Preliminary Remarks
Under the BSIG1
Act, the Federal Office for Information Security (BSI) has the task of
issuing certificates for information technology products.
Certification of a product is carried out on the instigation of the vendor or a distributor,
hereinafter called the sponsor.
A part of the procedure is the technical examination (evaluation) of the product according
to the security criteria published by the BSI or generally recognised security criteria.
The evaluation is normally carried out by an evaluation facility recognised by the BSI or by
BSI itself.
The result of the certification procedure is the present Certification Report. This report
contains among others the certificate (summarised assessment) and the detailed
Certification Results.
The Certification Results contain the technical description of the security functionality of
the certified product, the details of the evaluation (strength and weaknesses) and
instructions for the user.

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 SOGIS
Technical Domains only.

Certification Report BSI-DSZ-CC-0782-V3-2017
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels
EAL 1 to EAL 4 and ITSEC Evaluation Assurance Levels E1 to E3 (basic). For
"Smartcards and similar devices" a SOGIS Technical Domain is in place. For "HW Devices
with Security Boxes" a SOGIS Technical Domains is in place, too. In addition, certificates
issued for Protection Profiles based on Common Criteria are part of the recognition
agreement.
The new agreement has been signed by the national bodies of Austria, Finland, France,
Germany, Italy, The Netherlands, Norway, Spain, Sweden and the United Kingdom. The
current list of signatory nations and approved certification schemes, details on recognition,
and the history of the agreement can be seen on the website at https://www.sogisportal.eu.
The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the
terms of this agreement by the nations listed above.
This certificate is recognized under SOGIS-MRA for all assurance components selected.
2.2. International Recognition of CC – Certificates (CCRA)
The international arrangement on the mutual recognition of certificates based on the CC
(Common Criteria Recognition Arrangement, CCRA-2014) has been ratified on 08
September 2014. It covers CC certificates based on collaborative Protection Profiles (cPP)
(exact use), CC certificates based on assurance components up to and including EAL 2 or
the assurance family Flaw Remediation (ALC_FLR) and CC certificates for Protection
Profiles and for collaborative Protection Profiles (cPP).
The CCRA-2014 replaces the old CCRA signed in May 2000 (CCRA-2000). Certificates
based on CCRA-2000, issued before 08 September 2014 are still under recognition
according to the rules of CCRA-2000. For on 08 September 2014 ongoing certification
procedures and for Assurance Continuity (maintenance and re-certification) of old
certificates a transition period on the recognition of certificates according to the rules of
CCRA-2000 (i.e. assurance components up to and including EAL 4 or the assurance
family Flaw Remediation (ALC_FLR)) is defined until 08 September 2017.
As of September 2014 the signatories of the new CCRA-2014 are government
representatives from the following nations: Australia, Austria, Canada, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, India, Israel, Italy, Japan,
Malaysia, The Netherlands, New Zealand, Norway, Pakistan, Republic of Korea,
Singapore, Spain, Sweden, Turkey, United Kingdom, and the United States.
The current list of signatory nations and approved certification schemes can be seen on
the website: 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 by the nations listed
above.
As this certificate is a re-certification of a certificate issued according to CCRA-2000 this
certificate is recognized according to the rules of CCRA-2000, i.e. up to and including CC
part 3 EAL 4 components. The evaluation contained the components ADV_FSP.5,
ADV_IMP.2, ADV_INT.3, ADV_SPM.1, ADV_TDS.5, ALC_CMC.5, ALC_CMS.5,
ALC_DVS.2, ALC_TAT.3, ATE_COV.3, ATE_DPT.3, ATE_FUN.2 that are not mutually
recognised in accordance with the provisions of the CCRA-2000, for mutual recognition
the EAL 4 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 Infineon Security Controller M7892 B11 with optional RSA2048/4096
v1.02.013, EC v1.02.013, SHA-2 v1.01, SCL v2.02.012, Base v1.02.013, and Toolbox
v1.02.013 libraries and with specific IC dedicated software (firmware) has undergone the
certification procedure at BSI. This is a re-certification based on BSI-DSZ-CC-0782-V2-
2015. Specific results from the evaluation process BSI-DSZ-CC-0782-V2-2015 were re-
used.
The evaluation of the product Infineon Security Controller M7892 B11 with optional
RSA2048/4096 v1.02.013, EC v1.02.013, SHA-2 v1.01, SCL v2.02.012, Base v1.02.013,
and Toolbox v1.02.013 libraries and with specific IC dedicated software (firmware) was
conducted by TÜV Informationstechnik GmbH. The evaluation was completed on 30
August 2017. TÜV Informationstechnik GmbH is an evaluation facility (ITSEF)6
recognised
by the certification body of BSI.
