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-0946-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 ALC_DVS.2,
AVA_VAN.5, ADV_FSP.5, ADV_INT.2, ADV_TDS.4, ALC_CMS.5, ALC_TAT.2 and
ATE_DPT.3 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 Technologies Smart Card IC (Security Controller) M5072 with
optional RSA v1.03.006/v2.06.003, EC v1.03.006/ v2.06.003, Toolbox v1.03.006/
v2.06.003, SCL v2.02.010 libraries with specific IC dedicated software has undergone the
certification procedure at BSI. This is a re-certification based on BSI-DSZ-CC-0946-V2-
2015. Specific results from the evaluation process BSI-DSZ-CC-0946-V2-2015 were re-
used.
The evaluation of the product Infineon Technologies Smart Card IC (Security Controller)
M5072 with optional RSA v1.03.006/v2.06.003, EC v1.03.006/ v2.06.003, Toolbox
v1.03.006/ v2.06.003, SCL v2.02.010 libraries with specific IC dedicated software was
conducted by TÜV Informationstechnik GmbH. The evaluation was completed on 27 July
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 18 August
2017 is valid until 17 August 2022. Validity can be re-newed by re-certification.

1. Executive Summary
This is a re-evaluation of the certification BSI-DSZ-CC-0946-V2-2015.
The Target of Evaluation (TOE) is Infineon Technologies Smart Card IC (Security
Controller) M5072 with optional RSA v1.03.006/v2.06.003, EC v1.03.006/ v2.06.003,
Toolbox v1.03.006/ v2.06.003, SCL v2.02.010 libraries with specific IC dedicated software.
The TOE provides a real 32-bit CPU-architecture and is compatible to the ARMv7-M
instruction set. The major components of the core system are the 32-bit CPU (Central
Processing Unit), the Cache system, the MPU (Memory Protection Unit) and the MED
(Memory Encryption/Decryption Unit).
The TOE consists of the hardware part, the firmware parts and the software parts. The
software parts are differentiated into: the asymmetric cryptographic libraries RSA and EC
and the symmetric cryptographic library SCL for DES and AES.
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.
In comparison to the previous certification (BSI-DSZ-CC-0946-V2-2015), the TOE is
identical with the exceptions of:
● a new version (v2.06.003) of the RSA, EC, Toolbox and Base library has been
introduced,
● addition of the symmetric crypto library (SCL) v2.02.010,
● The RSA key generation (FCS_CKM.1/RSA) is now optional/conditional, in dependence
of the RSA library version,
● new guidance documentation.
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 5
augmented by ALC_DVS.2 and AVA_VAN.5.
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:
The life cycle of the TOE is split up into several
phases. Different operation modes help to protect
the TOE during each phase of its lifecycle.
12 / 42
BSI-DSZ-CC-0946-V3-2017 Certification Report
TOE Security Functionality Addressed issue
SF_PS Protection against Snooping:
The TOE uses various means to protect from
snooping of vital TOE parts.
SF_PMA Protection against Modifying Attacks:
This TOE implements protection against
modifying attacks of vital TOE parts.
SF_PLA Protection against Logical Attacks.
SF_CS Cryptographic Support:
The TOE is equipped with several hardware
accelerators and software modules to support the
standard symmetric and asymmetric
cryptographic operations. Additionally the TOE is
equipped with a True Random Number Generator
for the generation of random numbers.
Table 1: TOE Security Functionalities
For more details please refer to the Security Target [6] and [9], chapter 8.
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
Assumptions, Threats and Organisational Security Policies. This is outlined in the Security
Target [6] and [9], chapters 4.3, 4.1 and 4.2 (respectively).
Regarding the firmware the user has the possibility to choose between different firmware
versions (80001141, 80001144 or 80001145). Depending on the blocking configuration the
TOE can have different user available configuration by order or by BPU.
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.

Table 2: Deliverables of the TOE
The delivery procedures follow the user demands, meaning that the user defines the
procedures applied for delivery. These procedures include, but are not limited to, selection
of the carrier, packing requirements, labelling, delivery documentation and information.
The delivery to the user is always via the regional distribution centres, which are also
audited.
Three different delivering procedures have to be taken into consideration:
● Delivery of the IC dedicated software components (IC dedicated SW, guidance) from the
TOE Manufacturer to the IC Embedded Software Developer.
● Delivery of the IC Embedded Software (ROM / Flash data, initialisation and
prepersonalization data, Bundle Business package) from the IC Embedded Software
Developer to the TOE Manufacturer.
● Delivery of the final TOE from the TOE Manufacturer to the Composite Product
Manufacturer. After phase 3 the TOE is delivered in form of wafers or sawn wafers, after
phase 4 in form of modules.
