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. 1 Act on the Federal Office for Information Security (BSI-Gesetz - BSIG) of 14 August 2009, Bundesgesetzblatt I p. 2821 5 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 Contents A.

Certification 1. Specifications of the Certification Procedure The certification body conducts the procedure according to the criteria laid down in the following: ● Act on the Federal Office for Information Security2 ● BSI Certification and Approval Ordinance3 ● BSI Schedule of Costs4 ● Special decrees issued by the Bundesministerium des Innern (Federal Ministry of the Interior) ● DIN EN ISO/IEC 17065 standard ● BSI certification: Scheme documentation describing the certification process (CC- Produkte) [3] ● BSI certification: Scheme documentation on requirements for the Evaluation Facility, its approval and licencing process (CC-Stellen) [3] ● Common Criteria for IT Security Evaluation (CC), Version 3.15 [1] also published as ISO/IEC 15408. ● Common Methodology for IT Security Evaluation (CEM), Version 3.1 [2] also published as ISO/IEC 18045. ● BSI certification: Application Notes and Interpretation of the Scheme (AIS) [4] 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. 2 Act on the Federal Office for Information Security (BSI-Gesetz - BSIG) of 14 August 2009, Bundesgesetzblatt I p. 2821 3 Ordinance on the Procedure for Issuance of Security Certificates and approval by the Federal Office for Information Security (BSI-Zertifizierungs- und -Anerkennungsverordnung - BSIZertV) of 17 December 2014, Bundesgesetzblatt 2014, part I, no. 61, p. 2231 4 Schedule of Cost for Official Procedures of the Bundesamt für Sicherheit in der Informationstechnik (BSI-Kostenverordnung, BSI-KostV) of 03 March 2005, Bundesgesetzblatt I p. 519 5 Proclamation of the Bundesministerium des Innern of 12 February 2007 in the Bundesanzeiger dated 23 February 2007, p. 3730 7 / 42 Certification Report BSI-DSZ-CC-0964-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_INT.2, ADV_TDS.4, ALC_CMS.5, ALC_TAT.2, ATE_DPT.3 and AVA_VAN.5 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. 8 / 42 BSI-DSZ-CC-0964-V3-2017 Certification Report 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 Security Controller M7794 A12 / G12 with optional RSA2048/4096 v1.02.013 or v2.00.002, EC v1.02.013 or v2.00.002 and Toolbox v1.02.013 or v2.00.002 libraries and with specific IC-dedicated software has undergone the certification procedure at BSI. This is a re-certification based on BSI-DSZ-CC-0964-V2- 2017. Specific results from the evaluation process BSI-DSZ-CC-0964-V2-2017 were re- used. The evaluation of the product Infineon Technologies Security Controller M7794 A12 / G12 with optional RSA2048/4096 v1.02.013 or v2.00.002, EC v1.02.013 or v2.00.002 and Toolbox v1.02.013 or v2.00.002 libraries and with specific IC-dedicated software was conducted by TÜV Informationstechnik GmbH. The evaluation was completed on 5 September 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 8 September 2017 is valid until 7 September 2022. Validity can be re-newed by re-certification. 6 Information Technology Security Evaluation Facility 9 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 The owner of the certificate is obliged: 1. when advertising the certificate or the fact of the product's certification, to refer to the Certification Report as well as to provide the Certification Report, the Security Target and user guidance documentation mentioned herein to any customer of the product for the application and usage of the certified product, 2. to inform the Certification Body at BSI immediately about vulnerabilities of the product that have been identified by the developer or any third party after issuance of the certificate, 3. to inform the Certification Body at BSI immediately in the case that security relevant changes in the evaluated life cycle, e.g. related to development and production sites or processes, occur, or the confidentiality of documentation and information related to the Target of Evaluation (TOE) or resulting from the evaluation and certification procedure where the certification of the product has assumed this confidentiality being maintained, is not given any longer. In particular, prior to the dissemination of confidential documentation and information related to the TOE or resulting from the evaluation and certification procedure that do not belong to the deliverables according to the Certification Report part B, or for those where no dissemination rules have been agreed on, to third parties, the Certification Body at BSI has to be informed, 4. to inform the product customer (together with BSI) in case of cryptographic weaknesses in order to enable the customers to decide, based on their risk management decisions, whether to further use respective cryptographic mechanisms.. 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.

