Certification Report
Executive Summary
Target of Evaluation (TOE) and subject of the Security Target (ST) [6] and [7] is
the smartcard product “Tachograph Card Version 1.0 128/64 R1.0”.
The TOE will be used within the Tachograph System as a security medium
which carries a specific Tachograph Application intended for its use with the
recording equipment.
The basic functions of the Tachograph Card are:
·
·
to store card identification and card holder identification data. These data
are used by the vehicle unit to identify the cardholder, provide
accordingly functions and data access rights, and ensure cardholder
accountability for his activities,
to store cardholder activities data, events and faults data and control
activities data, related to the cardholder.
A Tachograph Card is therefore intended to be used by a card interface device
of a vehicle unit. It may also be used by any card reader (e.g. of a personal
computer) which shall have full read access right on any user data. During the
end-usage phase of a Tachograph Card life cycle (phase 7 of life-cycle as
described), vehicle units only may write user data to the card. A Tachograph
Card is either of the type Driver Card or Control Card or Workshop Card or
Company Card as outlined in the ST [7], chapter 2.4.
The TOE comprises the following components:
·
Integrated Circuit (IC) "Philips P16WX064V0C Secure 16-bit Smart Card
Controller " provided by Philips Semiconductors GmbH
·
Caernarvon Cryptographic Library on Philips Smart XA2 as IC Dedicated
Support Software provided by Philips Semiconductors GmbH
·
Smartcard Embedded Software based on a Java Card Platform Version
2.1.1 with a specific Java Card Applet for the Tachograph Application
provided by ORGA Kartensysteme GmbH.
The Java Card Applet for the Tachograph Application consists of a fix part containing the executable code and another configurable part for the Tachograph
Card´s filesystem which depends on the respective card type. In this sense, the
TOE will be produced and delivered in four different configurations.
The TOE is developed and constructed in full accordance with the Tachograph
Card Specification [8], Annex 1B main body, Appendix 2, Appendix 10 (Tachograph Card Generic Security Target) and Appendix 11. In particular, this implies
the conformance of the Tachograph Card with the following standards: ISO/IEC
7810 Identification cards – Physical characteristics, ISO/IEC 7816 Identification
cards - Integrated circuits with contacts: part 1, part 2, part 3, part 4 and part 8;
ISO/IEC 10373 Identification cards – Test methods.

Certification Report
BSI-DSZ-CC-0205-2003
In order to achieve the required system security, the Tachograph Card and the
corresponding ST [6] and [7] meet all the security requirements and evaluation
conditions defined in the Tachograph Card´s “Generic Security Target” in [8],
Appendix 10 under consideration of the interpretations in [9].
The life-cycle of the TOE conforms to the smartcard life cycle described in
Appendix 10 of [8] referring to PP/9911 [13]. The following table outlines this
life-cycle for the TOE:
Phase
Description
Phase 1 Smartcard Embedded The Smartcard Embedded Software Developer (ORGA
Software Development Kartensysteme GmbH, Paderborn) is in charge of the
Smartcard Embedded Software (Basic Software, Application Software) development and the specification of IC
initialisation and pre-personalisation requirements.
Phase 2 IC Development
The IC Designer (Philips Semiconductors GmbH) designs
the IC, develops IC Dedicated Software, provides information, software or tools to the Smartcard Embedded Software Developer, and receives the Smartcard Embedded
Software (only Basic Software) from the developer through
trusted delivery and verification procedures.
The IC Designer constructs the smartcard IC database,
necessary for the IC photomask fabrication.
Phase 3 IC Manufacturing and The IC Manufacturer (Philips Semiconductors GmbH)
Testing
generates the masks for the IC manufacturing based upon
an output from the smartcard IC database.
He is responsible for producing the IC through three main
steps: IC manufacturing, IC testing, and IC prepersonalisation.
Phase 4 IC Packaging and
Testing
The IC Packaging Manufacturer (ORGA Kartensysteme
GmbH, Flintbek) is responsible for the IC packaging (production of modules) and testing.
Phase 5 Smartcard
Product The Smartcard Product Manufacturer (ORGA KartensysFinishing Process
teme GmbH, Flintbek) is responsible for the initialisation of
the TOE (in form of initialisation of the modules of phase 4)
and its testing. In this phase the TOE becomes either the
type Driver Card or Control Card or Workshop Card or
Company Card.
The smartcard product finishing process comprises the
embedding of the initialised modules for the TOE and the
card production what is done alternatively by ORGA
Kartensysteme GmbH or by the customer.

