Common Criteria Protection Profile 1.3.0, 20 th January 2012

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE

Foreword

This ‘Protection Profile — Machine Readable Travel Document with ICAO Application (EAC

PP), Extended Access Control with PACE’ is issued by Bundesamt für Sicherheit in der

Informationstechnik, Germany.

Throughout this document, the term PACE refers to PACE v2.

The ICAO Technical Report "Supplemental Access Control" [4] describes how to migrate from the current access control mechanism, Basic Access Control, to PACE v2, a new cryptographically strong access control mechanism that is initially provided supplementary to Basic Access Control:

"There is no straightforward way to strengthen Basic Access Control as its limitations are

inherent to the design of the protocol based on symmetric (“secret key”) cryptography. A cryptographically strong access control mechanism must (additionally) use asymmetric (“public key”) cryptography.

This Technical Report specifies PACE as an access control mechanism that is supplemental to

Basic Access Control. PACE MAY be implemented in addition to Basic Access Control, i.e.

States MUST NOT implement PACE without implementing Basic Access Control if global interoperability is required.

Inspection Systems SHOULD implement and use PACE if provided by the MRTD chip.

Note: Basic Access Control will remain the “default” access control mechanism for globally interoperable machine readable travel documents as long as Basic Access Control provides sufficient security. Basic Access Control may however become deprecated in the future. In this case PACE will become the default access control mechanism.

The inspection system SHALL use either BAC or PACE but not both in the same session."

Within the migration period, some developers will have to implement their products to functionally support both, PACE and Basic Access Control (BAC), i.e. Supplemental Access

Control (SAC). However, any product using BAC will not be conformant to the current PP; i.e. a product implementing the TOE may functionally use BAC, but, while performing BAC, they are acting outside of security policy defined by the current PP. Therefore, organizations being responsible for the operation of inspection systems shall be aware of this context.

TOE usage and security features for operational use

A State or Organisation issues travel documents to be used by the holder for international travel. The traveller presents a travel document to the inspection system to prove his or her identity. The travel document in context of this protection profile 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 travel document’s chip according to LDS in case of contactless machine reading. The authentication of the traveller is based on (i) the possession of a valid travel document personalised for a holder with the claimed identity as given on the biographical data page and (ii) biometrics using the reference data stored in the travel document. The issuing

State or Organisation ensures the authenticity of the data of genuine travel documents. The receiving State trusts a genuine travel document of an issuing State or Organisation.

For this protection profile the travel document is viewed as unit of

(i) the physical part of the travel document in form of paper and/or plastic and chip. It presents visual readable data including (but not limited to) personal data of the travel document holder

(a) the biographical data on the biographical data page of the travel document surface,

(b) the printed data in the Machine Readable Zone (MRZ) and

(c) the printed portrait.

(ii) the logical travel document as data of the travel document holder stored according to the

Logical Data Structure as defined in [6] as specified by ICAO on the contact based or contactless integrated circuit. It presents contact based / contactless readable data including

(but not limited to) personal data of the travel document holder

(a) the digital Machine Readable Zone Data (digital MRZ data, EF.DG1),

(b) the digitized portraits (EF.DG2),

(c) the biometric reference data of finger(s) (EF.DG3) or iris image(s) (EF.DG4) or both 1

(d) the other data according to LDS (EF.DG5 to EF.DG16) and

(e) the Document Security Object (SOD).

The issuing State or Organisation implements security features of the travel document to maintain the authenticity and integrity of the travel document and their data. The physical part of the travel document and the travel document’s chip are identified by the Document Number.

The physical part of the travel document is protected by physical security measures (e.g. watermark, security printing), logical (e.g. authentication keys of the travel document’s chip) and organisational security measures (e.g. control of materials, personalisation procedures) [6].

These security measures can include the binding of the travel document’s chip to the travel document.

These biometric reference data are optional according to [6]. This PP assumes that the issuing State or

Organisation uses this option and protects these data by means of extended access control.

1.3.0, 20 th January 2012 Common Criteria Protection Profile

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE

The logical travel document is protected in authenticity and integrity by a digital signature created by the document signer acting for the issuing State or Organisation and the security features of the travel document’s chip.

The ICAO defines the baseline security methods Passive Authentication and the optional advanced security methods Basic Access Control to the logical travel document, Active

Authentication of the travel document’s chip, Extended Access Control to and the Data

Encryption of sensitive biometrics as optional security measure in the ICAO Doc 9303 [6], and

Password Authenticated Connection Establishment [4]. The Passive Authentication Mechanism is performed completely and independently of the TOE by the TOE environment.

This protection profile addresses the protection of the logical travel document (i) in integrity by write-only-once access control and by physical means, and (ii) in confidentiality by the

Extended Access Control Mechanism. This protection profile addresses the Chip

Authentication Version 1 described in [5] as an alternative to the Active Authentication stated in [6].

If BAC is supported by the TOE, the travel document has to be evaluated and certified separately. This is due to the fact that [8] does only consider extended basic attack potential to the Basic Access Control Mechanism (i.e. AVA_VAN.3).

The confidentiality by Password Authenticated Connection Establishment (PACE) is a mandatory security feature of the TOE. The travel document shall strictly conform to the

‘Common Criteria Protection Profile Machine Readable Travel Document using Standard

Inspection Procedure with PACE (PACE PP)’ [7]. Note that [7] considers high attack potential.

For the PACE protocol according to [4], the following steps shall be performed:

(i) the travel document's chip encrypts a nonce with the shared password, derived from the

MRZ resp. CAN data and transmits the encrypted nonce together with the domain parameters to the terminal.

(ii) The terminal recovers the nonce using the shared password, by (physically) reading the

MRZ resp. CAN data.

