required by
OT.Chip_Auth_Proof “Proof of MRTD’s chip authentication” using a authentication key pair to be generated
by the issuing State or Organization. The Public Chip Authentication Key has to be written into EF.DG14 and
signed by means of Documents Security Objects as demanded by OE.Auth_Key_MRTD “MRTD Authentication Key”. According to OE.Exam_MRTD “Examination of the MRTD passport book” the General Inspection
system has to perform the Chip Authentication Protocol to verify the authenticity of the MRTD’s chip. It is
also adressed by OT.Active_Auth_Proof which erquires an optional Active Authentication mechanism. The
corresponding support of the Active Authentication mechanism by the environment is adressed by
OE.Active_Auth_Key_MRTD.
The threat T.Abuse-Func “Abuse of Functionality” addresses attacks of misusing MRTD’s functionality to
disable or bypass the TSFs. The security objective for the TOE OT.Prot_Abuse-Func “Protection against
abuse of functionality” ensures that the usage of functions which may not be used in the “Operational Use”
phase is effectively prevented. Therefore attacks intending to abuse functionality in order to disclose or
manipulate critical (User) Data or to affect the TOE in such a way that security features or TOE’s functions
may be bypassed, deactivated, changed or explored shall be effectively countered.
The threats T.Information_Leakage “Information Leakage from MRTD’s chip”, T.Phys-Tamper “Physical
Tampering” and T.Malfunction “Malfunction due to Environmental Stress” are typical for integrated circuits
like smart cards under direct attack with high attack potential. The protection of the TOE against these
threats is addressed by the directly related security objectives OT.Prot_Inf_Leak “Protection against Information Leakage”, OT.Prot_Phys-Tamper “Protection against Physical Tampering” and
OT.Prot_Malfunction “Protection against Malfunctions”.
The assumption A.MRTD_Manufact “MRTD manufacturing on step 4 to 6” is covered by the security objective for the TOE environment OE.MRTD_Manufact “Protection of the MRTD Manufacturing” that requires
to use security procedures during all manufacturing steps.
The assumption A.MRTD_ Delivery “MRTD delivery during step 4 to 6” is covered by the security objective
for the TOE environment OE.MRTD_ Delivery “Protection of the MRTD delivery” that requires to use security procedures during delivery steps of the MRTD.
The assumption A.Pers_Agent “Personalization of the MRTD’s chip” is covered by the security objective for
the TOE environment OE.Personalization “Personalization of logical MRTD” including the enrolment, the
protection with digital signature and the storage of the MRTD holder personal data.
The examination of the MRTD passport book addressed by the assumption A.Insp_Sys “Inspection Systems
for global interoperability” is covered by the security objectives for the TOE environment OE.Exam_MRTD
“Examination of the MRTD passport book” which requires the inspection system to examine physically the
41 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
MRTD, the Basic Inspection System to implement the Basic Access Control, and the General Inspection Systems and Extended Inspection Systems to implement and to perform the Chip Authentication Protocol to
verify the Authenticity of the presented MRTD’s chip. The security objectives for the TOE environment
OE.Prot_Logical_MRTD “Protection of data from the logical MRTD” require the Inspection System to protect the logical MRTD data during the transmission and the internal handling.
The assumption A.Signature_PKI “PKI for Passive Authentication” is directly covered by the security objective for the TOE environment OE.Pass_Auth_Sign “Authentication of logical MRTD by Signature” covering
the necessary procedures for the Country Signing CA Key Pair and the Document Signer Key Pairs. The implementation of the signature verification procedures is covered by OE.Exam_MRTD “Examination of the
MRTD passport book”.
The assumption A.Auth_PKI “PKI for Inspection Systems” is covered by the security objective for the TOE
environment OE.Authoriz_Sens_Data “Authorization for use of sensitive biometric reference data” requires
the CVCA to limit the read access to sensitive biometrics by issuing Document Verifier certificates for authorized receiving States or Organizations only. The Document Verifier of the receiving State is required by
OE.Ext_Insp_Systems “Authorization of Extended Inspection Systems” to authorize Extended Inspection
Systems by creating Inspection System Certificates. Therefore, the receiving issuing State or Organization
has to establish the necessary public key infrastructure.

5 Extended Components Definition
This security target uses components defined as extensions to CC part 2. Some of these components are
defined in [PP0002], other components are defined in the protection profile [PP0056]. This chapter has
been taken from [PP0056] with minor modifications.
5.1 Definition of the Family FAU_SAS
To define the security functional requirements of the TOE a sensitive family (FAU_SAS) of the Class FAU
(Security Audit) is defined here. This family describes the functional requirements for the storage of audit
data. It has a more general approach than FAU_GEN, because it does not necessarily require the data to be
generated by the TOE itself and because it does not give specific details of the content of the audit records.
The family “Audit data storage (FAU_SAS)” is specified as follows.

5.3 Definition of the Family FIA_API
To describe the IT security functional requirements of the TOE a sensitive family (FIA_API) of the Class FIA
(Identification and authentication) is defined here. This family describes the functional requirements for the
proof of the claimed identity for the authentication verification by an external entity where the other families of the class FIA address the verification of the identity of an external entity.
PP application note 18: The other families of the Class FIA describe only the authentication verification of
users’ identity performed by the TOE and do not describe the functionality of the user to prove their identity. The following paragraph defines the family FIA_API in the style of the Common Criteria part 2 (cf. [3],
chapter “Explicitly stated IT security requirements (APE_SRE)”) from a TOE point of view.