The individual TOE hardware is uniquely identified by its identification data. Each individual
TOE can be traced unambiguously and thus assigned to the entire development and
production process.
Furthermore, the chip identification data is accessible via the Generic Chip Identification
Mode (GCIM). The Generic Chip Identification Mode (GCIM) can be activated after power-
on with a dedicated signalling sequence and is also accessible by the user software. This
GCIM outputs a variety of unique identification information. Additionally the customer can
identify the present configuration by reading the relevant data in special memory area (see
[14], section 9.2.1). The firmware part of the TOE is also identified via the GCIM. The
firmware identifier represents the firmware parts RMS, BOS, FL, Mifare and patch version
(if existing). The RSA (optional), EC (optional), the Mifare-compatible Interface Libraries
(Card Management and Reader Mode) (optional), Toolbox (optional), Base Library
(optional), and SCL (optional), as separate software parts of the TOE, are as well identified
by their unique version numbers. Additionally, the user can also identify these versions by
a defined procedure. A mapping of these additional identification values to the version
numbers is provided in [6] chapter 10.
15 / 42
Certification Report BSI-DSZ-CC-0946-V3-2017
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 allow detection of
modifications after the delivery.
The TOE can be delivered in various configurations, achieved by means of blocking and
depending on the customer order. All product derivates of this TOE, including all
configuration possibilities differentiated by the GCIM (Generic Chip Identification Mode)
data and the configuration information output, are manufactured by Infineon Technologies
AG. New configurations can occur at any time depending on the user blocking or by
different configurations applied by the manufacturer. In any case the user is able to clearly
identify the TOE hardware, its configuration and proof the validity of the certificate
independently, meaning without involving the manufacturer. The various blocking options,
as well as the means used for the blocking, are done during the manufacturing process or
at user premises. Entirely all means of blocking and the, for the blocking involved firmware
respectively software parts, used at Infineon Technologies AG and/or the user premises,
are subject of the evaluation. All resulting configurations of a TOE derivative are subject of
the certificate. All resulting configurations are either at the predefined limits or within the
predefined configuration ranges. For more information about blocking, please compare
chapter 8.
3. Security Policy
The Security Policy is expressed by the 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 will implement a symmetric cryptographic block cipher algorithms (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 random number generation of appropriate
quality.
The SCL uses the symmetric cryptographic co-processor (SCP) of the hardware to provide
the user with a software interface to the DES and AES calculations and adds
countermeasures to assorted functions, protecting 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.
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
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
16 / 42
BSI-DSZ-CC-0946-V3-2017 Certification Report
● 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 chapter
7 and 8 of the Security Target [6] and [9].
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:
The ST only includes two security objectives 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 ([13], [15]), the TOE
application notes ([12]), other guidance documents ([14], [18], [16], [19]) and findings of
the TOE evaluation report are implemented. As all these documents 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 [12].
The ST only includes one security objective for the operational environment (for the
Composite Product Manufacturer), the objective OE.Process-Sec-IC.
● OE.Process-Sec-IC states that security procedures are used after delivery of the TOE by
the TOE Manufacturer up to delivery to the end-consumer to maintain confidentiality and
integrity of the TOE and of its manufacturing and test data (to prevent any possible copy,
modification, retention, theft or unauthorised use). This means that the phases after TOE
delivery are assumed to be protected appropriately.
The Composite Product Manufacturer therefore has to be informed only about the general
requirement resulting from OE.Process-Sec-IC. The Composite Product Manufacturer is
informed about these requirements resulting from OE.Process-Sec-IC in [18].
5. Architectural Information
The TOE is an integrated circuit (IC) providing a platform to a smart card operating system
and smart card application software. A top level block diagram and a list of subsystems
can be found within the TOE description of the Security Target Lite [9], chapter 2.1.
The TOE implements a dedicated security 32-bit RISC CPU designed on the basis of the
ARMv7_M architecture. The core system is then composed by the 32-bit CPU as a variant
of the ARM® SecurCore™ SC300™, the Cache system, the Memory Protection Unit and
the Memory Encryption/Decryption Unit. The TOE implements a full 32-bit addressing with
up to 4 GByte linear addressable memory space, a simple scalable memory management
concept and a scalable stack size. The TOE embeds its own ROM, RAM and Non Volatile
Memory, protected by the Infineon’s SOLID FLASH™ NVM1 memory system also called
NVM in the following description.
17 / 42
Certification Report BSI-DSZ-CC-0946-V3-2017
Two co-processors for cryptographic operations are implemented on the TOE. The
Crypto2304T for calculation of asymmetric algorithms like RSA and Elliptic Curve (EC) and
the Symmetric Cryptographic Processor (SCP) for dual-key or triple-key triple-DES and
AES calculations. These co-processors are especially designed for smart card applications
with respect to the security and power consumption. The SCP module computes the
complete DES algorithm within a few clock cycles and is especially designed to counter
attacks like DPA, EMA and DFA. The Crypto2304T module provides basic functions for the
implementation of RSA and EC cryptographic libraries.
