1 Executive Summary
The Target of evaluation (TOE) and subject of the Security Target (ST) [6] is the TCOS
Passport Version 2.0 Release 2-BAC/P5CD080V0B, a contactless integrated circuit chip
of machine readable travel documents (MRTD’s chip) programmed according to the
Logical Data Structure (LDS) [9] and providing the Basic Access Control according to
ICAO document [10]. It will be embedded as an inlay chip module into a passport booklet.
The smartcard operational system consists of the components Kernel, Admin Component,
Crypt Component, IO Component, (ROM) TCOS-Type Task and User-Type Task.
The certification of TCOS Passport Version 2.0 Release 2-BAC/P5CD080V0B is a re-
certification based on BSI-DSZ-CC-0445-2007 with the upgrade of the underlying
hardware to the IC used in TCOS Passport Version 2.0 Release 1 / P5CD080V0B
(Extended Access Control MRTD, certified under BSI-DSZ-CC-0446-2007) and the
integration of three different file systems.
The Security Target [6] is the basis for this certification. It is based on the certified
Protection Profile Machine Readable Travel Document with „ICAO Application", Basic
Access Control, version 1.0 (BSI-PP-0017-2005) [8].
The TOE security assurance requirements are based entirely on the assurance
components defined in part 3 of the Common Criteria (see part C or [1], part 3 for details).
The TOE meets the assurance requirements of the Evaluation Assurance Level EAL 4
augmented by ADV_IMP.2 and ALC_DVS.2.
The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the
Security Target [6], chapter 5.1. They are selected from Common Criteria Part 2 and some
of them are newly defined. Thus the TOE is CC part 2 extended.
The Security Functional Requirements (SFR) relevant for the IT-Environment of the TOE
are outlined in the Security Target [6], chapter 5.3.
The TOE Security Functional Requirements are implemented by the following TOE
Security Functions:

Table 2: Deliverables of the TOE
The TOE is finalized at the end of phase 2 according to the MRTD BAC PP [8]. Delivery is
performed from the Initialization facility to the personalisation facility by a secured transport
to a specific person of contact at the personalization site. Furthermore, the personalizer
receives information about the personalisation commands and process requirements. To
ensure that the personalizer receives this evaluated version, the procedures to start the
personalisation process as described in the Administrator´s Guide [15] have to be
followed.