For this certification procedure the sponsor and applicant is: Infineon Technologies AG.
The product was developed by: Infineon Technologies AG.
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, as 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 or in the CC itself.
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 order to avoid an indefinite usage of the certificate when evolved attack methods require
a re-assessment of the products resistance to state of the art attack methods, the
maximum validity of the certificate has been limited. The certificate issued on 5 September
2017 is valid until 4 September 2022. Validity can be re-newed by re-certification.

1. Executive Summary
The Target of Evaluation (TOE) is the Infineon Security Controller M7892 B11 with optional
RSA2048/4096 v1.02.013, EC v1.02.013, SHA-2 v1.01, SCL v2.02.012, Base v1.02.013,
and Toolbox v1.02.013 libraries and with specific IC dedicated software (firmware). The
TOE provides a real 16-bit CPU-architecture and is compatible to the Intel 80251
architecture. The major components of the core system are the dual CPU (Central
Processing Units), the MMU (Memory Management Unit) and MED (Memory
Encryption/Decryption Unit). The dual interface controller is able to communicate using
either the contact based or the contactless interface.
The TOE consists of a hardware, a firmware and a software part. The software part can be
separated into the cryptographic libraries SCL, RSA, EC and SHA-2, as well as the
supporting libraries Toolbox and Base. The SCL, RSA, EC, SHA-2 and Toolbox libraries
provide the smartcard embedded software with specific functionalities.
This TOE is intended to be used in smart cards for particularly security relevant
applications and for its previous use as developing platform for smart card operating
systems. The term Smartcard Embedded Software is used in the following for all operating
systems and applications stored and executed on the TOE. The TOE is the platform for the
Smartcard Embedded Software.
The Security Target [6] is the basis for this certification. It is based on the certified
Protection Profile Security IC Platform Protection Profile, Version 1.0, 15 June 2007, BSI-
CC-PP-0035-2007 [8].
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 6
augmented by ALC_FLR.1.
The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the
Security Target [6] and [9], chapter 7. 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 Functionality:
TOE Security Functionality Addressed issue
SF_DPM Device Phase Management
SF_PS Protection against Snopping
SF_PMA Protection against Modification Attacks
SF_PLA Protection against Logical Attacks
SF_CS Cryptographic Support
Table 1: TOE Security Functionalities
For more details please refer to the Security Target [6] and [9], chapter 8 (TOE Summary
Specification).
The assets to be protected by the TOE are defined in the Security Target [6] and [9],
chapter 4.1.2. Based on these assets the TOE Security Problem is defined in terms of
12 / 40
BSI-DSZ-CC-0782-V3-2017 Certification Report
Assumptions, Threats and Organisational Security Policies. This is outlined in the Security
Target [6] and [9], chapter 4.3, 4.1 and 4.2, respectively.
This certification covers the configurations of the TOE as outlined in chapter 8.
The vulnerability assessment results as stated within this certificate do not include a rating
for those cryptographic algorithms and their implementation suitable for encryption and
decryption (see BSIG Section 9, Para. 4, Clause 2).
The certification results only apply to the version of the product indicated in the certificate
and on the condition that all the stipulations are kept as detailed in this Certification
Report. This certificate is not an endorsement of the IT product by the Federal Office for
Information Security (BSI) or any other organisation that recognises or gives effect to this
certificate, and no warranty of the IT product by BSI or any other organisation that
recognises or gives effect to this certificate, is either expressed or implied.

BSI-DSZ-CC-0782-V3-2017 Certification Report
The individual TOE hardware is uniquely identified by its identification data. The
identification data contains the lot number, the wafer number and the coordinates of the
chip on the wafer. Each individual TOE can therefore be traced unambiguously and thus
assigned to the entire development and production process.
The hardware part of the TOE is identified by M7892 B11. Another characteristic of the
TOE are the chip identification data. These chip identification data is accessible via the
Generic Chip Identification Mode (GCIM).
This GCIM outputs a variety of unique information in order to uniquely determine the
underlying hardware configuration. Additionally, a dedicated RMS function (see [15]
section 9.16) allows a customer to extract the present hardware configuration and the
original Chip Identifier Byte, which was valid before blocking.
The firmware part of the TOE is also identified also via the GCIM for all of the firmware
parts STS, RMS, SAM, FL, and Mifare.
