A Certification
1 Specifications of the Certification Procedure
The certification body conducts the procedure according to the criteria laid down in the
following:
● BSIG2
● BSI Certification Ordinance3
● BSI Schedule of Costs4
● Special decrees issued by the Bundesministerium des Innern (Federal Ministry of the
Interior)
● DIN EN 45011 standard
● BSI certification: Procedural Description (BSI 7125) [3]

2 Recognition Agreements
In order to avoid multiple certification of the same product in different countries a mutual
recognition of IT security certificates - as far as such certificates are based on ITSEC or
CC - under certain conditions was agreed.
2.1 European Recognition of ITSEC/CC – Certificates (SOGIS-MRA)
The SOGIS-Mutual Recognition Agreement (SOGIS-MRA) Version 3 became effective in
April 2010. It defines the recognition of certificates for IT-Products at a basic recognition
level and in addition at higher recognition levels for IT-Products related to certain technical
domains only.
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels
EAL1 to EAL4 and ITSEC Evaluation Assurance Levels E1 to E3 (basic). For higher
recognition levels the technical domain Smart card and similar Devices has been defined.
It includes assurance levels beyond EAL4 resp. E3 (basic).
The new agreement was initially signed by the national bodies of Finland, France,
Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom.

Certification Report BSI-DSZ-CC-0671-2011
Within the terms of this agreement the German Federal Office for Information Security
(BSI) recognises
● for the basic recognition level certificates issued as of April 2010 by the national
certification bodies of France, The Netherlands, Spain and the United Kingdom.
● for the higher recognition level in the technical domain Smart card and similar Devices
certificates issued as of April 2010 by the national certification bodies of France, The
Netherlands and the United Kingdom.
In addition, certificates issued for Protection Profiles based on Common Criteria are part of
the recognition agreement.
The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the
terms of this agreement.
Historically, the first SOGIS-Mutual Recognition Agreement Version 1 (ITSEC only)
became initially effective in March 1998. It was extended in 1999 to include certificates
based on the Common Criteria (MRA Version 2). Recognition of certificates previously
issued under these older versions of the SOGIS-Mutual Recognition Agreement is being
continued.
2.2 International Recognition of CC – Certificates (CCRA)
An arrangement (Common Criteria Recognition Arrangement) on the mutual recognition of
certificates based on the CC Evaluation Assurance Levels up to and including EAL 4 has
been signed in May 2000 (CCRA). It includes also the recognition of Protection Profiles
based on the CC.
As of January 2009 the arrangement has been signed by the national bodies of: Australia,
Austria, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary,
India, Israel, Italy, Japan, Republic of Korea, Malaysia, The Netherlands, New Zealand,
Norway, Pakistan, Republic of Singapore, Spain, Sweden, Turkey, United Kingdom, United
States of America. The current list of signatory nations and approved certification schemes
can be seen on the web site: http://www.commoncriteriaportal.org
The Common Criteria Recognition Arrangement logo printed on the certificate indicates
that this certification is recognised under the terms of this agreement.
This evaluation contains the component ALC_DVS.2 that is not mutually recognised in
accordance with the provisions of the CCRA. For mutual recognition the EAL4
components of these assurance families are relevant.
3 Performance of Evaluation and Certification
The certification body monitors each individual evaluation to ensure a uniform procedure, a
uniform interpretation of the criteria and uniform ratings.
The product MTCOS Pro 2.1 BAC / ST23YR80 has undergone the certification procedure
at BSI. This is a re-certification based on BSI-DSZ-CC-0664-2011. Specific results from
the evaluation process BSI-DSZ-CC-0664-2011 were re-used.
The evaluation of the product MTCOS Pro 2.1 BAC / ST23YR80 was conducted by SRC
Security Research & Consulting GmbH. The evaluation was completed on 11 February
8 / 36
BSI-DSZ-CC-0671-2011 Certification Report
2011. The SRC Security Research & Consulting GmbH is an evaluation facility (ITSEF)6
recognised by the certification body of BSI.
For this certification procedure the sponsor and applicant is:
MaskTech International GmbH.
The product was developed by:
MaskTech International GmbH.
The certification is concluded with the comparability check and the production of this
Certification Report. This work was completed by the BSI.
4 Validity of the Certification Result
This Certification Report only applies to the version of the product as indicated. The
confirmed assurance package is only valid on the condition that
● all stipulations regarding generation, configuration and operation, as given in the
following report, are observed,
● the product is operated in the environment described, where specified in the following
report and in the Security Target.
For the meaning of the assurance levels please refer to the excerpts from the criteria at
the end of the Certification Report.
The Certificate issued confirms the assurance of the product claimed in the Security Target
at the date of certification. As attack methods evolve over time, the resistance of the
certified version of the product against new attack methods needs to be re-assessed.
Therefore, the sponsor should apply for the certified product being monitored within the
assurance continuity program of the BSI Certification Scheme (e.g. by a re-certification).
Specifically, if results of the certification are used in subsequent evaluation and certification
procedures, in a system integration process or if a user's risk management needs regularly
updated results, it is recommended to perform a re-assessment on a regular e.g. annual
basis.
In case of changes to the certified version of the product, the validity can be extended to
the new versions and releases, provided the sponsor applies for assurance continuity (i.e.
re-certification or maintenance) of the modified product, in accordance with the procedural
requirements, and the evaluation does not reveal any security deficiencies.
5 Publication
The product MTCOS Pro 2.1 BAC / ST23YR80 has been included in the BSI list of the