(iii) The travel document's chip and terminal computer perform a Diffie-Hellmann key agreement together with the ephemeral domain parameters to create a shared secret.

Both parties derive the session keys K

MAC

and K

ENC

from the shared secret.

(iv) Each party generates an authentication token, sends it to the other party and verifies the received token.

After successful key negotiation the terminal and the travel document's chip provide private communication (secure messaging) [5], [4].

The protection profile requires the TOE to implement the Extended Access Control as defined in [5]. The Extended Access Control consists of two parts (i) the Chip Authentication Protocol

Version 1 and (ii) the Terminal Authentication Protocol Version 1 (v.1). The Chip

Authentication Protocol v.1 (i) authenticates the travel document’s chip to the inspection

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE system and (ii) establishes secure messaging which is used by Terminal Authentication v.1 to protect the confidentiality and integrity of the sensitive biometric reference data during their transmission from the TOE to the inspection system. Therefore Terminal Authentication v.1 can only be performed if Chip Authentication v.1 has been successfully executed. The

Terminal Authentication Protocol v.1 consists of (i) the authentication of the inspection system as entity authorized by the receiving State or Organisation through the issuing State, and (ii) an access control by the TOE to allow reading the sensitive biometric reference data only to successfully authenticated authorized inspection systems. The issuing State or Organisation authorizes the receiving State by means of certification the authentication public keys of

Document Verifiers who create Inspection System Certificates.

TOE life-cycle

The TOE life-cycle is described in terms of the four life-cycle phases. (With respect to the [9], the TOE life-cycle the life-cycle is additionally subdivided into 7 steps.)

Phase 1 “Development”

(Step1) 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.

(Step2) The software developer 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 ePassport 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 is securely delivered to the IC manufacturer. The IC Embedded Software in the non-volatile programmable memories, the ePassport application and the guidance documentation is securely delivered to the travel document manufacturer.

Phase 2 “Manufacturing”

(Step3) In a first step the TOE integrated circuit is produced containing the travel document’s chip Dedicated Software and the parts of the travel document’s chip Embedded Software in the non-volatile non-programmable memories (ROM). The IC manufacturer writes the IC

Identification Data onto the chip to control the IC as travel document material during the IC manufacturing and the delivery process to the travel document manufacturer. The IC is securely delivered from the IC manufacture to the travel document manufacturer.

If necessary the IC manufacturer adds the parts of the IC Embedded Software in the nonvolatile programmable memories (for instance EEPROM).

(Step4 optional) The travel document manufacturer combines the IC with hardware for the contact based / contactless interface in the travel document unless the travel document consists of the card only.

1.3.0, 20 th January 2012 Common Criteria Protection Profile

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE

(Step5) The travel document manufacturer (i) adds the IC Embedded Software or part of it in the non-volatile programmable memories (for instance EEPROM or FLASH) if necessary, (ii) creates the ePassport application, and (iii) equips travel document’s chips with prepersonalization Data.

Application Note 1: Creation of the application implies:

°

For file based operating systems: the creation of MF and ICAO.DF

°

For JavaCard operating systems: the Applet instantiation.

The pre-personalised travel document together with the IC Identifier is securely delivered from the travel document manufacturer to the Personalisation Agent. The travel document manufacturer also provides the relevant parts of the guidance documentation to the

Personalisation Agent.

Phase 3 “Personalisation of the travel document”

(Step6) The personalisation of the travel document includes (i) the survey of the travel document holder’s biographical data, (ii) the enrolment of the travel document holder biometric reference data (i.e. the digitized portraits and the optional biometric reference data), (iii) the personalization of the visual readable data onto the physical part of the travel document, (iv) the writing of the TOE User Data and TSF Data into the logical travel document and (v) 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 (EF.DG1), (ii) the digitized portrait (EF.DG2), and (iii) the Document security object.

The signing of the Document security object by the Document signer [6] finalizes the personalisation of the genuine travel document for the travel document holder. The personalised travel document (together with appropriate guidance for TOE use if necessary) is handed over to the travel document holder for operational use.

Application note 2: The TSF data (data created by and for the TOE, that might affect the operation of the TOE; cf. [1] §92) comprise (but are not limited to) the Personalisation Agent

Authentication Key(s), the Terminal Authentication trust anchor, the effective date and the

Chip Authentication Private Key.

Application note 3: This protection profile distinguishes between the Personalisation Agent as entity known to the TOE and the Document Signer as entity in the TOE IT environment signing the Document security object as described in [6]. This approach allows but does not enforce the separation of these roles.

Phase 4 “Operational Use”

(Step7) The TOE is used as a travel document'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 Organisation and can be used according to the security policy of the issuing

State but they can never be modified.

Application note 4: The intention of the PP is to consider at least the phases 1 and parts of

Common Criteria Protection Profile 1.3.0, 20 th January 2012

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE 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 Organisation. In this case the national body of the issuing State or Organisation is responsible for these specific production steps.

Note that the personalisation process and its environment may depend on specific security needs of an issuing State or Organisation. 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. Therefore, the Security Target has to outline the split up of P.Manufact, P.Personalisation and the related security objectives into aspects relevant before vs. after TOE delivery.

Some production steps, e.g. Step 4 in Phase 2 may also take place in the Phase 3.

255

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 travel document, nevertheless these parts are not inevitable for the secure operation of the TOE.

Introduction

290

Assets

The assets to be protected by the TOE include the User Data on the travel document’s chip, user data transferred between the TOE and the terminal, and travel document tracing data from the claimed PACE PP [7], chap 3.1.