The SCL (optional), RSA (optional), EC (optional), SHA-2 (optional), Toolbox (optional),
and Base library (optional), as separate software parts of the TOE, are also identified by
their unique version numbers. The user can identify these versions by calculating the hash
signatures of the provided library files. The mapping of these hash signatures to the
version numbers is provided in the Security Target [6] and [9] section 10.
Please also note, that as the TOE is under control of the user software, the TOE
Manufacturer can only guarantee the integrity up to the delivery procedure. It is in the
responsibility of the Composite Product Manufacturer to include mechanisms in the
implemented software (developed by the IC Embedded Software Developer) which allows
detection of modifications after the delivery.
3. Security Policy
The security policy is expressed by the given set of Security Functional Requirements and
implemented by the TOE. It covers the following issues:
The Security Policy of the TOE is to provide basic security functionalities to be used by the
smart card operating system and the smart card application, thus providing an overall
smart card system security. Therefore, the TOE implements a symmetric cryptographic
block cipher algorithm (Triple-DES and AES) to ensure the confidentiality of plain text data
by encryption and to support secure authentication protocols and it will provide a True
Random Number Generator (TRNG).
The SCL uses the symmetric cryptographic co-processor (SCP) of the hardware to provide
the user with a software interface to the TDES and AES calculations and adds
countermeasures against leakage and fault attacks.
The RSA library is used to provide a high level interface to RSA (Rivest, Shamir, Adleman)
cryptography implemented on the hardware component Crypto@2304T and includes
countermeasures against SPA, DPA and DFA attacks. The EC library is used to provide a
high level interface to Elliptic Curve cryptography implemented on the hardware
component Crypto@2304T and includes countermeasures against SPA, DPA and DFA
attacks. The SHA-2 library provides the calculation of a hash value of freely chosen data
input in the CPU.
As the TOE is a hardware security platform, the security policy of the TOE is also to
provide protection against leakage of information (e.g. to ensure the confidentiality of
cryptographic keys during AES, Triple-DES, RSA and EC cryptographic functions
15 / 40
Certification Report BSI-DSZ-CC-0782-V3-2017
performed by the TOE), against physical probing, against malfunctions, against physical
manipulations and against abuse of functionality. Hence the TOE shall
● maintain the integrity and the confidentiality of data stored in the memory of the TOE
and
● maintain the integrity, the correct operation and the confidentiality of security
functionalities (security mechanisms and associated functions) provided by the TOE.
Specific details concerning the above mentioned security policies can be found in the
Security Target [6] and [9], chapter 7.
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 and measures to be taken by the IT environment
and the user or the risk manager. The following topics are of relevance:
The ST only includes two security objective for the IC Embedded Software Developer, the
objectives OE.Plat-Appl and OE.Resp-Appl.
The objective OE.Plat-Appl states that the IC Embedded Software Developer shall design
his software so that the requirements from the data sheet, the TOE application notes, other
guidance documents and findings of the TOE evaluation report are implemented. As all
these documents ([12] - [20]) are identified as parts of the TOE and delivered to the IC
Embedded Software Developer, the objective OE.Plat-Appl is fulfilled.The objective
OE.Resp-Appl states that the IC Embedded Software Developer shall treat user data
(especially keys) appropriately. The IC Embedded Software Developer gets sufficient
information on how to protect user data adequate in the security guidelines [M7892_Sec].
Details can be found in the Security Target [6] and [9], chapters 5.2.1 and 5.2.2.
5. Architectural Information
The TOE is an integrated circuit (IC) providing a platform for an operating sytem and
application software used in smartcards but also in any other device or form factor
requiring a high level of resistance against attackers. A top level block diagram and a list of
subsystems can be found within the TOE description of the Security Target [6], chapter
2.1.
The TOE provides a real 16-bit CPU-architecture and is compatible to the Intel 80251
architecture. The major components of the core system are the two CPUs (Central
Processing Units), the MMU (Memory Management Unit) and MED (Memory
Encryption/Decryption Unit). The two CPUs control each other in order to detect faults and
serve by this for data integrity. The TOE implements a full 16 MByte linear addressable
memory space for each privilege level, a simple scalable Memory Management concept
and a scalable stack size. The flexible memory concept consists of ROM- and Flash-
memory as part of the non volatile memory (NVM), respectively Infineon SOLID FLASH™.
For the Infineon SOLID FLASH™ memory the Unified Channel Programming (UCP)
memory technology is used. Note that there is no user available on-chip ROM module
anymore. The user software and data are now located in a dedicated and protected part of
the Infineon SOLID FLASH™.