1 Executive Summary
The Target of Evaluation (TOE) is the contactless integrated circuit chip of machine
readable travel documents (MRTD’s chip) programmed according to the Logical Data
Structure (LDS) [20] and providing Basic Access Control, Active Authentication and
Extended Access Control according to the ICAO documents [21] [22] [23] and Chip
Authentication according to the technical report TR-03110 [24].
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 1.10, 25 March 2009, BSI-CC-PP-0055-2009 [7]. Please note that
in consistency to this protection profile only the security mechanism Basic Access Control
was in the focus of the evaluation process. The further security mechanisms Active
Authentication and Extended Access Control as well as Chip Authentication are subjects of
BSI-DSZ-CC-0664-2011 [15].
The TOE Security Assurance Requirements (SAR) 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 ALC_DVS.2.
The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the
Security Target [6] and [8], chapter 6. They are selected from Common Criteria Part 2 and
some of them are newly defined. Thus the TOE is CC Part 2 extended.
The TOE Security Functional Requirements are implemented by the following TOE
Security Functionalities:
TOE Security Functionality Addressed issue
F.IC_CL Security Functions of the Hardware (IC) and
Crypto Library
F.Access_Control Regulates all access by external entities to
operations of the TOE which are only executed
after this TSF allowed access
F.Identification_Authentication Provides identification/authentication of the user
roles
F.Management Provides management and administrative
functionalities
F.Crypto Provides a high level interface to the used
algorithms and implements the used hash
algorithms
F.Verification TOE internal functions to ensure correct
operation
Table 1: TOE Security Functionalities
For more details please refer to the Security Target [6] and [8], chapter 7.
The assets to be protected by the TOE are defined in the Security Target [6] and [8],
chapter 3.1. Based on these assets the TOE Security Problem is defined in terms of
Assumptions, Threats and Organisational Security Policies. This is outlined in the Security
Target [6] and [8], chapter 3.2 to 3.4.