Phase 7 Smartcard
End-usage
(i)
The TOE is delivered to the customer in form of a
complete (initialised) smartcard.
(ii)
Alternatively, the TOE is delivered to the customer
in form of an initialised module. In this case, the
smartcard finishing process (embedding, final
tests) is task of the customer.
The Personaliser is responsible

The Smartcard Issuer is responsible for the smartcard
product delivery to the smartcard end-user, and the end of
life process.
Table 1: Life cycle of the TOE
The evaluation of the TOE was conducted as a composition evaluation making
use of the platform evaluation results of the CC evaluations
·
of the underlying semiconductor "Philips P16WX064V0C Secure 16-bit
Smart Card Controller“ provided by Philips Semiconductors GmbH [18]
and
·
of the underlying semiconductor "Philips P16WX064V0C Secure 16-bit
Smart Card Controller with Caernarvon Cryptographic Library on Philips
Smart XA2 as IC Dedicated Support Software" provided by Philips Semiconductors GmbH.
Both, the IC itself and the IC with its IC Dedicated Software were evaluated
according to Common Criteria EAL 5 augmented with a minimum strength level
for its security functions of SOF-high based on the Protection Profile BSI-PP0002 [12]. These platform evaluations were performed by T-Systems GEI
GmbH.
The Embedded Software of the “Tachograph Card Version 1.0 128/64 R1.0”
and the overall composition was evaluated by SRC Security Research &
Consulting GmbH.
The concept for composition as outlined in CC Supporting Document [4, AIS 36]
was used.
The evaluation was completed on 01 August 2003. Both, the SRC Security
Research & Consulting GmbH and the evaluation facility of T-Systems GEI
GmbH are evaluation facilities (ITSEF)8 recognised by BSI. The sponsor,
vendor and distributor of the Tachograph Card Version 1.0 128/64 R1.0 is

Special configuration requirements
The TOE is delivered at the end of phase 5 in form of complete cards, i.e. after
the initialisation process of the TOE has been successfully finished, final tests
have been successfully conducted and the card production has been fulfilled.
Alternatively, the TOE is delivered in form of initialised and tested modules. In
this case, the smartcard finishing process (embedding of the delivered modules,
final tests) is task of the customer.
During initialisation a TOE as a Tachograph Card becomes one of the following
types: Driver Card, Control Card, Workshop Card or Company Card as defined
in [8] depending on the specific applet and data loaded into the card. The
Tachograph Card allows a personalisation only after a successful preceding
mutual authentication between the Tachograph Card and the external world and
only with secured data transfer. The keys necessary for the authentication procedure during the personalisation process are part of the Application Software
resp. the Tachograph Applets and are loaded onto the card in the framework of
the initialisation. At the end of the personalisation process, the card is switched
to the end-user operational phase.
There are no special security measures for the start-up of the TOE besides the
requirement that the TOE has to be used under the well-defined operating conditions and that the requirements on the personalisation and usage have to be
applied as described in the user documentation [15], [16] and [17].
1.6
Assumptions about the operating environment
The TOE is intended to be used within the Tachograph System as a security
medium which carries a specific Tachograph Application intended for its use
with the recording equipment as specified in [8].
There do not exist any Tachograph Card specific assumptions for the environment of the TOE. The following general assumptions are made based on the
PP/9911 [13] and PP/9806 [14] referenced in Appendix 10 of Annex 1B of
Regulation (EC) no. 1360/2002 [8] (Generic Security Target).