5.4 Definition of the Family FMT_LIM
The family FMT_LIM describes the functional requirements for the Test Features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE show that no other class is
appropriate to address the specific issues of preventing the abuse of functions by limiting the capabilities
of the functions and by limiting their availability.
The family “Limited capabilities and availability (FMT_LIM)” is specified as follows.
FMT_LIM Limited capabilities and availability
Family behavior
This family defines requirements that limit the capabilities and availability of functions in a combined manner. Note, that FDP_ACF restricts the access to functions whereas the Limited capability of this family requires the functions themselves to be designed in a specific manner.
Component leveling:

FMT_LIM.1
Limited capabilities requires that the TSF is built to provide only the capabilities
(perform action, gather information) necessary for its genuine purpose.
FMT_LIM.2
Limited availability requires that the TSF restrict the use of functions (refer to Limited capabilities (FMT_LIM.1)). This can be achieved, for instance, by removing or
by disabling functions in a specific phase of the TOE’s lifecycle.
Management:
FMT_LIM.1, FMT_LIM.2
There are no management activities foreseen.
Audit:
FMT_LIM.1, FMT_LIM.2
There are no actions defined to be auditable.
To define the IT security functional requirements of the TOE a sensitive family (FMT_LIM) of the Class FMT
(Security Management) is defined here. This family describes the functional requirements for the Test Features of the TOE. The new functional requirements were defined in the class FMT because this class addresses the management of functions of the TSF. The examples of the technical mechanism used in the TOE
show that no other class is appropriate to address the specific issues of preventing the abuse of functions
by limiting the capabilities of the functions and by limiting their availability.

FMT_LIM.2.1
The TSF shall be designed in a manner that limits their availability so that in conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced:
[assignment: Limited capability and availability policy].
PP application note 19: The functional requirements FMT_LIM.1 and FMT_LIM.2 assume that there are two
types of mechanisms (limited capabilities and limited availability) which together shall provide protection
in order to enforce the policy. This also allows that
(i)
the TSF is provided without restrictions in the product in its user environment but its capabilities
are so limited that the policy is enforced or conversely
(ii)
the TSF is designed with test and support functionality that is removed from, or disabled in, the
product prior to the Operational Use Phase.
The combination of both requirements shall enforce the policy.
5.5 Definition of the Family FPT_EMSEC
The sensitive family FPT_EMSEC (TOE Emanation) of the Class FPT (Protection of the TSF) is defined here to
describe the IT security functional requirements of the TOE. The TOE shall prevent attacks against the TOE
and other secret data where the attack is based on external observable physical phenomena of the TOE.
Examples of such attacks are evaluation of TOE’s electromagnetic radiation, simple power analysis (SPA),
differential power analysis (DPA), timing attacks, etc. This family describes the functional requirements for
the limitation of intelligible emanations which are not directly addressed by any other component of CC
part 2 [CC_2].
The family “TOE Emanation (FPT_EMSEC)” is specified as follows.

Table 11: Overview on authentication SFR
Note the Chip Authentication Protocol as defined in this security target includes

the BAC authentication protocol as defined in ‘ICAO Doc 9303’ [ICAODoc] in order to gain access to
the Chip Authentication Public Key in EF.DG14,

the asymmetric key agreement to establish symmetric secure messaging keys between the TOE and
the terminal based on the Chip Authentication Public Key and the Terminal Public Key used later in
the Terminal Authentication Protocol,

the check whether the TOE is able to generate the correct message authentication code with the
expected key for any message received by the terminal.
The BAC mechanism does not provide a security function on its own. The Chip Authentication Protocol may
be used independent of the Terminal Authentication Protocol. But if the Terminal Authentication Protocol
is used the terminal shall use the same public key as presented during the Chip Authentication Protocol.
Please note that Active Authentication was added to this Security Target as an additional optional authentication mechanism.

FIA_UID.1.1
The TSF shall allow
1. to establish the communication channel,
2. to read the Initialization Data if it is not disabled by TSF according to
FMT_MTD.1/INI_DIS
3. to carry out the Chip Authentication Protocol on behalf of the user to be performed before the user is identified.
FIA_UID.1.2
The TSF shall require each user to be successfully identified before allowing any
other TSF-mediated actions on behalf of that user.
PP application note 30: In the Phase 2 “Manufacturing of the TOE” the Manufacturer is the only user role
known to the TOE which writes the Initialization Data and/or Pre-personalization Data in the audit records
of the IC. The MRTD manufacturer may create the user role Personalization Agent for transition from Phase
2 to Phase 3 “Personalization of the MRTD”. The users in role Personalization Agent identify themselves by
means of selecting the authentication key. After personalization in the Phase 3 the Document Basic Access
Keys, the Chip Authentication data and Terminal Authentication Reference Data are written into the TOE.
The Basic Inspection System (cf. PP MRTD BAC [PP0055]) is identified as default user after power up or reset
of the TOE i.e. the TOE will use the Document Basic Access Key to run the BAC Authentication Protocol, to
gain access to the Chip Authentication Reference Data and to run the Chip Authentication Protocol (i.e. the
BAC mechanism is not seen as an independent mechanism in this security target, it is a mandatory part
within the Chip Authentication Protocol, and thus noted here for reasons of completeness). After successful
authentication of the chip the terminal may identify itself as (i) Extended Inspection System by selection of
the templates for the Terminal Authentication Protocol or (ii) if necessary and available by symmetric authentication as Personalization Agent (using the Personalization Agent Key).

The TSF shall prevent reuse of authentication data related to
1. Terminal Authentication Protocol,
2. Authentication Mechanism based on AES20
PP application note 31: The authentication mechanisms may use either a challenge freshly and randomly
generated by the TOE to prevent reuse of a response generated by a terminal in a successful authentication
attempt. However, the authentication of Personalisation Agent may rely on other mechanisms ensuring
protection against replay attacks, such as the use of an internal counter as a diversifier.