BSI-DSZ-CC-0506-2008 Certification Report
3 Security Policy
The security policy of the TOE is defined according to the MRTD BAC PP [8] by the
security objectives and requirements for the contactless chip of machine readable travel
documents (MRTD) based on the requirements and recommendations of the International
Civil Aviation Organisation (ICAO). It addresses the advanced security methods Basic
Access Control in the Technical reports of the ICAO New Technology Working Group.
4 Assumptions and Clarification of Scope
The assumptions on Personalization of the MRTD’s chip and on Inspection Systems for
global interoperability as outlined above are of relevance.
The state or organisation issues the MRTD to be used by the holder for international
travel. The traveller presents a MRTD to the inspection system to prove his or her identity.
The authentication of the traveller is based on (i) the possession of a valid MRTD
personalized for a holder with the claimed identity as given on the biographical data page
and (ii) biometrics using the reference data stored in the MRTD. The issuing State or
Organisation ensures the authenticity of the data of genuine MRTD’s. The receiving State
trusts a genuine MRTD of an issuing State or Organisation.
5 Architectural Information
The TOE consists of hardware and embedded software. The hardware platform of the
TOE is the certified chip P5CD080V0B made by NXP referred to as COMP_CH. The
software is a smartcard operating system with ICAO application. It consists of the in
chapter 1 listed components, which are described in more detail below:
• COMP_KL: The Kernel component manages system's resources and the
communication between components.
• COMP_AD: The Admin component includes the basic administrative functions of
the system. It provides the functionality for creating and deleting objects as well as for
reading and writing within these objects. It also provides the navigation within directory
tree and modification of the object attributes. Furthermore it ensures the observing of
assigned access rights.
• COMP_CR: The Crypt component includes the cryptographic functions of the
system. It grants access to the keys and passwords and provides the functionality for
enciphering, authentication, management of security environment and keys, hash
calculation and signing.
• COMP_IO: The IO component manages the communication between an interface
device and the kernel. This component implements the T=CL protocol and the APDU
syntax check. It does not have a direct access to resources of the other components.
• COMP_TT: The (ROM) TCOS-Type Task includes the ISO-specific code parts.
This component analysis the APDUs and converts them to system-calls for the kernel.
It does not have a direct access to resources of the other components.
• COMP_UT: The User-Type task can contain application depending code. It isn't
used for TCOS Passport and is only listed for completeness. This Task is only valid
inside of this application and can only access objects inside its ADF (Application
13 / 32
Certification Report BSI-DSZ-CC-0506-2008
Dedicated File) and its subdirectories. This code doesn't have direct access to
resources of other components.
6 Documentation
The evaluated documentation as outlined in table 2 is being provided with the product to
the customer. This documentation contains the required information for secure usage of
the TOE in accordance with the Security Target.
Additional obligations and notes for secure usage of the TOE as outlined in chapter 10 of
this report have to be followed.
7 IT Product Testing
Developer tests, independent evaluator tests and penetration tests were performed with
the composite smartcard product TCOS Passport Version 2.0 Release 2-
BAC/P5CD080V0B consisting of the NXP Chip P5CD080V0B, the operational system
TCOS Passport Version 2.0 and three different file systems in the context of the ICAO
application (for details see chapter 8 of this report).
The developer performed functional tests with a TOE in the personalization phase and in
the operational phase. All security functions were tested including their sub-functions. The
test coverage analysis and the test depth analysis gave evidence that the TOE was
systematically tested on the level of the functional specification and on subsystem level.
The test cases are based on the security functionality specified in the functional
specification and showed the conformance to the expected behaviour of the TOE in the
personalization and operational phase. The tests were performed using a smart card
simulator and real chips with the TOE software and the ICAO file-system.
The evaluator repeated developer tests by sampling. The sample covered all security
functions and was performed by using real chips and an emulator. The TOE operated as
specified.
Independent evaluator tests were performed in phase 5 (completion of the smart card
operating system), phase 6 (initialisation and personalization of the MRTD) and in phase 7
(Operational phase of the MRTD) of the TOE. The tests confirmed the expected behaviour
as specified.
The evaluators penetration tests confirmed the effectiveness of all security functions of the
TOE. During these tests the different life cycle phases were considered. The penetration
tests were performed based on the developers vulnerability analysis and based on the
independent vulnerability analysis of the evaluator. Potential vulnerabilities were assessed
upon their exploitability by analysis and tests. Analysis results and tests results showed
that potential vulnerabilities are not exploitable in the intended operational environment of
the TOE and that the TOE is resistant against low attack potential AVA_VLA.2 as
specified.
8 Evaluated Configuration
This certification covers the following configurations of the TOE:
TCOS Passport Version 2.0 Release 2 consists of
• the NXP Chip P5CD080V0B,
14 / 32
BSI-DSZ-CC-0506-2008 Certification Report
• the embedded software operation system TCOS PASSPORT 2.0 (0x21 Version of the
pre-completion code / completion code) and
• one of the following three different file systems in the context of the ICAO application
• (FSV04) In this configuration of the TOE in the dedicated file of the ICAO
application only the files EF.DG1, EF.DG2, EF.SOD, EF.COM and EF.GDO are
visible and empty. Its maximal available memory is already allocated. The access
rules allow access without restrictions. Other EFs are not visible and can not be
initialized during Personalization.
• (FSV05) In this configuration EF.DG1, EF.COM and EF.KEY1 are already initialized
and its memory is assigned too. EFs corresponding to data groups, which are not
necessary for the BAC protocol are not visible and can not be initialized any more.
Other data’s initialization must be done during Personalization, and the access to
these data groups is granted only after successful BAC authentication.
• (FSV03) EF.DG1, EF.COM and EF.KEY1 are already initialized and its memory is
assigned too. But in contrast to the configuration (FSV05) additional data groups
remain non-initialized and must be deactivated during Personalization.
9 Results of the Evaluation
9.1 CC specific results
The Evaluation Technical Report (ETR) [7] was provided by the ITSEF 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.
For components beyond EAL4 the evaluation methodology applied was defined in co-
ordination with the Certification Body [4] (AIS 34).

C Excerpts from the Criteria
CC Part1:
Conformance results (chapter 7.4)
„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 CC Part 2 (functional requirements), CC 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:
CC Part 2 conformant - A PP or TOE is CC Part 2 conformant if the functional
requirements are based only upon functional components in CC Part 2.
CC Part 2 extended - A PP or TOE is CC Part 2 extended if the functional requirements
include functional components not in CC Part 2.
plus one of the following:
CC Part 3 conformant - A PP or TOE is CC Part 3 conformant if the assurance
requirements are based only upon assurance components in CC Part 3.
CC Part 3 extended - A PP or TOE is CC Part 3 extended if the assurance requirements
include assurance requirements not in CC 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 11)
“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 CC 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 11.1)
“Table 6 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 7 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 standard 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.

Certification Report BSI-DSZ-CC-0506-2008
Evaluation assurance level 1 (EAL1) - functionally tested (chapter 11.3)
“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 11.4)
“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
11.5)
“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.”
26 / 32
BSI-DSZ-CC-0506-2008 Certification Report
Evaluation assurance level 4 (EAL4) - methodically designed, tested, and reviewed
(chapter 11.6)
“Objectives
EAL4 permits 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 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
11.7)
“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 11.8)
“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
11.9)
“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 19.3)
“Objectives
27 / 32
Certification Report BSI-DSZ-CC-0506-2008
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 19.4)
"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 Independent vulnerability analysis), moderate (for AVA_VLA.3 Moderately
resistant) or high (for AVA_VLA.4 Highly resistant) attack potential.”