Certification Results The following results represent a summary of ● the Security Target of the sponsor for the Target of Evaluation, ● the relevant evaluation results from the evaluation facility, and ● complementary notes and stipulations of the certification body. 11 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 1. Executive Summary The Target of Evaluation (TOE) is the Infineon Technologies Security Controller M7794 A12 / G12 with optional RSA2048/4096 v1.02.013 or v2.00.002, EC v1.02.013 or v2.00.002 and Toolbox v1.02.013 or v2.00.002 libraries and with specific IC-dedicated software. The major components of the core system are the CPU, the MMU (Memory Management Unit) and MED (Memory Encryption/Decryption Unit). The coprocessor block contains the processors for RSA/EC and 3DES/AES processing, while the peripheral block contains the random number generation and the external interfaces service. The peripheral block also contains the timers and a watchdog. All data of the memory block is encrypted, RAM and ROM are equipped with an error detection code and the SOLID FLASH™ memory is equipped with an error correction code (ECC). The Security modules manage the alarms. Alarms may be triggered when the environmental conditions are outside the specified operational range. The block diagram of the TOE is shown in [6] and [9], Figure 1. The TOE comprises as one part the hardware of the smart card security controller in various configurations. The TOE is able to communicate using either its contact based or contactless interface. The implemented dual interface provides the flexibility to use different communication protocols: e.g. ISO 7816, ISO 14443 Type A and Type B, ISO/IEC 18092 passive, Mifare compatible Interface or the Digital Contactless Bridge mode (DCLB) can be chosen and configured. The DCLB mode enables the use of an external analogue interface or near field communication (NFC) modem via the ISO-pads. Those external analogue modems are typically deemed for applications running in mobile devices and are not part of this TOE. Whether the DCLB option is available or not is a configuration applied in TOE production which cannot be changed afterwards. 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 according to the life cycle model from [8]. 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 Smartcard Embedded Software itself is not part of the TOE. The TOE is represented by various configurations called products.The module design, layout and footprint, of all products are identical. However, minor differences between one metal mask allows the TOE to connect to different types of antennas (not part of the TOE). The metal masks differ in their input capacities of the RFI peripheral. The degree of freedom for configuring the TOE is predefined by Infineon Technologies AG. For more details please refer to the Security Target [9], chapter 2.2.7. The symmetric coprocessor (SCP) combines both AES and triple DES with dual-key or triple-key hardware acceleration. The asymmetric crypto coprocessor, called Crypto2304T in the following, supports RSA-2048 bit (4096-bit with CRT) and Elliptic Curve (EC) cryptography. The software part of the TOE consists of the cryptographic libraries RSA and EC and the supporting Toolbox and Base Libraries. If RSA or EC or Toolbox is part of the shipment, the Base Library is automatically included. The Base Library provides the low level interface to the asymmetric cryptographic coprocessor for the cryptographic libraries and has no user interface. It does not support any security relevant policy or function. 12 / 42 BSI-DSZ-CC-0964-V3-2017 Certification Report The cryptographic libraries RSA and EC and the Toolbox library are delivery options. If one of the libraries RSA, EC or Toolbox is delivered, the Base Library is automatically part of it. Therefore the user may choose a free combination of these libraries. In the case of deselecting one or several of these libraries the TOE does not provide the corresponding functionality for Additional Specific Security Functionality Rivest-Shamir-Adleman Cryptography (RSA) and/or Elliptic Curve Cryptography (EC). The Toolbox and Base Library are no cryptographic libraries and provide no additional specific security functionality. The RSA library is used to provide a high-level interface to RSA (Rivest, Shamir, Adleman) cryptography implemented on the hardware component Crypto2304T and includes countermeasures against SPA, DPA and DFA attacks. The hardware Crypto2304T unit provides the basic long number calculations (add, subtract, multiply, square with 1100 bit numbers) with high performance. The RSA library is delivered as object code. The RSA library can perform RSA operations from 512 to 4096 bits. The key lengths below 1024 bits are not included in the certificate. The EC library is used to provide a high-level interface to Elliptic Curve cryptography implemented on the hardware component Crypto2304T and includes countermeasures against SPA, DPA and DFA attacks. The routines are used for ECDSA signature generation, ECDSA signature verification, ECDSA key generation and Elliptic Curve Diffie- Hellman key agreement. The EC library is delivered as object code. The certification covers the standard NIST and Brainpool Elliptic Curves with different key lengths. For more details please refer to the Security Target [6] and Security Target Lite [9], chapter 1.2. This TOE is equipped with Flash Loader software (FL). It supports download of user software or parts of it to SOLID FLASH™. After completion of the download the Flash Loader can be deactivated permanently by the user. For more details please refer to the Security Target [6] and [9], chapter 2.2.2. 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 AVA_VAN.5 and ALC_DVS.2. 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 Functionality and features 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. SF_PS Protection against Snooping: The TOE uses various means to protect from snooping of memories and busses and prevents single stepping. 13 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 TOE Security Functionality Functionality and features SF_PMA Protection against Modifying Attacks: This TOE implements protection against modifying attacks of memories, alarm lines and sensors. SF_PLA Protection against Logical Attacks: Memory access of the TOE is controlled by a Memory Management Unit (MMU), which implements different privileged levels. The MMU decides, whether access to a physical memory location is allowed based on the access rights of the privilege levels. SF_CS Cryptographic Support: The TOE is equipped with an asymmetric and a symmetric hardware accelerator and also software modules to support several asymmetric cryptographic operations. It further provides random numbers to meet class PTG.2 of AIS31. Table 1: TOE Security Functionalities For more details please refer to the Security Target [6] and [9], chapter 7. 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], chapter 4.1 and 4.2. 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. 2. Identification of the TOE The Target of Evaluation (TOE) is called: Infineon Technologies Security Controller M7794 A12 / G12 with optional RSA2048/4096 v1.02.013 or v2.00.002, EC v1.02.013 or v2.00.002 and Toolbox v1.02.013 or v2.00.002 libraries and with specific IC-dedicated software.