The BOS (Boot Software) and the RMS (Resource Management System) compose the
TOE firmware stored in the ROM and the patches hereof in the NVM. All mandatory
functions for start-up and internal testing are protected by a dedicated hardware firewall.
Additionally two levels are provided, the privileged level and the user level, both are
protected by a hardwired Memory Protection Unit (MPU) setting.
The RMS is accessible in privileged level only. The FL (Flash Loader) and the Mifare-
compatible software compose the TOE software stored in the NVM. The FL allows
downloading of User Software into the NVM during the manufacturing process and can be
completely deactivated.
The Symmetric cryptographic library (SCL), delivered as object code (optional), provides a
high level interface to the DES/TDES and AES of the hardware component SCP.
As well as the RSA and EC libraries, delivered as object code (also optional), which
provide a high level interface to EC implemented on the hardware component
Crypto@2304T.
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 covered all security functionalities and all security mechanisms as
identified in the functional specification.
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. Independent tests were performed, in order to supplement, augment and to verify the
tests performed by the developer. For the developer tests repeated by the evaluators,
18 / 42
BSI-DSZ-CC-0946-V3-2017 Certification Report
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 confirmed 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
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:
●Smartcard IC M5072 G11 (Tainan/Taiwan).
This TOE is represented by various configurations called products, which are all derived
from the equal hardware design M5072. The same mask is used to produce different
products of the TOE. The first metal mask (called the M1 mask) contains the specific
information to identify the TOE.
The M5072 product offers different configuration options, which a customer can choose.
The mechanism to choose a configuration can be done by the following methods:
●by product selection or dialog-based in Tools,
●via Bill-per-Use (BPU) and Flash Loader (FL).
The degree of freedom for configuring the TOE is predefined by Infineon Technologies AG.
The list of predefined TOE configurations is given, as an example in the Securiy Target [6]
and [9] in Table 4 and in the Hardware Reference Manual [13], section 18.
All these possible TOE configurations equal and/or within the specified ranges are covered
by the certificate. Beside fix TOE configurations, which can be ordered as usual, this TOE
implements optionally the so called Bill-Per-Use (BPU) ability. This solution enables the
customer to tailor the product on his own to the required configuration by blocking parts of
the chip on demand into the final configuration at his own premises, without further
delivery or involving support by Infineon Technology AG. Customers, who are intended to
use this feature receiving the TOE in a predefined configuration including the Flash Loader
software, enhanced with the BPU blocking software. The blocking information is part of a
chip configuration area and can be modified by customers using specific APDUs. Once a
final blocking is done, further modifications are disabled. The BPU software part is only
present on the products which have been ordered with the BPU option. In all other cases
this software is not present on the product. For more details please refer to the Security
Target [6] and [9], chapters 2.2.7 and 2.2.8.
Depending on the blocking configuration, a M5072 product can have different user
available configurations listed in Table 4 of the Security Target [6] and [9].

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 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,
● Guidance, Smartcard Evaluation,
(see [4], AIS 25, AIS 26, AIS 31).
For RNG assessment the scheme interpretations AIS 31 was used (see [4]).
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 5 package including the class ASE as defined in the CC (see
also part C of this report),
● The components ALC_DVS.2 and AVA_VAN.5 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-0946-V2-2015, re-use of specific
evaluation tasks was possible. The focus of this re-evaluation was on inclusion of the
asymmetric and symmetric crypto libs, as well as respective guidance documentation
changes.
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 extended
● for the Assurance: Common Criteria Part 3 conformant
EAL 5 augmented by ALC_DVS.2 and AVA_VAN.5
For specific evaluation results regarding the development and production environment see
annex B in part D of this report.
20 / 42
BSI-DSZ-CC-0946-V3-2017 Certification 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).
An overview over the provided cryptographic functionalities is given in the Security Target
[6] (table 17) and [9] in table 16. Any Cryptographic Functionality therein, that is marked
with with 'no' in the dedicated column 'Security Level above 100 Bits', achieves a security
level of lower than 100 Bits (in general context).
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.
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 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] - [17] and [19] 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 [18] have to be considered.
In addition the following hint resulting from the evaluation of the ALC evaluation aspect has
to be considered:
21 / 42
Certification Report BSI-DSZ-CC-0946-V3-2017
● 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.”

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
32 / 42
BSI-DSZ-CC-0946-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.
33 / 42
Certification Report BSI-DSZ-CC-0946-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.”