Certification Report BSI-DSZ-CC-0671-2011
The customer specific ROM mask is labelled by STMicroelectronics as K2M0BFB. The
name of the ROM file transferred from MaskTech to STMicroelectronics is
mtcos21b_st23yr80.dlv.
The commercial numbering of the IC embedded software by STMicroelectronics is as
follows:
● Commercial Product Type: SB23YR80BCB4MHBA
● Finished Good Type: 23YR80FCB4MHBASN
The TOE is finalized at the end of phase 2 according to the MRTD EAC PP [7]. Delivery is
performed from the initialization facility to the personalisation facility as a secured transport
to a specific person of contact at the personalization site. The TOE itself will be delivered
as an initialized module but without hardware for contactless interface. The inlay
production including the application of the antenna is not part of the TOE and takes part
after delivery to 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 to start the
personalisation process as described in the User's Guide [11] have to be followed.
3 Security Policy
The Security Policy of the TOE is defined according to the MRTD BAC PP [7] 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). The Security Policy address the advanced security
methods Basic Access Control as well as Chip Authentication and Active Authentication.
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, PKI for Passive Authentication and PKI for Inspection Systems. Details can
be found in the Security Target [6] resp. [8], chapter 3.2.
5 Architectural Information
The TOE is a composite product. It is composed from an Integrated Circuit, IC Embedded
Software and Part Application Software. While the IC Embedded software contains the
operating system MTCOS Pro 2.1, the Part Application Software contains the MRTD
Application. As all these parts of software are running inside the IC, the external interface
of the TOE to its environment can be defined as the external interface of the IC, the
STMicroelectronics SB23YR80B. For details concerning the CC evaluation of the
STMicroelectronics IC see the evaluation documentation under the Certification ID ANSSI-
CC-2010/02 [16]. Please note that the hardware for the contactless interface (I.e. antenna)
is not part of the TOE. The inlay production including the application of the antenna takes
part after delivery.
14 / 36
BSI-DSZ-CC-0671-2011 Certification Report
The Security Functions of the TOE are:
● F.Access_Control
● F.Identification_Authentication
● F.Management
● F.Crypto
● F.Verification
● F.IC_CL
According to the TOE design these Security Functions are enforced by the following
subsystems:
● Application data (supports the TSF F.Access_Control, F.Identification_Authentication)
● Kernel (supports the TSF F.Access_Control, F.Identification_Authentication,
F.Management, F.Crypto, F.Verification)
● HAL (supports the TSF F.Crypto, F.Identification_Authentication, F.Verification)
● Hardware (supports the TSF F.IC_CL)
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
The developer tested all TOE Security Functions either on real cards or with emulator
tests. For all commands and functionality tests, test cases are specified in order to
demonstrate its expected behavior including error cases. Hereby a representative sample
including all boundary values of the parameter set, e.g. all command APDUs with valid and
invalid inputs were tested and all functions were tested with valid and invalid inputs.
Repetition of developer tests were performed during the independent evaluator tests.
Since many Security Functions can be tested by TR-03110 APDU command sequences,
the evaluators performed these tests with real cards. This is considered to be a reasonable
approach because the developer tests include a full coverage of all security functionality.
Furthermore penetration tests were chosen by the evaluators for those Security Functions
where internal secrets of the card could maybe be modified or observed during testing.
During their independent testing, the evaluators covered
● testing APDU commands related to Access Control,
● testing APDU commands related to Identification and Authentication,
● testing APDU commands related to the Secure Messaging Channel,
● penetration testing related to verify the Reliability of the TOE,
● source code analysis performed by the evaluators,
15 / 36
Certification Report BSI-DSZ-CC-0671-2011
● testing the commands which are used to execute the BAC protocol,
● side channel analysis for SHA and ECC,
● fault injection attacks (laser attacks),
● testing APDU commands for the initialization, personalization and usage phase, and
● testing APDU commands for the commands using cryptographic mechanisms.
The evaluators have tested the TOE systematically against enhanced-basic attack
potential during their penetration testing.
The achieved test results correspond to the expected test results.
8 Evaluated Configuration
This certification covers the following configuration of the TOE:
MTCOS Pro 2.1 BAC / ST23YR80 consisting of
● the STMicroelectronics chip SB23YR80B,
● the embedded software, and
● a file system in the context of the ICAO application.
The IC embedded software consists of the operating system MTCOS 2.1 Pro EAC,
including a cryptographic library which supports T-DES, RSA and ECDH (Elliptic Curve
Diffie-Hellman) and an application layer, consisting of the ICAO application.
The customer specific ROM mask is labelled by STMicroelectronics as K2M0BFB. The
name of the ROM file transferred from MaskTech International GmbH to
STMicroelectronics is mtcos21b_st23yr80.dlv.
Since an MRTD may have different file structures here the certified configuration of the
TOE is addressed. The certified configuration of the TOE has 18 different variations due to
three different file system layouts and six different elliptic curve parameter sets (BP224r1,
BP256r1, BP320r1, NISTP224, NISTP256, NISTP384)9
. Thus the TOE consists of the
hardware applied with the 18 different initialisation / pre-personalisation files:
● Dummy-patch8v2-FSP-initscript-LayoutA-BP224r1.txt
● Dummy-patch8v2-FSP-initscript-LayoutA-BP256r1.txt
● Dummy-patch8v2-FSP-initscript-LayoutA-BP320r1.txt
● Dummy-patch8v2-FSP-initscript-LayoutA-NISTP224.txt
● Dummy-patch8v2-FSP-initscript-LayoutA-NISTP256.txt
● Dummy-patch8v2-FSP-initscript-LayoutA-NISTP384.txt
● Dummy-patch8v2-FSP-initscript-LayoutB-BP224r1.txt
● Dummy-patch8v2-FSP-initscript-LayoutB-BP256r1.txt
● Dummy-patch8v2-FSP-initscript-LayoutB-BP320r1.txt
● Dummy-patch8v2-FSP-initscript-LayoutB-NISTP224.txt