Additionally, an assumption (A.PERS) on secure generation and handling of
personalisation data is made because the establishment of a secure environment for the personalisation process with adequate personnel, organisational
and technical security measures is in the responsibility of the personalisation
centre itself. The security of the personalisation process of the TOE is
supported by the TOE itself.

To ensure that the customer receives this evaluated version, the delivery procedures described in the User documentation for personalisation [15] have to
be followed. The Tachograph Card Version 1.0 128/64 R1.0 Data Sheet
includes File Control Information (FCI) which can be used for identification of
the four different card types.

Security Policy
The TOE will be employed within the Tachograph System as a security medium
which carries a specific Tachograph Application intended for its use with the
recording equipment.
The TOE is the composition of the IC, IC Dedicated Software and Smartcard
Embedded Software. The security policy is to provide:
·
protection against leakage of information (e.g. to ensure the confidentiality of cryptographic keys during cryptographic functions performed by the
TOE), against physical probing, against malfunctions, against physical
manipulations, against access for code and data memory and against
abuse of functionality
·
secure storage of user data and TSF data
·
access control to user data and TSF data according to the specified rules
·
secure communication to the vehicle unit of the Tachograph System
as specified in Appendix 10 of Annex 1B of Regulation (EC) no. 1360/2002 [8].
4
Assumptions and Clarification of Scope
The TOE is intended to be used within the Tachograph System as a security
medium which carries a specific Tachograph Application intended for its use
with the recording equipment as specified in [8].
There do not exist any Tachograph Card specific assumptions for the environment of the TOE as the definition of the card type is done during the TOE initialisation in phase 5 before delivery.
General assumptions are made based on the PP/9911 [13] and PP/9806 [14]
referenced in Appendix 10 of Annex 1B of Regulation (EC) no. 1360/2002 [8]
(Generic Security Target). These general assumptions are structured according
to the phases of the life cycle. Some of these assumptions are related to procedures in phases 1 to 5. These phases were part of the TOE evaluation. As
delivery of the TOE is defined within or at the end of phase 5 of the life cycle.
(see table 1), the phases 6 and 7 are the usage phases of the TOE. Procedures
related to assumptions on these phases and the additional assumption A.PERS
on secure generation and handling of personalisation data are outlined in the
user documentation.

The TOE is the Tachograph Card Version 1.0 128/64 R1.0 providing security
functions as required in Appendix 10 of Annex 1B of Regulation (EC) no.
1360/2002 [8] (Generic Security Target). Threats on the overall Tachograph
System which are not related to the Tachograph Smartcards were not
addressed by this product evaluation.

Architectural Information
The TOE is a product. It is composed from an Integrated Circuit (IC) with its
proprietary IC Dedicated Software and a Smartcard Embedded Software (ES),
consisting of Basic Software (BS) and Application Software (AS). The Design of
the Embedded Software is based on the Java Card Platform Version 2.1.1 with
a dedicated Java Card Applet for the Tachograph Card application. The four
different card types are distinguished as they contain a specific applet each,
and specific data structures and data.
As all parts of TOE software are running inside the IC, the external interface of
the TOE to its environment can be defined as the external interface of this IC,
the Philips P16WX064V0C Secure 16-bit Smart Card Controller. The external
interface is divided into a physical / electrical interface and a logical interface.
The physical / electrical interface of the P16WX064V0C are the pads to connect
the lines supply voltage, reset input, clock input, ground and I/O. An external
voltage and timing supply as well as a data interface are necessary for the
operation of the IC. Beyond the physical behaviour, the data interface is defined
by the Smart Card Embedded Software (ES). A user would use the physical
interface via the Chip card contacts. The electrical and physical characteristics
fulfilled are given in the Tachograph Cards Specification [8]. The location and
dimensions of the Chip card contacts comply with the ISO/IEC 7816-2. The
electronic signals, the working of the card as well as the power consumption are
in accordance with ISO/IEC 7816.
The logical interface consists of two parts: (i) everything below the command
level and (ii) the accessing of the Tachograph Cards by commands via the
command interface. Commands and protocols of the Tachograph Application
for phase 7 are fully described in the Tachograph Cards Specification [8].
Specific commands for the personalisation phase (phase 6) are described in the
User Guidance for the Personaliser [15].
The subsystems of the TOE are described in the ST [7], chapter 2.1. The TOE
Summary Specification (chapter 6 of the ST [7]) describes the TOE Securuity
Functions with relation to the IC and Cryptographic Library and to the
Embedded Software.