The two cryptographic co-processors serve the need of modern cryptography: The
symmetric co-processor (SCP) combines both AES and Triple-DES with dual-key or triple-
key hardware acceleration. The Asymmetric Crypto Co-processor, called Crypto2304T in
the following, is an optimized version of the Crypto@1408 used in the SLE88-family with
performance improvements for RSA-2048 bit (4096-bit with CRT) and Elliptic Curve (EC)
cryptography.
The software part of the TOE consists of the cryptographic RSA-, EC-, SCL- and the SHA-
2 libraries and the supporting Toolbox and Base libraries. If RSA or EC or Toolbox or
combinations hereof are part of the shipment, automatically the Base Library is included.
The Flash Loader is a firmware located in the ROM (Read-Only Memory; patch in NVM)
and enables the download of the user software or parts of it to the Infineon SOLID
FLASH™ memory. After completion of the download the Flash Loader shall be locked by
the by the user.
For more details please refer to the Security Target [6] and [9], chapters 1.2 and 2.2.2.
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 tests performed by the developer were divided into five categories:
● Simulation tests (design verification),
● Qualification tests,
● Verification Tests,
● Security Evaluation Tests,
● Production Tests.
The developer tests cover all security functionalities and all security mechanisms as
identified in the security architecture description.
The evaluators were able to repeat the tests of the developer either using the library of
programs, tools and prepared chip samples delivered to the evaluator or at the developer’s
site. They performed independent tests to supplement, augment and to verify the tests
performed by the developer. For the developer tests repeated by the evaluators other test
parameters were used and the test equipment was varied. Security features of the TOE
realised by specific design and layout measures were checked by the evaluators during
layout inspections both in design data and on the final product.
The evaluation has shown that the actual version of the TOE provides the security
functionalities as specified by the developer. The test results confirm the correct
implementation of the TOE security functionalities.
For penetration testing the evaluators took all security functionalities into consideration.
Intensive penetration testing was planned based on the analysis results and performed for
17 / 40
Certification Report BSI-DSZ-CC-0782-V3-2017
the underlying mechanisms of security functionalities. The penetration tests considered
both the physical tampering of the TOE and attacks which do not modify the TOE
physically. The penetration tests results confirm that the TOE is resistant to attackers with
high attack potential in the intended environment for the TOE.
8. Evaluated Configuration
This certification covers the following configurations of the TOE:
● Security Controller M7892 B11 (produced in Dresden).
Depending on the blocking configuration a M7892 product can have a different user
available configuration as described in Security Target [6] and [9], chapter 1.1 and 1.2.
The available options are summed up in the Security Target [6] and [9], section 1.2:
● The available memory sizes of the SOLID FLASH™ NVM and RAM. Note that there is
no user available ROM on the TOE,
● The availability of the cryptographic coprocessors,
● The availability and free combinations of the cryptographic libraries,
● The availability of the Flash Loader for available interfaces like ISO-7816, contactless
ISO-14443,
● The availability of various interface options,
● The possibility to tailor the product by blocking on his own premises,
● The degree of freedom of the chip configuration is predefined by Infineon Technologies
AG and made available via the order tool.
All possible TOE configurations are covered by the certificate. Note that there is no user
available on-chip ROM module any more. The user software and data are now located in a
dedicated and protected part of the SOLID FLASH™. According to the BPU option, a non
limited number of configurations of the TOE may occur in the field. The number of various
configurations depends on the order and purchase contract only.
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 5
extended by advice of the Certification Body for components beyond EAL 5 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
● The Application of Attack Potential to Smartcards
● Functionality classes and evaluation methodology of physical random number
generators
18 / 40
BSI-DSZ-CC-0782-V3-2017 Certification Report
For RNG assessment the scheme interpretations AIS 31 was used (see [4], AIS 25, AIS
26, AIS 31).
To support composite evaluations according to AIS 36 the document ETR for composite
evaluation [10] was provided and approved. This document provides details of this
platform evaluation that have to be considered in the course of a composite evaluation on
top.
The assurance refinements outlined in the Security Target were followed in the course of
the evaluation of the TOE.
As a result of the evaluation the verdict PASS is confirmed for the following assurance
components:
● All components of the EAL 6 package including the class ASE as defined in the CC (see
also part C of this report)
● The components ALC_FLR.1 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-0782-V2-2015, re-use of specific
evaluation tasks was possible. The focus of this re-evaluation was on a newly included
symmetric crypto library (SCL) and adjustments regarding crypto security functionality.