Authentication Protocol and the secure messaging established by the Chip Authentication Mechanism.
PP application note 32: Depending on the authentication methods used the Personalization Agent holds (i)
a key for the Symmetric Authentication Mechanism or (ii) an asymmetric key pair for the Terminal Authentication Protocol (e.g. provided by the Extended Access Control PKI in a valid card verifiable certificate with
appropriate encoded access rights). The Basic Access Control Mechanism includes the secure messaging for
all commands exchanged after successful authentication of the inspection system. The Personalization
Agent may use Symmetric Authentication Mechanism without secure messaging mechanism as well if the
personalization environment prevents eavesdropping to the communication between TOE and personalization terminal. The Basic Inspection System shall use the Basic Access Control Authentication Mechanism
with the Document Basic Access Keys and the secure messaging after the mutual authentication. The General Inspection System shall use the secure messaging with the keys generated by the Chip Authentication
Mechanism.
The TOE shall meet the requirement “Re-authenticating (FIA_UAU.6)” as specified below (Common Criteria
Part 2).
FIA_UAU.6 Re-authenticating – Re-authenticating of Terminal by the TOE
Hierarchical to:
No other components.
Dependencies:
No dependencies.
FIA_UAU.6.1
The TSF shall re-authenticate the user under the conditions each command sent to
the TOE after successful run of the Chip Authentication Protocol shall be verified
as being sent by the GIS.
PP application note 33: The Basic Access Control Mechanism and the Chip Authentication Protocol specified
in [ICAODoc] include secure messaging for all commands exchanged after successful authentication of the
Inspection System. The TOE checks by secure messaging in MAC_ENC mode each command based on CMAC,
Retail-MAC or EMAC whether it was sent by the successfully authenticated terminal (see FCS_COP.1/MAC
for further details). The TOE does not execute any command with incorrect message authentication code.
Therefore the TOE reauthenticates the user for each received command and accepts only those commands
received from the previously authenticated user.

1. the successfully authenticated Personalization Agent is allowed to write and
to read the data of the EF.COM, EF.SOD, EF.DG1 to EF.DG16 of the logical
MRTD,
2.
the successfully authenticated Extended Inspection System with the Read access to DG 3 (Fingerprint) granted by the relative certificate holder authorization encoding is allowed to read the data in EF.DG3 of the logical MRTD.
3. the successfully authenticated Extended Inspection System with the Read access to DG 4 (Iris) granted by the relative certificate holder authorization encoding is allowed to read the data in EF.DG4 of the logical MRTD.
FDP_ACF.1.3
The TSF shall explicitly authorize access of subjects to objects based on the following
additional rules: none.
FDP_ACF.1.4
The TSF shall explicitly deny access of subjects to objects based on the rule:
1. A terminal authenticated as CVCA is not allowed to read data in the EF.DG3,
2. A terminal authenticated as CVCA is not allowed to read data in the EF.DG4,
3. A terminal authenticated as DV is not allowed to read data in the EF.DG3,
4. A terminal authenticated as DV is not allowed to read data in the EF.DG4,
5.
Any terminal is not allowed to modify any of the EF.DG1 to EF.DG16 of the
logical MRTD,
6.
Any terminal not being successfully authenticated as Extended Inspection System is not allowed to read any of the EF.DG3 to EF.DG4 of the logical MRTD.
PP application note 35: The relative certificate holder authorization encoded in the CVC of the inspection
system is defined in [TR-03110], Annex A.5.1, table A.8. The TOE verifies the certificate chain established by
the Country Verifying Certification Authority, the Document Verifier Certificate and the Inspection System
Certificate (cf. FMT_MTD.3). The Terminal Authorization is the intersection of the Certificate Holder Authorization in the certificates of the Country Verifying Certification Authority, the Document Verifier Certificate
and the Inspection System Certificate in a valid certificate chain.
PP application note 36: Note that the BAC mechanism controls the read access of the EF.COM, EF.SOD,
EF.DG1, EF.DG2, EF.DG5 to EF.DG16 of the logical MRTD. According to P.BAC-PP these security features of

data in a manner protected from modification, deletion, insertion and replay errors
after Chip Authentication.
FDP_UIT.1.2
The TSF shall be able to determine on receipt of user data, whether modification,
deletion, insertion and replay has occurred after Chip Authentication.
Rationale for Refinement in the PP: Note that the Access Control SFP (cf. FDP_ACF.1.2) allows the Extended
Inspection System (as of [ICAODoc] and [PP0055]) to access the data EF.COM, EF.SOD, EF.DG1, EF.DG2 and
EF.DG5 to EF.DG16 of the logical MRTD. Nevertheless there is explicitly no rule for preventing access to
these data. More over their data integrity (cf. FDP_UIT.1) and confidentiality (cf. FDP_UCT.1) is ensured by
the BAC mechanism being addressed and covered by [PP0055]. The fact that the BAC mechanism is not part
of the security target in hand is addressed by the refinement “after Chip Authentication”.
PP application note 37: FDP_UCT.1 and FDP_UIT.1 require the protection of the User Data transmitted from
the TOE to the terminal by secure messaging with encryption and message authentication codes after successful Chip Authentication to the General Inspection System. The authentication mechanism as part of
Basic Access Control Mechanism and the Chip Authentication Protocol establish different key sets to be
used for secure messaging (each set of keys for the encryption and the message authentication key).