Documentation
The user of the TOE is
(i)
the developer of a vehicle unit who needs information how the TOE
interacts with the vehicle unit
(ii)
the personaliser of the Tachograph Cards who needs information about
security procedures and how the TOE supports the personalisation
process
(iii)
the issuer of the Tachograph Cards who needs information how to use
the 4 different card types after personalisation, information on specific
aspects of the issuance of the Tachograph Cards and information to be
passed to the end-user of the Tachograph Cards (card-holder, e.g. the
driver).
For these three types of users separate user documentation is provided (see
[15], [16] and [17]). Additionally, the Tachograph Card Version 1.0 128/64 R1.0,
Data Sheet [20] is provided by ORGA. It contains Answer To Reset (ATR)
information and File Control Information (FCI) as identification information for
the Tachograph Cards. As some data contained in the Data Sheet can be
customer specific, it will be provided individually for specific customers.
7
IT Product Testing
Tests of the TOE were done (i) with real cards using a card reader and a PC
and (ii) in an emulator test environment.
For those tests, where real cards are used, the specified method was used to
identify the Tachograph Card version and the correct card configuration for
every test. The real cards used for testing were either in initialised state (i. e.
ready for personalisation) or in operational state (i. e. personalisation completed). Using specific commands for reading FCI-data, the life cycle state of
the applet and the type of the card could be determined.
For identification of the correct versions of the electronic data used for tests in
the emulator test environment, and to determine whether the initial condition of
each test is satisfied, the methods of the evaluated Configuration Management
System were used. The version control mechanism can guarantee that the
design files and the initial data used for testing are those provided by the
developers for the specific version of the TOE under evaluation.
As specific subsystems are the same in all card types and others are different,
some tests had to be performed on all four card types, others could be re-used.
Tests after modifications of the TOE during the evaluation process were redone as necessary depending on the specific change.
B-18
BSI-DSZ-CC-0205-2003
Certification Report
Developer tests:
For developer tests, the test cases were mapped to Security Functions. All
Security Functions with their security properties and their interfaces were
covered. In addition, the test cases were mapped to subsystems of the HighLevel Design and to modules of the Low-Level Design. All subsystems and
modules with their security properties and their interfaces were covered. The
developer tested each property of the design specification. E.g. all command
APDU with valid and invalid inputs are tested and all functions are tested with
valid and invalid inputs. All test results were documented in log-files. All security
functions were tested with overall positive results.
Independent evaluator tests:
Most tests of the evaluator were done by ISO-7816 APDU command sequences
using a real card. Tests with emulators were chosen by the evaluators only for
those security functions, where internal resources of the card needed to be
modified or observed during the test (e.g. Anti-DPA-Measures and Residual
Information protection).
Several issues have been checked extensively by functional tests and by
source code analysis (e.g. I/O-testing, making sure that the protocol levels of
the TOE interface below ISO command level have stable behaviour; functional
Tachograph command testing including all possible error cases showing that no
undesired behaviour exits on command level which might be exploitable by an
attacker).
Side channel attacks on DES and RSA were tested and analysed. As the result
of these analysis, secret keys could not be extracted.
In addition, tests according to Appendix 9 of the EU Tachograph Card Commission Regulation [8] have been performed. Preliminary, the personalisation
process of the cards has been carried out and thereby tested. The tests have
been performed for all four different types of ORGA Tachograph Cards. For the
Appendix 9 tests, cards with the final ROM mask and the actual Tachograph
Applet have been used. The achieved test results correspond to the expected
test results (see Annex A of this report).
8
Evaluated Configuration
The TOE is delivered within or at the end of phase 5 in form of initialised and
tested complete cards or in form of initialised and tested modules (see table 1).
During the initialisation process at ORGA the TOE as a Tachograph Card
becomes one of the following types: Driver Card, Control Card, Workshop Card
or Company Card depending on the specific applet and data loaded into the
card. These four different card types are considered as different configurations
of the TOE.
All procedures for personalisation and configuration for the end-user necessary
after delivery are described in the user documentation [15].