The individual TOE hardware is uniquely identified by its serial number. 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. 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 amongst others a chip identifier byte, design step, firmware identifier, metal configuration identifier, temperature range and system frequency. Additionally, dedicated RMS functions allow a customer to extract the present hardware configuration. The hardware part of the TOE (in general) is identified by M7793 A12 and G12. By the above mentioned GCIM chip identification data, the IC Embedded Software Developer can clearly identify a product in question by the ChipIdent function and the user guidance, whereas additional RMS functions provides the complete chip configuration. Thereby, the exact and clear identification of any product with its exact configuration of this TOE is given. The Chip Type is listed in [13], table 1-8 and [18], chapter 4.4. The firmware part of the TOE is also identified via the GCIM. The RSA (optional), EC (optional), Toolbox (optional), and Base Library (optional) as separate software parts of the TOE are 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 [6] and [9], section 10. 3. Security Policy The Security Policy is expressed by the set of Security Functional Requirements and implemented by the TOE. 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 algorithm (Triple-DES and AES) to ensure the confidentiality of plain text data 16 / 42 BSI-DSZ-CC-0964-V3-2017 Certification Report by encryption and to support secure authentication protocols and it will provide a True Random Number Generator (TRNG). The RSA Library is used to provide a high level interface to RSA (Rivest, Shamir, Adleman) cryptography implemented on the hardware component Crypto2304T 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 Crypto2304T 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 ● maintain the integrity, the correct operation and the confidentiality of security functionalities (security mechanisms and associated functions) provided by the TOE. 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: protection during packaging, finishing and personalization, usage of hardware platform and treatment of user data. The augmented organizational security policy P.Add-Functions, derived from the additional security functionality of the cryptographic libraries, the augmented assumption A.Key-Function, related to the usage of key-depending functions, and the threat of memory access violation T.Mem-Access, due to specific TOE memory access control functionality, have been added. Details can be found in the Security Target [6] and Security Target Lite [9], chapter 4.3. 5. Architectural Information The TOE is an integrated circuits (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 [7], chapter 2.1. The major components of the core system are the CPU, the MMU (Memory Management Unit) and MED (Memory Encryption/Decryption Unit). The TOE implements a 16-MByte linear addressable memory space, a simple scaleable Memory Management concept and a scaleable stack size. The flexible memory concept consists of ROM and SOLID FLASH™. The symmetric coprocessor (SCP) combines both AES and triple DES with dual-key or triple-key hardware acceleration. The asymmetric crypto coprocessor, called Crypto2304T in the following, supports RSA-2048 bit (4096-bit with CRT) and Elliptic Curve (EC) cryptography. 17 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 The software part of the TOE consists of the cryptographic libraries RSA and EC, the Toolbox and Base library. If RSA or EC or Toolbox is part of the shipment, the Base Library is automatically included. The Base Library provides the low level interface to the asymmetric cryptographic coprocessor and has no user available interface. Part of the evaluation are the RSA straight operations with key lengths from 1024 bits to 2048 bits, and the RSA CRT operations with key lengths of 1024 bits to 4096 bits. Note that key lengths below 1024 bits are not included in the certificate. The Flash Loader is a firmware located in the user-ROM and allowing downloading the user software or parts of it to the NVM memory. The download is only possible after successful authentication. After completion of the download the Flash Loader can be permanently deactivated by the user. For more details please refer to the Security Target Lite [6] and [9], chapter 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 (and partly by the evaluator) were divided into five categories: ● Simulation tests (design verification): In the course of the development of the TOE simulation tests are carried out. These simulation tests yield CRC sums, which are used in the further testing. ● Qualification tests: For each mask version a qualification test is performed. Via the results of these tests a qualification report is generated. The positive result of the qualification is one part of the necessary testing results documented with the qualification report. The qualification report is completed after the verification testing (see below) and the security evaluation (see below) are performed successfully. The tests performed and their results are listed in the qualification report. The results of the tests are the basis on which it is decided, whether the TOE is released to production. ● Verification Tests: With these