295

300

Logical travel document sensitive User Data

Sensitive biometric reference data (EF.DG3, EF.DG4)

Application note 5: Due to interoperability reasons the ‘ICAO Doc 9303’ [6] requires that

Basic Inspection Systems may have access to logical travel document data DG1, DG2, DG5 to

DG16. The TOE is not in certified mode, if it is accessed using BAC [6]. Note that the BAC mechanism cannot resist attacks with high attack potential (cf. [8]). If supported, it is therefore recommended to used PACE instead of BAC. If nevertheless BAC has to be used, it is recommended to perform Chip Authentication v.1

as this mechanism is resistant to high potential attacks

A sensitive asset is the following more general one.

305

310

Authenticity of the travel document’s chip

The authenticity of the travel document’s chip personalised by the issuing State or Organisation for the travel document holder is used by the traveller to prove his possession of a genuine travel document.

Due to strict conformance to PACE PP, this PP also includes all assets listed in [7], chap 3.1, namely the primary assets user data stored on the TOE (object 1), user data transferred between the TOE and the terminal connected (object 2), travel document tracing data (object 3), and the secondary assets accessibility to the TOE functions and data only for authorised subjects

(object 4) Genuineness of the TOE (object 5), TOE intrinsic secret cryptographic keys (object

6), TOE intrinsic non secret cryptographic material (object 7), and travel document communication establishment authorisation data (object 8). Due to identical names and definitions these are not repeated here.

315

Subjects

This protection profile considers the following subjects additionally to those defined PACE PP

[7]:

Common Criteria Protection Profile 1.3.0, 20 th January 2012

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE

320

Country Verifying Certification Authority

The Country Verifying Certification Authority (CVCA) enforces the privacy policy of the issuing State or Organisation with respect to the protection of sensitive biometric reference data stored in the travel document. 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.

325

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 travel document in the limits provided by the issuing

States or Organisations in the form of the Document Verifier Certificates.

330

Terminal

A terminal is any technical system communicating with the TOE either through the contact interface or through the contactless interface.

335

340

345

Inspection system (IS)

A technical system used by the border control officer of the receiving State (i) examining an travel document presented by the traveller and verifying its authenticity and (ii) verifying the traveller as travel document holder.

The Extended Inspection System (EIS) performs the Advanced Inspection Procedure (figure

1) and therefore (i) contains a terminal for the communication with the travel document’s chip,

(ii) implements the terminals part of PACE and/or BAC; (iii) gets the authorization to read the logical travel document either under PACE or BAC by optical reading the travel document providing this information. (iv) implements the Terminal Authentication and Chip

Authentication Protocols both Version 1 according to [5] and (v) is authorized by the issuing

State or Organisation through the Document Verifier of the receiving State to read the sensitive biometric reference data. Security attributes of the EIS are defined by means of the Inspection

System Certificates. BAC may only be used if supported by the TOE. If both PACE and BAC are supported by the TOE and the BIS, PACE must be used.

Application note 6: For definition of Basic Inspection System (BIS) resp. Basic Inspection

System with PACE (BIS-PACE) see PACE PP [7].

figure 1: Advanced Inspection Procedure

Attacker

Additionally to the definition from PACE PP [7], chap 3.1 the definition of an attacker is refined as followed: A threat agent trying (i) to manipulate the logical travel document without authorization, (ii) to read sensitive biometric reference data (i.e. EF.DG3, EF.DG4), (iii) to forge a genuine travel document, or (iv) to trace a travel document.

Application note 7: An impostor is attacking the inspection system as TOE IT environment independent on using a genuine, counterfeit or forged travel document. Therefore the impostor may use results of successful attacks against the TOE but the attack itself is not relevant for the

TOE.

This PP includes all subjects from the PACE Protection Profile [7], chap 3.1, namely

Manufacturer, Personalisation Agent, Basic Inspection System (with PACE), Document Signer

(DS), and Country Signing Certification Authority (CSCA), Travel Document Holder and

Travel Document Presenter (traveller). Due to identical definitions and names they are not repeated here.

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.

370

375

A.Insp_Sys Inspection Systems for global interoperability

The Extended Inspection System (EIS) for global interoperability (i) includes the Country

Signing CA Public Key and (ii) implements the terminal part of PACE [4] and/or BAC [8].

BAC may only be used if supported by the TOE. If both PACE and BAC are supported by the

TOE and the IS, PACE must be used. The EIS reads the logical travel document under PACE or BAC and performs the Chip Authentication v.1 to verify the logical travel document and establishes secure messaging. EIS supports the Terminal Authentication Protocol v.1 in order to ensure access control and is authorized by the issuing State or Organisation through the

Document Verifier of the receiving State to read the sensitive biometric reference data.

Justification:

The assumption A.Insp_Sys does not confine the security objectives of the [7] as it repeats the requirements of P.Terminal and adds only assumptions for the Inspection Systems for handling the the EAC functionality of the TOE.

380

385

390

395

A.Auth_PKI PKI for Inspection Systems

The issuing and receiving States or Organisations 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 Organisations 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 Organisations. The issuing States or

Organisations distribute the public keys of their Country Verifying Certification Authority to their travel document’s chip.

Justification:

This assumption only concerns the EAC part of the TOE. The issuing and use of card verifiable certificates of the Extended Access Control is neither relevant for the PACE part of the TOE nor will the security objectives of the [7] be restricted by this assumption. For the EAC functionality of the TOE the assumption is necessary because it covers the pre-requisite for performing the Terminal Authentication Protocol Version 1.

This PP includes the assumption from the PACE PP [7], chap 3.4, namely A.Passive_Auth.

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE 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.

The TOE in collaboration with its IT environment shall avert the threats as specified below.

405

410

415

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 travel document’s chip.

The attack T.Read_Sensitive_Data is similar to the threat T.Skimming (cf. [8]) in respect of the attack path (communication interface) and the motivation (to get data stored on the travel document’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 the PACE

Password) and therefore the possible attack methods. Note, that the sensitive biometric reference data are stored only on the travel document’s chip as private sensitive personal data whereas the MRZ data and the portrait are visually readable on the physical part of the travel document as well.