The evaluation has confirmed:
● PP Conformance: Security IC Platform Protection Profile, Version 1.0, 15 June
2007, BSI-CC-PP-0035-2007 [8]
● for the Functionality: PP conformant plus product specific extensions
Common Criteria Part 2 conformant extended
● for the Assurance: Common Criteria Part 3 conformant
EAL 6 augmented by ALC_FLR.1
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 strength of the cryptographic algorithms was not rated in the course of this certification
procedure (see BSIG Section 9, Para. 4, Clause 2). But Cryptographic Functionalities with
a security level of lower than 100 bits can no longer be regarded as secure without
considering the application context. Therefore, for these functionalities it shall be checked
whether the related crypto operations are appropriate for the intended system. Some
further hints and guidelines can be derived from the 'Technische Richtlinie BSI TR-02102'
(https://www.bsi.bund.de).
The Security Target [6] and [9] (table 17 therein) provides a table detailing the available
cryptographic functionality.
Any Cryptographic Functionality that is marked in column 'Security Level above 100 Bits'
of the following table with 'no' achieves a security level of lower than 100 Bits (in general
context).

Certification Report BSI-DSZ-CC-0782-V3-2017
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 OSPs 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 of the
TOE is required and thus requested from the sponsor of the certificate.
The limited validity for the usage of cryptographic algorithms as outlined in chapter 9 has
to be considered by the user and his system risk management process.
Some security measures are partly implemented in this certified TOE, but require
additional configuration or control or measures to be implemented by a product layer on
top, e.g. the IC Dedicated Support Software or Embedded Software using the TOE. For
this reason the TOE includes guidance documentation (see table 2) which contains
obligations and guidelines for the developer of the product layer on top on how to securely
use this certified TOE and which measures have to be implemented in order to fulfil the
security requirements of the Security Target of the TOE. In the course of the evaluation of
the composite product or system it must be examined if the required measures have been
correctly and effectively implemented by the product layer on top. Additionally, the
evaluation of the composite product or system must also consider the evaluation results as
outlined in the document ETR for composite evaluation [10].
In addition, the following aspects need to be fulfilled when using the TOE:
● All security hints described in the delivered documents [12] to [20] have to be
considered.
The Composite Product Manufacturer receives all necessary recommendations and hints
to develop his software in form of the delivered documentation.
● All security hints described in [21] have to be considered.
In addition the following hint resulting from the evaluation of the ALC evaluation aspect has
to be considered:
● The IC Embedded Software Developer can deliver his software either to Infineon to let
them implement it in the TOE (in Flash memory) or to the Composite Product
Manufacturer to let him download the software in the Flash memory.
● The delivery procedure from the IC Embedded Software Developer to the Composite
Product Manufacturer is not part of this evaluation and a secure delivery is required.
11. Security Target
For the purpose of publishing, the Security Target [9] 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 Part 1:
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.”

“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
30 / 40
BSI-DSZ-CC-0782-V3-2017 Certification Report
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.
Evaluation assurance level 1 (EAL 1) - functionally tested (chapter 8.3)
“Objectives
EAL 1 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.
EAL 1 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.
EAL 1 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 EAL 1 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 (EAL 2) - structurally tested (chapter 8.4)
“Objectives
EAL 2 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.
EAL 2 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 (EAL 3) - methodically tested and checked (chapter 8.5)
“Objectives
EAL 3 permits a conscientious developer to gain maximum assurance from positive
security engineering at the design stage without substantial alteration of existing sound
development practises.
31 / 40
Certification Report BSI-DSZ-CC-0782-V3-2017
EAL 3 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 (EAL 4) - methodically designed, tested, and reviewed
(chapter 8.6)
“Objectives
EAL 4 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. EAL 4 is the highest level at
which it is likely to be economically feasible to retrofit to an existing product line.
EAL 4 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 (EAL 5) - semiformally designed and tested (chapter
8.7)
“Objectives
EAL 5 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 EAL 5 assurance. It is likely that the additional costs
attributable to the EAL 5 requirements, relative to rigorous development without the
application of specialised techniques, will not be large.
EAL 5 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 (EAL 6) - semiformally verified design and tested
(chapter 8.8)
“Objectives
EAL 6 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.
EAL 6 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 (EAL 7) - formally verified design and tested
(chapter 8.9)
“Objectives
EAL 7 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 EAL 7 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.”