5. domestic Extended Inspection System
6. foreign Extended Inspection System.
FMT_SMR.1.2
The TSF shall be able to associate users with roles.
PP application note 39: Note that the MRTD also maintains the role Basic Inspection System due to a direct
consequence of P.BAC-PP resp. OE.BAC-PP. Nevertheless this role is not explicitly listed in FMT_SMR.1.1,
above since the TSF cannot maintain the role with respect to the assumed high attack potential due to the
known weaknesses of the Document Basic Access Keys.
PP application note 40: The SFR FMT_LIM.1 and FMT_LIM.2 address the management of the TSF and TSF

3. TSF data to be disclosed or manipulated
4. software to be reconstructed and
5. substantial information about construction of TSF to be gathered which may

PP application note 41: The formulation of “Deploying Test Features …” in FMT_LIM.2.1 might be a little bit
misleading since the addressed features are no longer available (e.g. by disabling or removing the respective
functionality). Nevertheless the combination of FMT_LIM.1 and FMT_LIM.2 is introduced provide an optional approach to enforce the same policy. Note that the term “software” in item 4 of FMT_LIM.1.1 and

TOE is not requested to distinguish between these users within the role Manufacturer. The TOE may restrict
the ability to write the Initialization Data and the Prepersonalization Data by (i) allowing to write these data
only once and (ii) blocking the role Manufacturer at the end of the Phase 2. The IC Manufacturer may write
the Initialization Data which includes but are not limited to the IC Identifier as required by FAU_SAS.1. The
Initialization Data provides a unique identification of the IC which is used to trace the IC in the Phase 2 and
3 “personalization” but is not needed and may be misused in the Phase 4 “Operational Use”. Therefore the
external read access shall be blocked. The MRTD Manufacturer will write the Pre-personalization Data.

The TSF shall resist physical manipulation and physical probing to the TSF by responding automatically such that the SFRs are always enforced.
PP application note 53: The TOE will implement appropriate measures to continuously counter physical
manipulation and physical probing. Due to the nature of these attacks (especially manipulation) the TOE
can by no means detect attacks on all of its elements. Therefore, permanent protection against these attacks is required ensuring that the TSP could not be violated at any time. Hence, “automatic response”
means here (i) assuming that there might be an attack at any time and (ii) countermeasures are provided
at any time.

Table 12: Overview of the security functional requirements coverage.
The security objective OT.AC_Pers “Access Control for Personalization of logical MRTD” addresses the access control of the writing the logical MRTD. The write access to the logical MRTD data are defined by the
SFR FIA_UID.1, FIA_UAU.1, FDP_ACC.1 and FDP_ACF.1 in the same way: only the successfully authenticated
Personalization Agent is allowed to write the data of the groups EF.DG1 to EF.DG16 of the logical MRTD only
once. The SFR FMT_SMR.1 lists the roles (including Personalization Agent) and the SFR FMT_SMF.1 lists the
TSF management functions (including Personalization). The Personalization Agent handles the Document
Basic Access Keys according to the SFR FMT_MTD.1/KEY_WRITE as authentication reference data for Basic
Access Control.
The authentication of the terminal as Personalization Agent shall be performed by TSF according to SRF
FIA_UAU.4 and FIA_UAU.5. If the Personalization Terminal want to authenticate itself to the TOE by means
of the Terminal Authentication Protocol (after Chip Authentication) with the Personalization Agent Keys the
TOE will use TSF according to the FCS_RND.1 (for the generation of the challenge), FCS_CKM.1,
FCS_COP.1/SHA (for the derivation of the new session keys after Chip Authentication), and FCS_COP.1/SYM
and FCS_COP.1/MAC (for the ENC_MAC_Mode secure messaging), FCS_COP.1/SIG_VER (as part of the Terminal Authentication Protocol) and FIA_UAU.6 (for the re-authentication). If the Personalization Terminal
69 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
wants to authenticate itself to the TOE by means of the Symmetric Authentication Mechanism with Personalization Agent Key the TOE will use TSF according to the FCS_RND.1 (for the generation of the challenge)
and FCS_COP.1/SYM (to verify the authentication attempt). The session keys are destroyed according to
FCS_CKM.4 after use.
The SFR FMT_MTD.1/KEY_READ prevents read access to the secret key of the Personalization Agent Keys
and ensures together with the SFR FPT_EMSEC.1 the confidentially of these keys.
The security objective OT.Data_Int “Integrity of personal data” requires the TOE to protect the integrity of
the logical MRTD stored on the MRTD’s chip against physical manipulation and unauthorized writing. The
write access to the logical MRTD data is defined by the SFR FDP_ACC.1 and FDP_ACF.1 in the same way:
only the Personalization Agent is allowed to write the data in EF.DG1 to EF.DG16 of the logical MRTD
(FDP_ACF.1.2, rule 1) and terminals are not allowed to modify any of the data in EF.DG1 to EF.DG16 of the
logical MRTD (cf. FDP_ACF.1.4). The Personalization Agent must identify and authenticate themselves according to FIA_UID.1 and FIA_UAU.1 before accessing these data. The SFR FMT_SMR.1 lists the roles and
the SFR FMT_SMF.1 lists the TSF management functions.
The TOE supports the inspection system detect any modification of the transmitted logical MRTD data after
Chip Authentication. The authentication of the terminal as Personalization Agent shall be performed by TSF
according to SRF FIA_UAU.4, FIA_UAU.5 and FIA_UAU.6. The SFR FIA_UAU.6 and FDP_UIT.1 requires the
integrity protection of the transmitted data after chip authentication by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1 (for the generation of shared secret),
FCS_COP.1/SHA (for the derivation of the new session keys), and FCS_COP.1/SYM and FCS_COP.1/MAC for
the ENC_MAC_Mode secure messaging. The session keys are destroyed according to FCS_CKM.4 after use.
The SFR FMT_MTD.1/CAPK and FMT_MTD.1/KEY_READ requires that the Chip Authentication Key cannot
be written unauthorized or read afterwards.
The security objective OT.Sense_Data_Conf “Confidentiality of sensitive biometric reference data” is enforced by the Access Control SFP defined in FDP_ACC.1 and FDP_ACF.1 allowing the data of EF.DG3 and
EF.DG4 only to be read by successfully authenticated Extended Inspection System being authorized by a
validly verifiable certificate according FCS_COP.1/SIG_VER.
The SFR FIA_UID.1 and FIA_UAU.1 requires the identification and authentication of the inspection systems.
The SFR FIA_UAU.5 requires the successful Chip Authentication (CA) before any authentication attempt as
Extended Inspection System. During the protected communication following the CA the reuse of authentication data is prevented by FIA_UAU.4. The SFR FIA_UAU.6 and FDP_UCT.1 requires the confidentiality protection of the transmitted data after chip authentication by means of secure messaging implemented by
the cryptographic functions according to FCS_RND.1 (for the generation of the terminal authentication challenge), FCS_CKM.1 (for the generation of shared secret), FCS_COP.1/SHA (for the derivation of the new
session keys), and FCS_COP.1/SYM and FCS_COP.1/MAC for the ENC_MAC_Mode secure messaging. The
session keys are destroyed according to FCS_CKM.4 after use. The SFR FMT_MTD.1/CAPK and
FMT_MTD.1/KEY_READ requires that the Chip Authentication Key cannot be written unauthorized or read
afterwards.
To allow a verification of the certificate chain as in FMT_MTD.3 the CVCA’s public key and certificate as well
as the current date are written or update by authorized identified role as of FMT_MTD.1/CVCA_INI,
FMT_MTD.1/CVCA_UPD and FMT_MTD.1/DATE.
The security objective OT.Identification “Identification and Authentication of the TOE” address the storage
of the IC Identification Data uniquely identifying the MRTD’s chip in its non-volatile memory. This will be
ensured by TSF according to SFR FAU_SAS.1.
The SFR FMT_MTD.1/INI_ENA allows only the Manufacturer to write Initialization Data and Pre-personalization Data (including the Personalization Agent key). The SFR FMT_MTD.1/INI_DIS allows the Personalization Agent to disable Initialization Data if their usage in the phase 4 “Operational Use” violates the security
objective OT.Identification.

cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
The security objective OT.Chip_Auth_Proof “Proof of MRTD’s chip authenticity” is ensured by the Chip Authentication Protocol provided by FIA_API.1 proving the identity of the TOE. The Chip Authentication Protocol defined by FCS_CKM.1 is performed using a TOE internally stored confidential private key as required
by FMT_MTD.1/CAPK and FMT_MTD.1/KEY_READ. The Chip Authentication Protocol [TR-03110] requires
additional TSF according to FCS_COP.1/SHA (for the derivation of the session keys), FCS_COP.1/SYM and
FCS_COP.1/MAC (for the ENC_MAC_Mode secure messaging). It is also achieved by the optional Active Authentication defined by FIA_API.1/AA and FMT_MTD.1/AAPK.
The security objective OT.Prot_Abuse-Func “Protection against Abuse of Functionality” is ensured by the
SFR FMT_LIM.1 and FMT_LIM.2 which prevent misuse of test functionality of the TOE or other features
which may not be used after TOE Delivery.
The security objective OT.Prot_Inf_Leak “Protection against Information Leakage” requires the TOE to protect confidential TSF data stored and/or processed in the MRTD’s chip against disclosure

by measurement and analysis of the shape and amplitude of signals or the time between events
found by measuring signals on the electromagnetic field, power consumption, clock, or I/O lines
which is addressed by the SFR FPT_EMSEC.1,

by forcing a malfunction of the TOE which is addressed by the SFR FPT_FLS.1 and FPT_TST.1, and/or

by a physical manipulation of the TOE which is addressed by the SFR FPT_PHP.3.
The security objective OT.Prot_Phys-Tamper “Protection against Physical Tampering” is covered by the SFR
FPT_PHP.3.
The security objective OT.Prot_Malfunction “Protection against Malfunctions” is covered by (i) the SFR
FPT_TST.1 which requires self tests to demonstrate the correct operation and tests of authorized users to
verify the integrity of TSF data and TSF code, and (ii) the SFR FPT_FLS.1 which requires a secure state in case
of detected failure or operating conditions possibly causing a malfunction.

Table 13: Overview of the dependencies between the SFR of the TOE.
Justification for non-satisfied dependencies between the SFR for TOE:

No. 1: The hash algorithm required by the SFR FCS_COP.1/SHA does not need any key material.
Therefore neither a key generation (FCS_CKM.1) nor an import (FDP_ITC.1/2) is necessary.

No. 2: The access control TSF according to FDP_ACF.1 uses security attributes which are defined
during the personalization and are fixed over the whole life time of the TOE. No management of
these security attribute (i.e. SFR FMT_MSA.1 and FMT_MSA.3) is necessary here.

No. 3: The SFR FDP_UCT.1 and FDP_UIT.1 require the use secure messaging between the MRTD and
the GIS. There is no need for the SFR FTP_ITC.1, e.g. to require this communication channel to be
logically distinct from other communication channels since there is only one channel. Since the TOE
does not provide a direct human interface a trusted path as required by FTP_TRP.1 is not applicable
here.
6.4.3 Security Assurance Requirements Rationale
The EAL4 was chosen to permit a developer to gain maximum assurance from positive security engineering
based on good commercial development practices which, though rigorous, do not require substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at which it is likely to be economically
feasible to retrofit to an existing product line. EAL4 is applicable in those circumstances where developers
or users require a moderate to high level of independently assured security in conventional commodity
TOEs and are prepared to incur sensitive security specific engineering costs.
The selection of the component ALC_DVS.2 provides a higher assurance of the security of the MRTD’s development and manufacturing especially for the secure handling of the MRTD’s material.
The selection of the component AVA_VAN.5 provides a higher assurance of the security by vulnerability
analysis to assess the resistance to penetration attacks performed by an attacker possessing a high attack
potential. This vulnerability analysis is necessary to fulfill the security objectives OT.Sens_Data_Conf and
OT.Chip_Auth_Proof.
The component ALC_DVS.2 has no dependencies.
The component AVA_VAN.5 has the following dependencies:

ADV_ARC.1 Security architecture description

ADV_FSP.2 Security-enforcing functional specification

ADV_TDS.3 Basic modular design

ADV_IMP.1 Implementation representation of the TSF

cv act ePasslet2.1/MRTD-EACv1-BAC Security Target

AGD_OPE.1 Operational user guidance

AGD_PRE.1 Preparative procedures
All of these are met or exceeded in the EAL4 assurance package.
6.4.4 Security Requirements – Mutual Support and Internal Consistency
The following part of the security requirements rationale shows that the set of security requirements for
the TOE consisting of the security functional requirements (SFRs) and the security assurance requirements
(SARs) together form a mutually supportive and internally consistent whole.
The analysis of the TOE´s security requirements with regard to their mutual support and internal consistency
demonstrates:
The dependency analysis in section 6.3.2 Dependency Rationale for the security functional requirements
shows that the basis for mutual support and internal consistency between all defined functional requirements is satisfied. All dependencies between the chosen functional components are analyzed, and nonsatisfied dependencies are appropriately explained.
The assurance class EAL4 is an established set of mutually supportive and internally consistent assurance
requirements. The dependency analysis for the sensitive assurance components in section 6.3.3 Security
Assurance Requirements Rationale shows that the assurance requirements are mutually supportive and
internally consistent as all (sensitive) dependencies are satisfied and no inconsistency appears.
Inconsistency between functional and assurance requirements could only arise if there are functional-assurance dependencies which are not met, a possibility which has been shown not to arise in sections 6.3.2
Dependency Rationale and 6.3.3 Security Assurance Requirements Rationale. Furthermore, as also discussed in section 6.3.3 Security Assurance Requirements Rationale, the chosen assurance components are
adequate for the functionality of the TOE. So the assurance requirements and security functional requirements support each other and there are no inconsistencies between the goals of these two groups of security requirements.

7.1.8 TSF_OS: Javacard OS Security Functionalities
The Javacard operation system (part of the TOE) features the following Security Functionalities. The exact
description can be found in the Javacard OS security target [ST_JCOP]; the realization is partly based on the
security functionalities of the certified cryptographic library and the certified IC platform:

Enforcement of access control (SF.AccessControl)

Audit functionality (SF.Audit)

Cryptographic key management (SF.CryptoKey)

Cryptographic operations (SF.CryptoOperation)

Identification and authentication (SF.I&A)

Secure management of TOE resources (SF.SecureManagement)
83 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target

Transaction management (SF.Transaction)
Since the applet layer of the TOE is based on the Javacard OS, the realization of all TOE security functionalities and thus the fulfillment of all SFRs has dependencies to TSF_OS. The following items list all SFRs where
TSF_OS has an impact above this level:

FCS_CKM.1: FCS_CKM.1.1 requires that the TSF shall generate cryptographic keys in accordance
with a specified cryptographic key generation algorithm and specified cryptographic key sizes. This
is realized within TSF_OS.

FCS_CKM.4.1 requires that the TSF shall destroy cryptographic keys in accordance with a specified
cryptographic key destruction method. This is realized in the security functionality provided by
TSF_OS.

FCS_COP.1.1/SHA: FCS_COP.1.1/SHA requires that the TSF shall perform hashing in accordance with
a specified cryptographic algorithm. This is realized within TSF_OS.

FCS_COP.1.1/SYM requires that the TSF shall perform secure messaging – encryption and decryption in accordance with a specified cryptographic algorithm: AES in CBC mode and cryptographic
key size 128, 192 or 256 bit that meets the following: FIPS 197 and TR-03110. This is realized within
TSF_OS.

FCS_COP.1.1/MAC requires that the TSF shall perform secure messaging – message authentication
code in accordance with a specified cryptographic algorithm: AES-CMAC and cryptographic key size
128, 192 or 256 bit that meets the following: TR-03110. This is realized within TSF_OS.

FCS_COP.1/SIG_VER requires that the TSF shall perform digital signature verification in accordance
with a specified cryptographic algorithm: ECDSA with SHA-1, SHA-224 or SHA-256 and cryptographic
key sizes of 160, 192, 224, 256 and 320 bit with specified curves that meet the following:
ISO15946This is realized within TSF_Crypto and TSF_OS

FCS_RND.1: FCS_RND.1.1 requires that the TSF shall provide a mechanism to generate random
numbers that meet the AIS 20 Class DRG3 quality metric. This is realized within TSF_OS.

FMT_LIM.1 requires that the TSF shall be designed in a manner that limits their capabilities so that
in conjunction with “Limited availability (FMT_LIM.2)” the following policy is enforced: Deploying
Test Features after TOE Delivery does not allow (1.) User Data to be manipulated, (2.) sensitive User
Data (EF.DG3 and EF.DG4) to be disclosed, (3.) TSF data to be disclosed or manipulated, (4.) software
to be reconstructed, and (5.) substantial information about construction of TSF to be gathered
which may enable other attacks. This is realized by TSF_OS.

FMT_LIM.2 requires that the TSF shall be designed in a manner that limits their availability so that
in conjunction with “Limited capabilities (FMT_LIM.1)” the following policy is enforced: Deploying
Test Features after TOE Delivery does not allow (1.) User Data to be manipulated, (2.) sensitive User
Data (EF.DG3 and EF.DG4) to be disclosed, (3.), TSF data to be disclosed or manipulated (4.), software to be reconstructed, and (5.) substantial information about construction of TSF to be gathered
which may enable other attacks. This is realized by TSF_OS.