Threat agent: having high attack potential, knowing the PACE Password, being in possession of a legitimate travel document

Asset: confidentiality of logical travel document sensitive user data (i.e. biometric reference)

420

425

430

435

T.Counterfeit

Counterfeit of travel document chip data

Adverse action: An attacker with high attack potential produces an unauthorized copy or reproduction of a genuine travel document’s chip to be used as part of a counterfeit travel document. This violates the authenticity of the travel document’s chip used for authentication of a traveller by possession of a travel document.

The attacker may generate a new data set or extract completely or partially the data from a genuine travel document’s chip and copy them to another appropriate chip to imitate this genuine travel document’s chip.

Threat agent: having high attack potential, being in possession of one or more legitimate travel documents

Asset: authenticity of user data stored on the TOE

This PP includes all threats from the PACE PP [7], chap 3.2, namely T.Skimming,

T.Eavesdropping, T.Tracing, T.Abuse-Func, T.Information_Leakage, T.Phys-Tamper,

T.Forgery and T.Malfunction. Due to identical definitions and names they are not repeated here as well.

Application note 8: T.Forgery from the PACE PP [7] shall be extended by the Extended

Inspection System additionally to the PACE authenticated BIS-PACE being outsmarted by the attacker.

Organisational Security Policies

The TOE shall comply with the following Organisational Security Policies (OSP) as security rules, procedures, practices, or guidelines imposed by an organisation upon its operations (see

CC part 1, sec. 3.2).

440

445

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 travel document holder. The sensitive biometric reference data can be used only by inspection systems which are authorized for this access at the time the travel document is presented to the inspection system (Extended Inspection Systems). The issuing

State or Organisation 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 travel document’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 Version 1.

450

455

P.Personalisation

Personalisation of the travel document by issuing State or Organisation only

The issuing State or Organisation guarantees the correctness of the biographical data, the printed portrait and the digitized portrait, the biometric reference data and other data of the logical travel document with respect to the travel document holder. The personalisation of the travel document for the holder is performed by an agent authorized by the issuing State or

Organisation only.

This PP includes all OSPs from the PACE PP [7], chap 3.3, namely P.Pre-Operational,

P.Card_PKI, P.Trustworthy_PKI, P.Manufact and P.Terminal. Due to identical definitions and names they are also not repeated here.

4 Security Objectives

This chapter describes the security objectives for the TOE and the security objectives for the

TOE environment. The security objectives for the TOE environment are separated into security objectives for the development and production environment and security objectives for the operational environment.

465

4.1

Security Objectives for the TOE

470

475

This section describes the security objectives for the TOE addressing the aspects of identified threats to be countered by the TOE and organisational security policies to be met by the TOE.

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 Organisation. The TOE must ensure the confidentiality of the logical travel document 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.

480

485

490

495

OT.Chip_Auth_Proof

Proof of the travel document’s chip authenticity

The TOE must support the Inspection Systems to verify the identity and authenticity of the travel document’s chip as issued by the identified issuing State or Organisation by means of the

Chip Authentication Version 1 as defined in [5]. The authenticity proof provided by travel document’s chip shall be protected against attacks with high attack potential.

Application note 9: The OT.Chip_Auth_Proof implies the travel document’s chip to have (i) a unique identity as given by the travel document’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 travel document’s chip i.e. a certificate for the Chip Authentication

Public Key that matches the Chip Authentication Private Key of the travel document’s chip.

This certificate is provided by (i) the Chip Authentication Public Key (EF.DG14) in the LDS defined in [6] and (ii) the hash value of DG14 in the Document Security Object signed by the

Document Signer.

This PP includes all Security Objectives for the TOE from the PACE PP [7], chap 4.1, namely

OT.Data_Integrity, OT.Data_Authenticity, OT.Data_Confidentiality, OT.Tracing,

OT.Prot_Abuse-Func, OT.Prof_Inf_Leak, OT.Prot_Phys-Tamper, OT.Identification,

OT.AC_Pers and OT.Prot_Malfunction. Due to identical definitions and names they are not repeated here as well.

Security Objectives for the Operational Environment

500

Issuing State or Organisation

The issuing State or Organisation will implement the following security objectives of the TOE environment.

505

510

OE.Auth_Key_Travel_Document Travel document Authentication Key

The issuing State or Organisation has to establish the necessary public key infrastructure in order to (i) generate the travel document’s Chip Authentication Key Pair, (ii) sign and store the

Chip Authentication Public Key in the Chip Authentication Public Key data in EF.DG14 and

(iii) support inspection systems of receiving States or Organisations to verify the authenticity of the travel document’s chip used for genuine travel document by certification of the Chip

Authentication Public Key by means of the Document Security Object.

Justification: This security objective for the operational environment is needed additionally to those from [7] in order to counter the Threat T.Counterfeit as it specifies the pre-requisite for the Chip Authentication Protocol Version 1 which is one of the additional features of the TOE described only in this Protection Profile and not in [7].

515

520

OE.Authoriz_Sens_Data

Authorization for Use of Sensitive Biometric Reference Data

The issuing State or Organisation has to establish the necessary public key infrastructure in order to limit the access to sensitive biometric reference data of travel document holders to authorized receiving States or Organisations. The Country Verifying Certification Authority of the issuing State or Organisation generates card verifiable Document Verifier Certificates for the authorized Document Verifier only.

Justification: This security objective for the operational environment is needed additionally to those from [7] in order to handle the Threat T.Read_Sensitive_Data, the Organisational

Security Policy P.Sensitive_Data and the Assumption A.Auth_PKI as it specifies the prerequisite for the Terminal Authentication Protocol v.1 as it concerns the need of an PKI for this protocol and the responsibilities of its root instance. The Terminal Authentication Protocol v.1 is one of the additional features of the TOE described only in this Protection Profile and not in

[7].