Results of the Evaluation
The Evaluation Technical Report (ETR) [11] was provided by the ITSEF SRC
Security Research & Consulting GmbH according to the Common Criteria [1],
the Methodology [2], the requirements of the Scheme [3] and all interpretations
and guidelines of the Scheme (AIS) [4] as relevant for the TOE.
As the evaluation of the TOE was conducted as a composition evaluation, the
ETR [11] includes also the evaluation results of the composite evaluation activities in accordance with CC Supporting Document, ETR-lite for Compo
sition: Annex A Composite smartcard evaluation [4, AIS 36].
The ETR [11] builds up on the ETR-lite for Composition documents of the
evaluations of the underlying „Philips P16WX064V0C Secure 16-bit Smart Card
Controller“ and of the underlying „Philips P16WX064V0C Secure 16-bit Smart
Card Controller with Caernarvon Cryptographic Library on Philips Smart XA2 as
IC Dedicated Support Software". These ETR-lite for Composition documents
were provided by the ITSEF T-Systems GEI GmbH according to CC Supporting
Document, ETR-lite for Composition ([4, AIS 36]).
The evaluation methodology CEM [2] was used for those components identical
with EAL4. For components beyond EAL4 the methodology was defined in coordination with the Certification Body. For smartcard specific methodology the
scheme interpretations AIS 25, AIS 26 and AIS 36 (see [4]) were used. For
specific methodology on random number generator evaluation the scheme
interpretations AIS 20 and AIS 31 (see [4]) were used.
The assurance refinements outlined in the Security Target were followed in the
course of the evaluation of the TOE.

AIS 26 and AIS 31 (see [4]) were used. The rating of the strength of
functions does not include the cryptoalgorithms suitable for encryption
and decryption (see BSIG Section 4, Para. 3, Clause 2).
·
specific tests required by Appendix 9 of the EU Tachograph Card
Commission Regulation [8] are fulfilled (see Annex A of this report).
The results of the evaluation are only applicable to the Tachograph Card
Version 1.0 128/64 R1.0. The validity can be extended to new versions and
releases of the product, provided the sponsor applies for re-certification of the
modified product, in accordance with the procedural requirements, and the
evaluation of the modified product does not reveal any security deficiencies.
10
Comments/Recommendations
The User Guidance documentation (refer to chapter 6) contains necessary
information about the secure usage of the TOE. Additionally, for secure usage
of the TOE the fulfilment of the assumptions about the environment in the
Security Target [7] and the Security Target as a whole has to be taken into
account. Therefore a user/administrator has to follow the guidance in these
documents.

Excerpts from the Criteria
CC Part 1:
Caveats on evaluation results (chapter 5.4) / Final Interpretation 008
The conformance result indicates the source of the collection of requirements that is
met by a TOE or PP that passes its evaluation. This conformance result is presented
with respect to Part 2 (functional requirements), Part 3 (assurance requirements) and, if
applicable, to a pre-defined set of requirements (e.g., EAL, Protection Profile).
The conformance result consists of one of the following:
Part 2 conformant - A PP or TOE is Part 2 conformant if the functional requirements
are based only upon functional components in Part 2
Part 2 extended - A PP or TOE is Part 2 extended if the functional requirements
include functional components not in Part 2
plus one of the following:
Part 3 conformant - A PP or TOE is Part 3 conformant if the assurance requirements
are based only upon assurance components in Part 3
Part 3 extended - A PP or TOE is Part 3 extended if the assurance requirements
include assurance requirements not in Part 3.
Additionally, the conformance result may include a statement made with respect to sets
of defined requirements, in which case it consists of one of the following:
Package name Conformant - A PP or TOE is conformant to a pre-defined named
functional and/or assurance package (e.g. EAL) if the requirements (functions or
assurance) include all components in the packages listed as part of the conformance
result.
Package name Augmented - A PP or TOE is an augmentation of a pre-defined
named functional and/or assurance package (e.g. EAL) if the requirements (functions
or assurance) are a proper superset of all components in the packages listed as part of
the conformance result.
Finally, the conformance result may also include a statement made with respect to
Protection Profiles, in which case it includes the following:
PP Conformant - A TOE meets specific PP(s), which are listed as part of the
conformance result.