Please note that the different elliptic curve sets are only relevant for Extended Access Control (EAC) that
is not part of this Certification. For information about the TOE including the EAC functionality, please
refer to BSI-DSZ-CC-0664-2011 [15].

9 Results of the Evaluation
9.1 CC specific results
The Evaluation Technical Report (ETR) [9] 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 EAL4
extended by advice of the Certification Body for components beyond EAL 4 and guidance
specific for the technology of the product [4] (AIS 34).
The following guidance specific for the technology was used:
● The Application of CC to Integrated Circuits
● Application of Attack Potential to Smartcards
● Public Version of Security Targets (ST-Lite) including JIL Document and CC Supporting
Document and CCRA policies
(see [4], AIS 25, AIS 26, AIS 35).
As a result of the evaluation the verdict PASS is confirmed for the following assurance
components:
● All components of the EAL 4 package including the class ASE as defined in the CC (see
also part C of this report)
● The component ALC_DVS.2 augmented for this TOE evaluation.
As the evaluation work performed for this certification procedure was carried out as a re-
evaluation based on the certificate BSI-DSZ-CC-0664-2011, re-use of specific evaluation
tasks was possible. The focus of this re-evaluation was on the change of the PP
conformance claim from BSI-CC-PP-0056-2009 [25] to BSI-CC-PP-0055-2009 [7]. The
TOE itself did not change.
The evaluation has confirmed:
● PP Conformance: Machine Readable Travel Document with "ICAO Application"

Table 3: Cryptografic Algorithms used by the TOE
The strength of the cryptographic algorithms was not rated in the course of this evaluation
(see BSIG Section 4, Para. 3, Clause 2). According to Technical Guideline BSI-TR-03110,
Version 1.11 [24], the algorithms are suitable for securing originality and confidentiality of
the stored data for machine readable travel documents (MRTDs).
10
The SHA-1 algorithm as well as the following cryptographic algorithms are implemented by the TOE
because of the standards building the TOE application (e.g. TR-03110 [24]). For that reason an explicit
validity period is not given for the SHA-1 and also not for the following cryptographic algorithms.

10 Obligations and Notes for the Usage of the TOE
The documents as outlined in table 2 contain necessary information about the usage of the
TOE and all security hints therein have to be considered. In addition all aspects of
assumptions, threats and policies as outlined in the Security Target not covered by the
TOE itself need to be fulfilled by the operational environment of the TOE.
The customer or user of the product shall consider the results of the certification within his
system risk management process. In order for the evolution of attack methods and
techniques to be covered, he should define the period of time until a re-assessment for the
TOE is required and thus requested from the sponsor of the certificate.
11 Security Target
For the purpose of publishing, the Security Target [8] of the Target of Evaluation (TOE) is
provided within a separate document as Annex A of this report. It is a sanitised version of
the complete Security Target [6] used for the evaluation performed. Sanitisation was
performed according to the rules as outlined in the relevant CCRA policy (see AIS 35 [4]).

