Table 2: Deliverables of the TOE
The TOE is finalized at the end of phase 2 according to the Protection Profile MRTD BAC
PP [10].
Delivery is performed from the initialization facility (MaskTech International GmbH,
Nordostpark 16, 90411 Nuremberg, Germany) to the personalization facility by as a
secured transport to a specific person of contact at the personalization site. Furthermore,
the personalizer receives information about the personalization commands and process
requirements. To ensure that the personalizer receives this evaluated version, the
procedures as described in the MTCOS Pro 2.0 ICAO User Guidance [15] have to be
followed.
3 Security Policy
The Security Policy of the TOE is defined according to the MRTD BAC PP [10] 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 defined in the Security Target and some aspects of Threats and
Organisational Security Policies are not covered by the TOE itself. These aspects lead to
specific Security Objectives to be fulfilled by the TOE- Environment. The following topics
are of relevance:
● Personalization of the MRTD’s chip,
● Inspection Systems for global interoperability.
Details can be found in the Security Target [6] resp. [9], chapter 3.2.
5 Architectural Information
The TOE is an RFID device according to ICAO technical reports [11] and [12] supporting
Basic Access Control. It is implemented as an embedded software on a smart card chip, in
this case the CC EAL 5+ certified ST Microelectronics ST19NR66 rev. B secure dual-
interface controller.
14 / 34
BSI-DSZ-CC-0492-2008 Certification Report
The TOE comprises
● the circuitry of the MRTD’s chip (the integrated circuit, IC) with hardware for the
contactless interface, e.g. antennae, capacitors
● the IC Dedicated Software with the parts IC Dedicated Test Software and IC Dedicated
Support Software
● the IC Embedded Software (operating system MTCOS Pro 2.0, Version 8.0)
● the MRTD application (dedicated file for the ICAO application in a file system on the
chip) and
● the associated guidance documentation.
The TOE provides following services for MRTDs:
● Storage of the MRTD data, e. g. data groups and signature.
● Organization of the data in a file system as dedicated and elementary files.
● Mutual Authentication and Secure Messaging as specified in TrPKI [12] for Basic
Access Control.
● Contactless communication according to ISO/IEC 14443.
● Protection of data against modification.
● Protection of the privacy of the passport holder with functions like random UID and
Basic Access Control.
The TSF of the software uses the hardware via evaluated hardware interfaces. External
interface of the composite TOE used in the MRTD application is a specific set of
commands operating on a defined file-system of the application. This interface is available
to the inspection system via the contactless chip interface.
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 using
MRTD chips MTCOS Pro 2.0 ICAO composed of the the ST Microelectronics ST19NR66
rev. B secure dual-interface controller, its dedicated software, the operating system
MTCOS Pro 2.0 and a file-system for the ICAO application. TOEs in the configuration LDS
(Logical Data Structure) and BAC (Basic Access Control) were tested.
The developer performed functional tests with a TOE in the personalization phase and in
the operational phase. All security functions were tested including their subfunctions. 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.
15 / 34
Certification Report BSI-DSZ-CC-0492-2008
The test cases based on the security functionality specified in the functional specification
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. The TOE operated as specified.
Independent evaluator tests were performed during completion of the smart card operating
system, initialisation and personalization of the MRTD and the operational phase of the
MRTD. 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:
MTCOS Pro 2.0 ICAO / ST19NR66 consisting of
● the ST Microelectronics ST19NR66 rev. B secure dual-interface controller
● the embedded software operation system MTCOS Pro 2.0 (Version 8.0) and
● a file system in the context of the ICAO application.
The TOE is delivered in form of an initialised and tested inlay module. This corresponds to
the end of life cycle phase 2 as described in the Protection Profile MRTD BAC PP [10].
All procedures for personalisation and configuration for the end-user necessary after
delivery are described in the Guidance document [15].
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.
The Evaluation Methodology CEM [2] was used for those components up to EAL 4
extended by advice of the Certification Body for components beyond EAL 4 and guidance
specific for the technology of the product [4] (AIS 34).
As a result of the evaluation the verdict PASS is confirmed for the following assurance
components:
● All components of the class ASE
● All components of the EAL 4 package as defined in the CC (see also part C of this
report)
16 / 34
BSI-DSZ-CC-0492-2008 Certification Report
● The components
ADV_IMP.2 – Implementation of the TSF
ALC_DVS.2 – Sufficiency of security measures
augmented for this TOE evaluation.
The evaluation has confirmed:
● PP Conformance: Machine Readable Travel Document with "ICAO Application",
Basic Access Control, BSI-PP-0017-2005 [10]
● for the Functionality: PP conformant
Common Criteria Part 2 extended
● for the Assurance: Common Criteria Part 3 conformant
EAL 4 augmented by
ADV_IMP.2 and ALC_DVS.2
● The following TOE Security Functions fulfil the claimed Strength of Function: high
SF_ALEAS_A - Unpredictable Number Generation Support
SF_SKCS_A - Symmetric Key Cryptography Support
F.Identification_Authentication - Identification and Authentication of user roles
F.Secure_Messaging - Implementation of a secure communication channel
For specific evaluation results regarding the development and production environment see
annex B in part D of this report.
The results of the evaluation are only applicable to the TOE as defined in chapter 2 and
the configuration as outlined in chapter 8 above.
9.2 Results of cryptographic assessment
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). This holds for:
● SF_ALEAS_A - Unpredictable Number Generation Support
● SF_SKCS_A - Symmetric Key Cryptography Support
● F.Identification_Authentication - Identification and Authentication of user roles
● F.Secure_Messaging - Implementation of a secure communication channel
10 Obligations and notes for the usage of the TOE
The operational documents [15], [16]. [17] and [18] contain necessary information about
the usage of the TOE and all security hints therein have to be considered.
The TOEs implemented security functions meet the claimed strength of function SOF-high
from design and construction point of view. The strength of function available in a specific
system context where the TOE is used depends on the selection of the data used to set up
the communication to the TOE. Therefore the issuing state or organisation is responsible
for the strength of function that can be achieved in a specific system context. This has to
be assessed in the specific system context. Then, the administrator (personalizer) is in
collaboration with the issuing state or organisation responsible to provide keys with
sufficient entropy, as required by the specific system context.
17 / 34
Certification Report BSI-DSZ-CC-0492-2008
Only chips from the production sites (waferfabs, module and inlay production sites) as
outlined in the certification report for the ST Microelectronics ST19NR66 rev. B secure

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-0492-2008
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.”
28 / 34
BSI-DSZ-CC-0492-2008 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.”
29 / 34
Certification Report BSI-DSZ-CC-0492-2008
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
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.”