Evaluation assurance levels (chapter 6)
„The Evaluation Assurance Levels (EALs) provide an increasing scale that balances
the level of assurance obtained with the cost and feasibility of acquiring that degree of
assurance. The CC approach identifies the separate concepts of assurance in a TOE
at the end of the evaluation, and of maintenance of that assurance during the
operational use of the TOE.
It is important to note that not all families and components from Part 3 are included in
the EALs. This is not to say that these do not provide meaningful and desirable
assurances. Instead, it is expected that these families and components will be
considered for augmentation of an EAL in those PPs and STs for which they provide
utility.
Evaluation assurance level (EAL) overview (chapter 6.1)
Table 6.1 represents a summary of the EALs. The columns represent a hierarchically
ordered set of EALs, while the rows represent assurance families. Each number in the
resulting matrix identifies a specific assurance component where applicable.
As outlined in the next section, seven hierarchically ordered evaluation assurance
levels are defined in the CC for the rating of a TOE's assurance. They are hierarchically
ordered inasmuch as each EAL represents more assurance than all lower EALs. The
increase in assurance from EAL to EAL is accomplished by substitution of a
hierarchically higher assurance component from the same assurance family (i.e.
increasing rigour, scope, and/or depth) and from the addition of assurance components
from other assurance families (i.e. adding new requirements).
These EALs consist of an appropriate combination of assurance components as
described in chapter 2 of this Part 3. More precisely, each EAL includes no more than
one component of each assurance family and all assurance dependencies of every
component are addressed.
While the EALs are defined in the CC, it is possible to represent other combinations of
assurance. Specifically, the notion of “augmentation“ allows the addition of assurance
components (from assurance families not already included in the EAL) or the
substitution of assurance components (with another hierarchically higher assurance
component in the same assurance family) to an EAL. Of the assurance constructs
defined in the CC, only EALs may be augmented. The notion of an “EAL minus a
constituent assurance component“ is not recognised by the CC as a valid claim.
Augmentation carries with it the obligation on the part of the claimant to justify the utility
and added value of the added assurance component to the EAL. An EAL may also be
extended with explicitly stated assurance requirements.