C Excerpts from the Criteria
CC Part1:
Conformance Claim (chapter 10.4)
„The conformance claim indicates the source of the collection of requirements that is met
by a PP or ST that passes its evaluation. This conformance claim contains a CC
conformance claim that:
● describes the version of the CC to which the PP or ST claims conformance.
● describes the conformance to CC Part 2 (security functional requirements) as either:
– CC Part 2 conformant - A PP or ST is CC Part 2 conformant if all SFRs in that
PP or ST are based only upon functional components in CC Part 2, or
– CC Part 2 extended - A PP or ST is CC Part 2 extended if at least one SFR in
that PP or ST is not based upon functional components in CC Part 2.
● describes the conformance to CC Part 3 (security assurance requirements) as either:
– CC Part 3 conformant - A PP or ST is CC Part 3 conformant if all SARs in that
PP or ST are based only upon assurance components in CC Part 3, or
– CC Part 3 extended - A PP or ST is CC Part 3 extended if at least one SAR in
that PP or ST is not based upon assurance components in CC Part 3.
Additionally, the conformance claim may include a statement made with respect to
packages, in which case it consists of one of the following:
● Package name Conformant - A PP or ST is conformant to a pre-defined package
(e.g. EAL) if:
– the SFRs of that PP or ST are identical to the SFRs in the package, or
– the SARs of that PP or ST are identical to the SARs in the package.
● Package name Augmented - A PP or ST is an augmentation of a predefined package
if:
– the SFRs of that PP or ST contain all SFRs in the package, but have at least
one additional SFR or one SFR that is hierarchically higher than an SFR in the
package.
– the SARs of that PP or ST contain all SARs in the package, but have at least
one additional SAR or one SAR that is hierarchically higher than an SAR in the
package.
Note that when a TOE is successfully evaluated to a given ST, any conformance claims of
the ST also hold for the TOE. A TOE can therefore also be e.g. CC Part 2 conformant.
Finally, the conformance claim may also include two statements with respect to Protection
Profiles:
● PP Conformant - A PP or TOE meets specific PP(s), which are listed as part of the
conformance result.
● Conformance Statement (Only for PPs) - This statement describes the manner in
which PPs or STs must conform to this PP: strict or demonstrable. For more
information on this Conformance Statement, see Annex D.”

Evaluation assurance levels (chapter 8)
“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 8.1)
“Table 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 7 of this CC 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 augmented with extended
assurance requirements.

28 / 36
BSI-DSZ-CC-0671-2011 Certification Report
Evaluation assurance level 1 (EAL1) - functionally tested (chapter 8.3)
“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 requires only a limited security target. It is sufficient to simply state the SFRs that the
TOE must meet, rather than deriving them from threats, OSPs and assumptions through
security objectives.
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.”
Evaluation assurance level 2 (EAL2) - structurally tested (chapter 8.4)
“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 practise. 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 8.5)
“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 practises.
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.”
29 / 36
Certification Report BSI-DSZ-CC-0671-2011
Evaluation assurance level 4 (EAL4) - methodically designed, tested, and reviewed
(chapter 8.6)
“Objectives
EAL4 permits a developer to gain maximum assurance from positive security engineering
based on good commercial development practises 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 8.7)
“Objectives
EAL5 permits a developer to gain maximum assurance from security engineering based
upon rigorous commercial development practises 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 8.8)
“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.”
30 / 36
BSI-DSZ-CC-0671-2011 Certification Report
Evaluation assurance level 7 (EAL7) - formally verified design and tested
(chapter 8.9)
“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.”
Class AVA: Vulnerability assessment (chapter 16)
“The AVA: Vulnerability assessment class addresses the possibility of exploitable
vulnerabilities introduced in the development or the operation of the TOE.”
Vulnerability analysis (AVA_VAN) (chapter 16.1)
"Objectives
Vulnerability analysis is an assessment to determine whether potential vulnerabilities
identified, during the evaluation of the development and anticipated operation of the TOE
or by other methods (e.g. by flaw hypotheses or quantitative or statistical analysis of the
security behaviour of the underlying security mechanisms), could allow attackers to violate
the SFRs.
Vulnerability analysis deals with the threats that an attacker will be able to discover flaws
that will allow unauthorised access to data and functionality, allow the ability to interfere
with or alter the TSF, or interfere with the authorised capabilities of other users.”