tests in user mode the functionality of the end user environment is checked. ● Security Evaluation Tests: In the context of security evaluation testing the security mechanisms is tested again in the user mode only focusing on security. Here is not only verified that the security functionality is working as this was already tested on every single TOE during production, but also it is tested how well the security functionality is working and the effectiveness is calculated. This step is necessary as the mechanisms work together and that must be evaluated in the user mode. 18 / 42 BSI-DSZ-CC-0964-V3-2017 Certification Report ● Production Tests: Before delivery on every chip production tests are performed. These tests use the CRC checksums attained by the simulation tests. The aim of these tests is to check whether each chip is functioning correctly. The tests cover 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 developers site. They performed independent tests to supplement, augment and to verify the tests performed by the developer. The tests of the developer were repeated by sampling, by repetition of complete regression tests and by software routines developed by the evaluators and computed on samples with an evaluation operating system. 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 showed 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 the underlying mechanisms of security functionalities using bespoke equipment and expert know how. 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 M7794 A12 (produced in Dresden), ● Smartcard IC M7794 G12 (produced in Tainan). Depending on the blocking configuration a M7794 A12 and G12 product can have e.g. different user available memory sizes and can come with or without individual accessible cryptographic co-processor. More information are given in [6] and [9], section 2.2.7. The entire configuration is done during the manufacturing process of the TOE according to the choice of the user or by Bill Per Use (BPU). BPU allows a customer to block chips on demand at the customer´s premises. Customers, who intend to use this feature receive the TOEs in a predefined configuration. The blocking information is part of a chip configuration area. Dedicated blocking information can be modified by customers using specific APDUs. Once final blocking is done, further modifications are disabled. The dedicated RMS functions allow a customer to extract the present hardware configuration and the original Chip Identifier Byte, which was valid before blocking. The blocking mechanism is also part of the evaluation. For more details please refer to the Security Target [6] and [9], chapter 2.2.7 and 2.2.8. 19 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 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 (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 5 package including the class ASE as defined in the CC (see also part C of this report) ● The components AVA_VAN.5 and 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-0964-V2-2017, re-use of specific evaluation tasks was possible. The focus of this re-evaluation was on 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 AVA_VAN.5 and ALC_DVS.2 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. 20 / 42 BSI-DSZ-CC-0964-V3-2017 Certification Report 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 claimed cryptopgraphic functionalities is given in the Security Target [6] and [9], section 7.1.4. Any Cryptographic Functionality therein, that is marked in column 'Security Level above 100 Bits' with 'no', 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] 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. 21 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 ● 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.

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.” 29 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 CC Part 3: Class APE: Protection Profile evaluation (chapter 10) “Evaluating a PP is required to demonstrate that the PP is sound and internally consistent, and, if the PP is based on one or more other PPs or on packages, that the PP is a correct instantiation of these PPs and packages.

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-0964-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-0964-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.” 34 / 42 BSI-DSZ-CC-0964-V3-2017 Certification Report Assurance Class Assurance Family Assurance Components by Evaluation Assurance Level EAL 1 EAL 2 EAL 3 EAL 4 EAL 5 EAL 6 EAL 7 Development ADV_ARC 1 1 1 1 1 1 ADV_FSP 1 2 3 4 5 5 6 ADV_IMP 1 1 2 2 ADV_INT 2 3 3 ADV_SPM 1 1 ADV_TDS 1 2 3 4 5 6 Guidance Documents AGD_OPE 1 1 1 1 1 1 1 AGD_PRE 1 1 1 1 1 1 1 Life cycle Support ALC_CMC 1 2 3 4 4 5 5 ALC_CMS 1 2 3 4 5 5 5 ALC_DEL 1 1 1 1 1 1 ALC_DVS 1 1 1 2 2 ALC_FLR ALC_LCD 1 1 1 1 2 ALC_TAT 1 2 3 3 Security Target Evaluation ASE_CCL 1 1 1 1 1 1 1 ASE_ECD 1 1 1 1 1 1 1 ASE_INT 1 1 1 1 1 1 1 ASE_OBJ 1 2 2 2 2 2 2 ASR_REQ 1 2 2 2 2 2 2 ASE_SPD 1 1 1 1 1 1 ASE_TSS 1 1 1 1 1 1 1 Tests ATE_COV 1 2 2 2 3 3 ATE_DPT 1 1 3 3 4 ATE_FUN 1 1 1 1 2 2 ATE_IND 1 2 2 2 2 2 3 Vulnerability assessment AVA_VAN 1 2 2 3 4 5 5 Table 6: Evaluation assurance level summary 35 / 42 Certification Report BSI-DSZ-CC-0964-V3-2017 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.” 36 / 42 BSI-DSZ-CC-0964-V3-2017 Certification Report D.