525

Receiving State or Organisation

The receiving State or Organisation will implement the following security objectives of the

TOE environment.

530

OE.Exam_Travel_Document

Examination of the physical part of the travel document

The inspection system of the receiving State or Organisation must examine the travel document presented by the traveller to verify its authenticity by means of the physical security measures and to detect any manipulation of the physical part of the travel document. The Basic

Inspection System for global interoperability (i) includes the Country Signing CA Public Key

Bundesamt für Sicherheit in der Informationstechnik 21

535

540

1.3.0, 20 th January 2012 Common Criteria Protection Profile

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE and the Document Signer Public Key of each issuing State or Organisation, and (ii) implements the terminal part of PACE [4] and/or the Basic Access Control [6]. Extended Inspection

Systems perform additionally to these points the Chip Authentication Protocol Version 1 to verify the Authenticity of the presented travel document’s chip.

Justification: This security objective for the operational environment is needed additionally to those from [7] in order to handle the Threat T.Counterfeit and the Assumption A.Insp_Sys by demanding the Inspection System to perform the Chip Authentication protocol v.1.

OE.Exam_Travel_Document also repeats partly the requirements from OE.Terminal in [7] and therefore also counters T.Forgery and A.Passive_Auth from [7]. This is done because a new type of Inspection System is introduced in this PP as the Extended Inspection System is needed to handle the additional features of a travel document with Extended Access Control.

545

550

OE.Prot_Logical_Travel_Document

Protection of data from the logical travel document

The inspection system of the receiving State or Organisation ensures the confidentiality and integrity of the data read from the logical travel document. The inspection system will prevent eavesdropping to their communication with the TOE before secure messaging is successfully established based on the Chip Authentication Protocol Version 1.

Justification: This security objective for the operational environment is needed additionally to those from [7] in order to handle the Assumption A.Insp_Sys by requiring the Inspection

System to perform secure messaging based on the Chip Authentication Protocol v.1.

555

560

565

OE.Ext_Insp_Systems

Authorization of Extended Inspection Systems

The Document Verifier of receiving States or Organisations authorizes Extended Inspection

Systems by creation of Inspection System Certificates for access to sensitive biometric reference data of the logical travel document. The Extended Inspection System authenticates themselves to the travel document’s chip for access to the sensitive biometric reference data with its private Terminal Authentication Key and its Inspection System Certificate.

Justification: This security objective for the operational environment is needed additionally to those from [7] in order to handle the Threat T.Read_Sensitive_Data, the Organisational

Security Policy P.Sensitive_Data and the Assumption A.Auth_PKI as it specifies the prerequisite for the Terminal Authentication Protocol v.1 as it concerns the responsibilities of the

Document Verifier instance and the Inspection Systems.

This PP includes all Security Objectives of the TOE environment from the PACE PP [7], chap.

4.2, namely OE.Legislative_Compliance, OE.Passive_Auth_Sign, OE.Personalisation,

OE.Terminal, and OE.Travel_Document_Holder. Due to identical definitions and names they are not repeated here.

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE

Table 1: Security Objective Rationale

The OSP P.Personalisation “Personalisation of the travel document by issuing State or

Organisation only” addresses the (i) the enrolment of the logical travel document by the

Personalisation Agent as described in the security objective for the TOE environment

OE.Personalisation “Personalisation of logical travel document”, and (ii) the access control for the user data and TSF data as described by the security objective OT.AC_Pers “Access

Control for Personalisation of logical travel document”. Note the manufacturer equips the TOE with the Personalisation 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 Personalisation 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 Organisation as required by

OE.Authoriz_Sens_Data “Authorization for use of sensitive biometric reference data”. The

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 OSP P.Terminal “Abilities and trustworthiness of terminals” is countered by the security objective OE.Exam_Travel_Document additionally to the security objectives from PACE PP

[7]. OE.Exam_Travel_Document enforces the terminals to perform the terminal part of the

PACE protocol.

The threat T.Counterfeit “Counterfeit of travel document chip data” addresses the attack of unauthorized copy or reproduction of the genuine travel document's chip. This attack is thwarted by chip an identification and authenticity proof required by OT.Chip_Auth_Proof

“Proof of travel document’s chip authentication” using an authentication key pair to be generated by the issuing State or Organisation. 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_Travel_Document “Travel document Authentication Key”. According to

OE.Exam_Travel_Document “Examination of the physical part of the travel document” the

General Inspection system has to perform the Chip Authentication Protocol Version 1 to verify the authenticity of the travel document’s chip.

The threat T.Forgery “Forgery of data” addresses the fraudulent, complete or partial alteration of the User Data or/and TSF-data stored on the TOE or/and exchanged between the TOE and the terminal. Additionally to the security objectives from PACE PP [7] which counter this threat, the examination of the presented MRTD passport book according to

OE.Exam_Travel_Document “Examination of the physical part of the travel document” shall ensure its authenticity by means of the physical security measures and detect any manipulation of the physical part of the travel document.

Common Criteria Protection Profile 1.3.0, 20 th January 2012

Machine Readable Travel Document with „ICAO Application", Extended Access Control with PACE

The examination of the travel document addressed by the assumption A.Insp_Sys “Inspection

Systems for global interoperability” is covered by the security objectives for the TOE environment OE.Exam_Travel_Document “Examination of the physical part of the travel document” which requires the inspection system to examine physically the travel document, the

Basic Inspection System to implement the Basic Access Control, and the Extended Inspection

Systems to implement and to perform the Chip Authentication Protocol Version 1 to verify the

Authenticity of the presented travel document’s chip. The security objectives for the TOE environment OE.Prot_Logical_Travel_Document “Protection of data from the logical travel document” require the Inspection System to protect the logical travel document data during the transmission and the internal handling.