FMT_MTD.1.1/INI_ENA requires that the TSF shall restrict the ability to write the Initialization Data
and Prepersonalization Data to the Manufacturer. This is realized by TSF_OS.

FMT_MTD.1.1/INI_DIS requires that the TSF shall restrict the ability to disable read access for users
to the Initialization Data to the Personalization Agent. This is realized by TSF_OS.

FMT_MTD.1.1/KEY_READ requires that the TSF shall restrict the ability to read the (1.) Document
Basic Access Keys, the (2.) Chip Authentication Private Key, the (3.) Personalization Agent Keys and
the (4.) optional Active Authentication Key to none. This is realized by TSF_OS.


or timing during command execution in excess of non-useful information enabling access to Personalization Agent Keys and Chip Authentication Private Key. FPT_EMSEC.1.2 requires that the TSF
84 of 97
cv act ePasslet2.1/MRTD-EACv1-BAC Security Target
shall ensure any users are unable to use the following interface: smart card circuit contacts or contactless interface to gain access to Personalization Agent Key(s), the optional Active Authentication
Key and Chip Authentication Private Key. This is mainly realized by appropriate measures in TSF_OS
together with the strict following of the security implementation guidelines of the Javacard platform.

FPT_FLS.1.1 requires that the TSF shall preserve a secure state when the following types of failures
occur: (1) exposure to out-of-range operating conditions where therefore a malfunction could occur, and (2) failure detected by TSF according to FPT_TST.1. This is realized within TSF_OS (together
with TSF_Integrity).

FPT_TST.1.1 requires that the TSF shall run a suite of self tests during initial start-up to demonstrate
the correct operation of the TSF. FPT_TST.1.2 requires that the TSF shall provide authorised users
with the capability to verify the integrity of TSF data. FPT_TST.1.3 requires that the TSF shall provide
authorised users with the capability to verify the integrity of stored TSF executable code. This all is
realized by TSF_OS, in parts due to the characteristics of the hardware platform.

FPT_PHP.3.1 requires that the TSF shall resist physical manipulation and physical probing to the TSF
by responding automatically such that the SFRs are always enforced. This all is realized by TSF_OS,
in parts due to the characteristics of the hardware platform.

Glossary
Active authentication
Security mechanism defined in [ICAODoc] by which means the MTRD’s chip
proves and the inspection system verifies the identity and authenticity of the
MTRD’s chip as part of a genuine MRTD issued by a known State of organization.
AES
The AES (Advanced Encryption Standard) has been defined as a standard for
symmetric data encryption. It is a block cipher with a block length of 128 bit and
key lengths of 128, 192 and 256 bit.
Application note
Optional informative part of the PP containing additional supporting information that is considered relevant or useful for the construction, evaluation, or
use of the TOE.
Asymmetric cipher
Encryption procedures employing two different keys (in contrast to a symmetric
cipher): one publicly known (public key) for data encryption and one key only
known to the message receiver (private key) for decryption.
Audit records
Write-only-once non-volatile memory area of the MRTDs chip to store the Initialization Data and Pre-personalization Data.

the MTRD’s chip proves and the inspection system protects their communication by means of secure messaging.
Basic access keys
Pair of symmetric Triple-DES keys used for secure messaging with encryption
(key KENC) and message authentication (key KMAC) of data transmitted between the MRTD’s chip and the inspection system [ICAODoc]. It is drawn from
the printed MRZ of the passport book to authenticate an entity able to read the
printed MRZ of the passport book.

comprises a larger field and also includes problems like authentication or digital
signatures.

Current date
The maximum of the effective dates of valid CVCA, DV and domestic Inspection
System certificates known to the TOE. It is used the validate card verifiable certificates.
CVCA link certificate
Certificate of the new public key of the Country Verifying Certification
Authority signed with the old public key of the Country Verifying
Certification Authority where the certificate effective date for the new key is
before the certificate expiration date of the certificate for the old key.
DES
(Data Encryption Standard) symmetric 64 bit block cipher, which was developed
(first under the name Lucifer) by IBM. The key length is 64 bit of which 8 bit serve
for a parity check. DES is the classic among the encryption algorithms, which
nevertheless is no longer secure due to its insufficient key length. Alternatives
are Triple-DES or the successor AES.
Digital certificate
A data set that identifies the certification authority issuing it, identifies its
owner, contains the ower's public key, identifies its operational period, and is
digitally signed by the certification authority issuing it.
Digital signature
The counterpart of a handwritten signature for documents in digital format. A
digital signature grants authentication, integrity, and non-repudiation. These
features are achieved by using asymmetric procedures.
Document verifier
Certification authority creating the Inspection System Certificates and
managing the authorization of the Extended Inspection Systems for the
sensitive data of the MRTD in the limits provided by the issuing States or
Organizations
EAC
Extended access control. Security mechanism identified in [ICAODoc] by which
means the MTRD’s chip (i) verifies the authentication of the inspection systems
authorized to read the optional biometric reference data, (ii) controls the access
to the optional biometric reference data and (iii) protects the confidentiality and
integrity of the optional biometric reference data during their transmission to
the inspection system by secure messaging.
ECC
(Elliptic Curve Cryptography) class of procedures providing an attractive alternative for the probably most popular asymmetric procedure, the RSA algorithm.
Elliptic curves
A mathematical construction, in which a part of the usual operations applies,
and which has been employed successfully in cryptography since 1985.
Fingerprint (digital)
Checksum that can be used to easily determine the correctness of a key without
having to compare the entire key. This is often done by comparing the hash values after application of a hash function.
Hash function
A function which forms the fixed-size result (the hash value) from an arbitrary
amount of data (which is the input). These functions are used to generate the
electronic equivalent of a fingerprint. The significant factor is that it must be
impossible to generate two entries which lead to the same hash value (so called
collisions) or even to generate a matching message for a defined hash value.
Common hash functions are RIPEMD-160 and SHA-1, each having hash values
with a length of 160 bit as well as the MD5, which is still often used today having
a hash value length of 128 bit.
Inspection system
A technical system used by the border control officer of the receiving State (i)
examining an MRTD presented by the traveller and verifying its authenticity and
(ii) verifying the traveller as MRTD holder.