BSI-DSZ-CC-0205-2003
Certification Report
Evaluation assurance level 1 (EAL1) - functionally tested (chapter 6.2.1)
„Objectives
EAL1 is applicable where some confidence in correct operation is required, but the
threats to security are not viewed as serious. It will be of value where independent
assurance is required to support the contention that due care has been exercised with
respect to the protection of personal or similar information.
EAL1 provides an evaluation of the TOE as made available to the customer, including
independent testing against a specification, and an examination of the guidance
documentation provided. It is intended that an EAL1 evaluation could be successfully
conducted without assistance from the developer of the TOE, and for minimal outlay.
An evaluation at this level should provide evidence that the TOE functions in a manner
consistent with its documentation, and that it provides useful protection against
identified threats.“
Evaluation assurance level 2 (EAL2) - structurally tested (chapter 6.2.2)
„Objectives
EAL2 requires the co-operation of the developer in terms of the delivery of design
information and test results, but should not demand more effort on the part of the
developer than is consistent with good commercial practice. As such it should not
require a substantially increased investment of cost or time.
EAL2 is therefore applicable in those circumstances where developers or users require
a low to moderate level of independently assured security in the absence of ready
availability of the complete development record. Such a situation may arise when
securing legacy systems, or where access to the developer may be limited.“
Evaluation assurance level 3 (EAL3) - methodically tested and checked
(chapter 6.2.3)
„Objectives
EAL3 permits a conscientious developer to gain maximum assurance from positive
security engineering at the design stage without substantial alteration of existing sound
development practices.
EAL3 is applicable in those circumstances where developers or users require a
moderate level of independently assured security, and require a thorough investigation
of the TOE and its development without substantial re-engineering.“
Evaluation assurance level 4 (EAL4) - methodically designed, tested, and
reviewed (chapter 6.2.4)
„Objectives
EAL4 permits a developer to gain maximum assurance from positive security
engineering based on good commercial development practices which, though rigorous,
C-5
Certification Report
BSI-DSZ-CC-0205-2003
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 therefore 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 additional security-specific engineering costs.“
Evaluation assurance level 5 (EAL5) - semiformally designed and tested
(chapter 6.2.5)
„Objectives
EAL5 permits a developer to gain maximum assurance from security engineering
based upon rigorous commercial development practices supported by moderate
application of specialist security engineering techniques. Such a TOE will probably be
designed and developed with the intent of achieving EAL5 assurance. It is likely that
the additional costs attributable to the EAL5 requirements, relative to rigorous
development without the application of specialised techniques, will not be large.
EAL5 is therefore applicable in those circumstances where developers or users require
a high level of independently assured security in a planned development and require a
rigorous development approach without incurring unreasonable costs attributable to
specialist security engineering techniques.“
Evaluation assurance level 6 (EAL6) - semiformally verified design and
tested (chapter 6.2.6)
„Objectives
EAL6 permits developers to gain high assurance from application of security
engineering techniques to a rigorous development environment in order to produce a
premium TOE for protecting high value assets against significant risks.
EAL6 is therefore applicable to the development of security TOEs for application in
high risk situations where the value of the protected assets justifies the additional
costs.“
Evaluation assurance level 7 (EAL7) - formally verified design and tested
(chapter 6.2.7)
„Objectives
EAL7 is applicable to the development of security TOEs for application in extremely
high risk situations and/or where the high value of the assets justifies the higher costs.
Practical application of EAL7 is currently limited to TOEs with tightly focused security
functionality that is amenable to extensive formal analysis.“

Strength of TOE security functions (AVA_SOF) (chapter 14.3)
AVA_SOF
Strength of TOE security functions
„Objectives
Even if a TOE security function cannot be bypassed, deactivated, or corrupted, it may
still be possible to defeat it because there is a vulnerability in the concept of its
underlying security mechanisms. For those functions a qualification of their security
behaviour can be made using the results of a quantitative or statistical analysis of the
security behaviour of these mechanisms and the effort required to overcome them. The
qualification is made in the form of a strength of TOE security function claim.“
Vulnerability analysis (AVA_VLA) (chapter 14.4)
AVA_VLA
Vulnerability analysis
„Objectives
Vulnerability analysis is an assessment to determine whether vulnerabilities identified,
during the evaluation of the construction and anticipated operation of the TOE or by
other methods (e.g. by flaw hypotheses), could allow users to violate the TSP.
Vulnerability analysis deals with the threats that a user will be able to discover flaws
that will allow unauthorised access to resources (e.g. data), allow the ability to interfere
with or alter the TSF, or interfere with the authorised capabilities of other users.“
„Application notes
A vulnerability analysis is performed by the developer in order to ascertain the
presence of security vulnerabilities, and should consider at least the contents of all the
TOE deliverables including the ST for the targeted evaluation assurance level. The
developer is required to document the disposition of identified vulnerabilities to allow
the evaluator to make use of that information if it is found useful as a support for the
evaluator's independent vulnerability analysis.“
„Independent vulnerability analysis goes beyond the vulnerabilities identified by the
developer. The main intent of the evaluator analysis is to determine that the TOE is
resistant to penetration attacks performed by an attacker possessing a low (for
AVA_VLA.2), moderate (for AVA_VLA.3) or high (for AVA_VLA.4) attack potential.“