The assumption A.Passive_Auth “PKI for Passive Authentication” is directly covered by the security objective for the TOE environment OE.Passive_Auth_Sign “Authentication of travel document by Signature” from PACE PP [7] 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_Travel_Document “Examination of the physical part of the travel document”.

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

Organisations 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 Organisation has to establish the necessary public key infrastructure.

5.1

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.

Application note 10: 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.

6 Security Requirements

The CC allows several operations to be performed on functional requirements; refinement,

selection, assignment, and iteration are defined in paragraph C.4 of Part 1 [1] of the CC. Each of these operations is used in this PP.

The refinement operation is used to add detail to a requirement, and thus further restricts a requirement. Refinement of security requirements is denoted by the word “refinement” in bold text and the added/changed words are in bold text. In cases where words from a CC requirement were deleted, a separate attachment indicates the words that were removed.

The selection operation is used to select one or more options provided by the CC in stating a requirement. Selections that have been made by the PP authors are denoted as underlined text and the original text of the component is given by a footnote. Selections to be filled in by the

ST author appear in square brackets with an indication that a selection is to be made,

[selection:], and are italicized.

The assignment operation is used to assign a specific value to an unspecified parameter, such as the length of a password. Assignments that have been made by the PP authors are denoted by showing as underlined text and the original text of the component is given by a footnote.

Assignments to be filled in by the ST author appear in square brackets with an indication that an assignment is to be made [assignment:], and are italicized. In some cases the assignment made by the PP authors defines a selection to be performed by the ST author. Thus this text is underlined and italicized like this.

The iteration operation is used when a component is repeated with varying operations.

Iteration is denoted by showing a slash “/”, and the iteration indicator after the component identifier.

The definition of the subjects “Manufacturer”, “Personalisation Agent”, “Extended Inspection

System”, “Country Verifying Certification Authority”, “Document Verifier” and “Terminal” used in the following chapter is given in section 3.1. Note, that all these subjects are acting for homonymous external entities. All used objects are defined either in section 7 or in the following table. The operations “write”, “modify”, “read” and “disable read access” are used in accordance with the general linguistic usage. The operations “store”, “create”, “transmit”,

“receive”, “establish communication channel”, “authenticate” and “re-authenticate” are originally taken from [2]. The operation “load” is synonymous to “import” used in [2].

FIA_UID.1.2/PACE The TSF shall require each user to be successfully identified before allowing any other TSF-mediated actions on behalf of that user.

Application note 20: The SFR FIA_UID.1/PACE in the current PP covers the definition in

PACE PP [7] and extends it by EAC aspect 4. This extension does not conflict with the strict conformance to PACE PP.

Application note 21: 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-personalisation

Data in the audit records of the IC. The travel document manufacturer may create the user role

Personalisation Agent for transition from Phase 2 to Phase 3 “Personalisation of the travel document”. The users in role Personalisation Agent identify themselves by means of selecting the authentication key. After personalisation in the Phase 3 the PACE domain parameters, the

Chip Authentication data and Terminal Authentication Reference Data are written into the

TOE. The Inspection System is identified as default user after power up or reset of the TOE i.e. the TOE will run the PACE protocol, to gain access to the Chip Authentication Reference Data and to run the Chip Authentication Protocol Version 1. 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 Version 1 or (ii) if necessary and available by authentication as Personalisation Agent (using the Personalisation Agent Key).

Application note 22: User identified after a successfully performed PACE protocol is a terminal. Please note that neither CAN nor MRZ effectively represent secrets, but are restricted revealable; i.e. it is either the travel document holder itself or an authorised other person or device (Basic Inspection System with PACE).

Application note 23: In the life-cycle phase ‘Manufacturing’ the Manufacturer is the only user role known to the TOE. The Manufacturer writes the Initialisation Data and/or Prepersonalisation Data in the audit records of the IC.

Please note that a Personalisation Agent acts on behalf of the travel document Issuer under his and CSCA and DS policies. Hence, they define authentication procedure(s) for Personalisation

Agents. The TOE must functionally support these authentication procedures being subject to evaluation within the assurance components ALC_DEL.1 and AGD_PRE.1. The TOE assumes the user role ‘Personalisation Agent’, when a terminal proves the respective Terminal

Authorisation Level as defined by the related policy (policies).

Application note 48: The ST writer shall perform the operation in FPT_EMS.1.1 and

FPT_EMS.1.2. The TOE shall prevent attacks against the listed secret data where the attack is based on external observable physical phenomena of the TOE. Such attacks may be observable at the interfaces of the TOE or may be originated from internal operation of the TOE or may be caused by an attacker that varies the physical environment under which the TOE operates. The set of measurable physical phenomena is influenced by the technology employed to implement the smart card. The travel document’s chip can provide a smart card contactless interface and contact based interface according to ISO/IEC 7816-2 [14] as well (in case the package only provides a contactless interface the attacker might gain access to the contacts anyway).

Examples of measurable phenomena include, but are not limited to variations in the power consumption, the timing of signals and the electromagnetic radiation due to internal operations or data transmissions.

The following security functional requirements address the protection against forced illicit information leakage including physical manipulation.

Manufacturer to write Initialisation and Pre-personalisation Data (including the Personalisation

Agent key). The SFR FMT_MTD.1/INI_DIS requires the Personalisation Agent to disable access to Initialisation and Pre-personalisation Data in the life cycle phase ‘operational use’.

The SFRs FMT_SMF.1 and FMT_SMR.1/PACE support the functions and roles related.