Integrity
The test on the integrity of data is carried out by checking messages for changes
during the transmission by the receiver. Common test procedures employ Hashfunctions, MACs (Message Authentication Codes) or – with additional functionality – digital signatures.
Javacard
A smart card with a Javacard operation system.
Key exchange
The use of symmetric cipher procedures requires that two communication partners decide on one joint key only known to themselves. The difficulty is that for
the exchange of such information usually only partially secure channels exist.
Additionally, protocols for key exchange must be prepared in such a way that
only those pieces of information are exchanged which do not lead to knowledge
of the real secret (the key). The most popular protocol of that type is diffieHellman, whose presentation in 1976 can be regarded as the birth of public key
cryptography.
LDS
Logical data structure. The collection of groupings of data elements stored in
the optional capacity expansion technology, defined in [ICAODoc].
MAC
Algorithm that expands the message by means of a secret key by special redundant pieces of information, which are stored or transmitted together with the
message. To prevent an attacker from targeted modification of the attached redundancy, requires its protection in a suitable way.
MRTD
Machnine-readable travel document. Official document issued by a State or Organization which is used by the holder for international travel (e.g. passport,
visa, official document of identity) and which contains mandatory visual (eye
readable) data and a separate mandatory data summary, intended for global
use, reflecting essential data elements capable of being machine read.
MRZ
Fixed dimensional area located on the front of the MRTD or MRP Data Page or,
in the case of the TD1, the back of the MRTD, containing mandatory and optional
data for machine reading using OCR methods.
Non-repudiation
One of the objectives in the employment of digital signatures. It describes the
fact that the sender of a message is prevented from denying the preparation of
the message. The problem cannot be simply solved with cryptographic routines,
but the entire environment needs to be considered and respective framework
conditions need to be provided by pertinent laws.
Passive authentication
(i) verification of the digital signature of the Document Security Object and (ii)
comparing the hash values of the read LDS data fields with the hash values contained in the Document Security Object.
Passphrase
A long, but memorable character sequence (e.g. short sentences with punctuation) which should replace passwords as they offer more security.
Password
A secret character sequence whose knowledge is to serve as a replacement for
the authentication of a participant. A password is usually short to really ensure
that an attacker cannot guess the password by trial and error.
Personalization
The process by which the portrait, signature and biographical data are applied
to the document.
Personalization agent
The agent acting on the behalf of the issuing State or organisation to personalize
the MRTD for the holder by (i) establishing the identity the holder for the biographic data in the MRTD, (ii) enrolling the biometric reference data of the
MRTD holder i.e. the portrait, the encoded finger image(s) or (ii) the encoded
iris image(s) and (iii) writing these data on the physical and logical MRTD for the
holder.

Protection Profile
Private key
Secret key only known to the receiver of a message, which is used in asymmetric
ciphers for encryption or generation of digital signatures.
Pseudo random number
Many cryptographic mechanisms require random numbers (e.g. in key generation). The problem, however, is that it is difficult to implement true random
numbers in software. Therefore, so called pseudo-random number generators
are used, which then should be initialized with a real random element (the so
called seed).
Public key
Publicly known key in an asymmetric cipher which is used for encryption and
verification of digital signatures.
Public key infrastructure (PKI)
Combination of hardware and software components, policies, and different procedures used to manage digital certificates.
Random numbers
Many cryptographic algorithms or protocols require a random element, mostly
in form of a random number, which is newly generated in each case. In these
cases, the security of the procedure depends in part on the suitability of these
random numbers. As the generation of real random numbers within computers
still imposes a problem (a source for real random events can in fact only be
gained by exact observation of physical events, which is not easy to realize for a
software), so called pseudo random numbers are used instead.
Secure messaging
Secure messaging using encryption and message authentication code according
to ISO/IEC 7816-4.
SFR
Security functional requirement.
Skimming
Imitation of the inspection system to read the logical MRTD or parts of it via the
contactless communication channel of the TOE without knowledge of the
printed MRZ data.
Smart card
A smart card is a chip card which contains an internal micro controller with CPU,
volatile (RAM) and non-volatile (ROM, EEPROM) memory, i.e. which can carry
out its own calculations in contrast to a simple storage card. Sometimes a smart
card has a numerical coprocessor (NPU) to execute public key algorithms efficiently. Smart cards have all of their functionality comprised on a single chip (in
contrast to chip cards, which contain several chips wired to each other). Therefore, such a smart card is ideal for use in cryptography as it is almost impossible
to manipulate its internal processes.
SOD
Document Security Object (stored in EF.SOD). A RFC3369 CMS Signed Data
Structure, signed by the Document Signer (DS). Carries the hash values of the
LDS Data Groups. It is stored in the MRTD’s chip. It may carry the Document
Signer Certificate (CDS).
ST

Stream cipher
Symmetric encryption algorithm which processes the plaintext bit-by-bit or
byte-by-byte. The other usually employed class of procedures comprises so
called block cipher.
Symmetric cipher
Encryption procedure using the same key for enciphering and deciphering (or,
in which these two keys can simply be derived from each other). One distinguishes between block ciphers processing plaintext in blocks of fixed length
(mostly 64 or 128 bit) and stream ciphers working on the basis of single characters.