The security objective OT.AC_Pers “Access Control for Personalisation of logical travel document” addresses the access control of the writing the logical travel document. The justification for the SFRs FAU_SAS.1, FMT_MTD.1/INI_ENA and FMT_MTD.1/INI_DIS arises from the justification for OT.Identification above with respect to the Pre-personalisation

Data. The write access to the logical travel document data are defined by the SFR

FIA_UID.1/PACE, FIA_UAU.1/PACE, FDP_ACC.1/TRM and FDP_ACF.1/TRM in the same way: only the successfully authenticated Personalisation Agent is allowed to write the data of the groups EF.DG1 to EF.DG16 of the logical travel document only once. FMT_MTD.1/PA covers the related property of OT.AC_Pers (writing SO

D

and, in generally, personalisation data). The SFR FMT_SMR.1/PACE lists the roles (including Personalisation Agent) and the

SFR FMT_SMF.1 lists the TSF management functions (including Personalisation). The SFRs

FMT_MTD.1./KEY_READ and FPT_EMS.1 restrict the access to the Personalisation Agent

Keys and the Chip Authentication Private Key.

The authentication of the terminal as Personalisation Agent shall be performed by TSF according to SFR FIA_UAU.4/PACE and FIA_UAU.5/PACE. If the Personalisation Terminal want to authenticate itself to the TOE by means of the Terminal Authentication Protocol v.1

(after Chip Authentication v.1) with the Personalisation Agent Keys the TOE will use TSF according to the FCS_RND.1 (for the generation of the challenge), FCS_CKM.1/CA (for the derivation of the new session keys after Chip Authentication v.1), and FCS_COP.1/CA_ENC and FCS_COP.1/CA_MAC (for the ENC_MAC_Mode secure messaging),

FCS_COP.1/SIG_VER (as part of the Terminal Authentication Protocol v.1) and

FIA_UAU.6/EAC (for the re-authentication). If the Personalisation Terminal wants to authenticate itself to the TOE by means of the Authentication Mechanism with Personalisation

Agent Key the TOE will use TSF according to the FCS_RND.1 (for the generation of the challenge) and FCS_COP.1/CA_ENC (to verify the authentication attempt). The session keys are destroyed according to FCS_CKM.4 after use.

The security objective OT.Data_Integrity “Integrity of personal data” requires the TOE to protect the integrity of the logical travel document stored on the travel document’s chip against physical manipulation and unauthorized writing. Physical manipulation is addressed by

FPT_PHP.3. Logical manipulation of stored user data is addressed by (FDP_ACC.1/TRM,

FDP_ACF.1/TRM): only the Personalisation Agent is allowed to write the data in EF.DG1 to

EF.DG16 of the logical travel document (FDP_ACF.1.2/TRM, rule 1) and terminals are not allowed to modify any of the data in EF.DG1 to EF.DG16 of the logical travel document (cf.

FDP_ACF.1.4/TRM). FMT_MTD.1/PA requires that SO

D

containing signature over the User

Data stored on the TOE and used for the Passive Authentication is allowed to be written by the

Personalisation Agent only and, hence, is to be considered as trustworthy. The Personalisation

Agent must identify and authenticate themselves according to FIA_UID.1/PACE and

FIA_UAU.1/PACE before accessing these data. FIA_UAU.4/PACE, FIA_UAU.5/PACE and

FCS_CKM.4 represent some required specific properties of the protocols used. The SFR

FMT_SMR.1/PACE lists the roles and the SFR FMT_SMF.1 lists the TSF management functions.

Unauthorised modifying of the exchanged data is addressed, in the first line, by

FTP_ITC.1/PACE using FCS_COP.1/PACE_MAC. For PACE secured data exchange, a prerequisite for establishing this trusted channel is a successful PACE Authentication

(FIA_UID.1/PACE, FIA_UAU.1/PACE) using FCS_CKM.1/DH_PACE and possessing the special properties FIA_UAU.5/PACE, FIA_UAU.6/PACE resp. FIA_UAU.6/EAC. The trusted channel is established using PACE, Chip Authentication v.1, and Terminal Authentication v.1.

FDP_RIP.1 requires erasing the values of session keys (here: for K

).

The TOE supports the inspection system detect any modification of the transmitted logical travel document data after Chip Authentication v.1. The SFR FIA_UAU.6/EAC and

FDP_UIT.1/TRM requires the integrity protection of the transmitted data after Chip

Authentication v.1 by means of secure messaging implemented by the cryptographic functions according to FCS_CKM.1/CA (for the generation of shared secret andfor the derivation of the new session keys), and FCS_COP.1/CA_ENC and FCS_COP.1/CA_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 SFR FCS_RND.1 represents a general support for cryptographic operations needed.

The security objective OT.Data_Authenticity aims ensuring authenticity of the User- and TSF data (after the PACE Authentication) by enabling its verification at the terminal-side and by an active verification by the TOE itself.

This objective is mainly achieved by FTP_ITC.1/PACE using FCS_COP.1/PACE_MAC. A prerequisite for establishing this trusted channel is a successful PACE or Chip and Terminal

Authentication v.1 (FIA_UID.1/PACE, FIA_UAU.1/PACE) using FCS_CKM.1/DH_PACE resp. FCS_CKM.1/CA and possessing the special properties FIA_UAU.5/PACE,

FIA_UAU.6/PACE resp. FIA_UAU.6/EAC. FDP_RIP.1 requires erasing the values of session keys (here: for KMAC).

FIA_UAU.4/PACE, FIA_UAU.5/PACE and FCS_CKM.4 represent some required specific properties of the protocols used. The SFR FMT_MTD.1./KEY_READ restricts the access to the PACE passwords and the Chip Authentication Private Key.

FMT_MTD.1/PA requires that SO

D

containing signature over the User Data stored on the TOE and used for the Passive Authentication is allowed to be written by the Personalisation Agent only and, hence, is to be considered as trustworthy.

The SFR FCS_RND.1 represents a general support for cryptographic operations needed.

The SFRs FMT_SMF.1 and FMT_SMR.1/PACE support the functions and roles related.

The security objective OT.Data_Confidentiality aims that the TOE always ensures confidentiality of the User- and TSF-data stored and, after the PACE Authentication resp. Chip

Authentication, of these data exchanged.

This objective for the data stored is mainly achieved by (FDP_ACC.1/TRM,

FDP_ACF.1/TRM). FIA_UAU.4/PACE, FIA_UAU.5/PACE and FCS_CKM.4 represent some required specific properties of the protocols used.

This objective for the data exchanged is mainly achieved by FDP_UCT.1/TRM,

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/TRM and

FDP_ACF.1/TRM allowing the data of EF.DG3 and EF.DG4 only to be read by successfully authenticated Extended Inspection System being authorized by a valid certificate according

FCS_COP.1/SIG_VER.

The SFRs FIA_UID.1/PACE and FIA_UAU.1/PACE require the identification and authentication of the inspection systems. The SFR FIA_UAU.5/PACE requires the successful

Chip Authentication (CA) v.1 before any authentication attempt as Extended Inspection

System. During the protected communication following the CA v.1 the reuse of authentication data is prevented by FIA_UAU.4/PACE. The SFR FIA_UAU.6/EAC and FDP_UCT.1/TRM requires the confidentiality protection of the transmitted data after Chip Authentication v.1 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/CA

(for the generation of shared secret and for the derivation of the new session keys), and

FCS_COP.1/CA_ENC and FCS_COP.1/CA_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.Chip_Auth_Proof “Proof of travel document’s chip authenticity” is ensured by the Chip Authentication Protocol v.1 provided by FIA_API.1 proving the identity of the TOE. The Chip Authentication Protocol v.1 defined by FCS_CKM.1/CA 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 v.1 [5] requires additional TSF according to FCS_CKM.1/CA (for the derivation of the session keys), FCS_COP.1/CA_ENC and FCS_COP.1/CA_MAC (for the ENC_MAC_Mode secure messaging).

The SFRs FMT_SMF.1 and FMT_SMR.1/PACE support the functions and roles related.

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 travel document’s chip

6.3.3 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 travel document’s development and manufacturing especially for the secure handling of the travel document’s material.

The selection of the component ATE_DPT.2 provides a higher assurance than the pre-defined

EAL4 package due to requiring the functional testing of SFR-enforcing modules.

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 fulfil the security objectives OT.Sens_Data_Conf and OT.Chip_Auth_Proof.

The component ALC_DVS.2 has no dependencies.

The component ATE_DPT.2 has the following dependencies:

6.3.4 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 analysed, and non-satisfied dependencies are appropriately explained.

All subjects and objects addressed by more than one SFR in sec. 6.1 are also treated in a consistent way: the SFRs impacting them do not require any contradictory property and behaviour of these ‘shared’ items.

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.

This role is usually delegated to a Personalisation Agent.

An organisation enforcing the policies of the CVCA and of a Service

Provider (here: of a governmental organisation / inspection authority) and managing terminals belonging together (e.g. terminals operated by a

State’s border police), by – inter alia – issuing Terminal Certificates. A

Document Verifier is therefore a Certification Authority, authorised by at least the national CVCA to issue certificates for national terminals, see [5].

Since the Standard Inspection Procedure does not imply any certificatebased terminal authentication, the current TOE cannot recognise a DV as a subject; hence, it merely represents an organisational entity within this PP.

There can be Domestic and Foreign DV: A domestic DV is acting under the policy of the domestic CVCA being run by the travel document

Issuer; a foreign DV is acting under a policy of the respective foreign

CVCA (in this case there shall be an appropriate agreement between the travel document Issuer und a foreign CVCA ensuring enforcing the

travel document Issuer’s privacy policy).

55 The form of such an agreement may be of formal and informal nature; the term ‘agreement’ is used in the current PP in order to reflect an appropriate relationship between the parties involved.

56 Existing of such an agreement may be technically reflected by means of issuing a CCVCA-F for the Public Key of the foreign CVCA signed by the domestic CVCA.

Definition

Organisation personalised the travel document.

A contact based/contactless integrated circuit chip complying with

ISO/IEC 14443 [15] and programmed according to the Logical Data

Structure as specified by ICAO, [6], sec III.

Software embedded in a travel document’s chip and not being developed by the IC Designer. The travel document’s chip Embedded

Software is designed in Phase 1 and embedded into the travel document’s chip in Phase 2 of the TOE life-cycle.

Person presenting the travel document to the inspection system and claiming the identity of the travel document holder.

Data created by and for the TOE that might affect the operation of the

TOE (CC part 1 [1]).

The travel document that contains the travel document chip holding only Initialization Data and Pre-personalisation Data as delivered to the

Personalisation Agent from the Manufacturer.

All data (being not authentication data)

(i) stored in the context of the ePassport application of the travel document as defined in [5] and

(ii) being allowed to be read out solely by an authenticated terminal acting as Basic Inspection System with PACE .

CC give the following generic definitions for user data:

Data created by and for the user that does not affect the operation of the

TSF (CC part 1 [1]). Information stored in TOE resources that can be operated upon by users in accordance with the SFRs and upon which the

TSF places no special meaning (CC part 2 [2]).

The process of comparing a submitted biometric sample against the biometric reference template of a single enrollee whose identity is being claimed, to determine whether it matches the enrollee’s template. [6]

Data provided by an entity in an authentication attempt to prove their identity to the verifier. The verifier checks whether the verification data match the reference data known for the claimed identity.
