Certification 1. 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. 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 Security1 ● BSI Certification and Approval Ordinance2 ● BMI Regulations on Ex-parte Costs 3 ● Special decrees issued by the Bundesministerium des Innern und für Heimat (Federal Ministry of the Interior and Community) ● 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 3.14 [1] also published as ISO/IEC 15408 1 Act on the Federal Office for Information Security (BSI-Gesetz - BSIG) of 14 August 2009, Bundesgesetzblatt I p. 2821 2 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 3 BMI Regulations on Ex-parte Costs - Besondere Gebührenverordnung des BMI für individuell zurechenbare öffentliche Leistungen in dessen Zuständigkeitsbereich (BMIBGebV), Abschnitt 7 (BSI- Gesetz) - dated 2 September 2019, Bundesgesetzblatt I p. 1365 6 / 26 BSI-DSZ-CC-0891-V7-2024 Certification Report ● 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] 3. 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. 3.1. European Recognition of 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. The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels EAL 1 to EAL 4. 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 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.sogis.eu. The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the terms of this agreement by the related bodies of the signatory nations. A disclaimer beneath the logo indicates the specific scope of recognition. This certificate is recognized under SOGIS-MRA for all assurance components selected. 3.2. 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 current list of signatory nations and approved certification schemes can be seen on the website: https://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 related bodies of the signatory nations. A disclaimer beneath the logo indicates the specific scope of recognition. This certificate is recognized according to the rules of CCRA-2014, i. e. up to and including CC part 3 EAL 2 and ALC_FLR components. 4 Proclamation of the Bundesministerium des Innern und für Heimat of 12 February 2007 in the Bundesanzeiger dated 23 February 2007, p. 3730 7 / 26 Certification Report BSI-DSZ-CC-0891-V7-2024 4. 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 M7892 Design Step G12, with specific IC dedicated firmware has undergone the certification procedure at BSI. This is a re-certification based on BSI-DSZ-CC-0891- V6-2021. Specific results from the evaluation process BSI-DSZ-CC-0891-V6-2021 were re-used. The evaluation of the product M7892 Design Step G12, with specific IC dedicated firmware was conducted by TÜV-IT GmbH. The evaluation was completed on 3 July 2024. TÜV-IT GmbH is an evaluation facility (ITSEF)5 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. 5. Validity of the Certification Result This Certification Report applies only to the version of the product as indicated. The confirmed assurance package is 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 components and assurance levels please refer to CC itself. Detailed references are listed in part C of this report. The Certificate issued confirms the assurance of the product claimed in the Security Target at the date of certification. As attack methods evolve over time, the resistance of the certified version of the product against new attack methods needs to be re-assessed. Therefore, the sponsor should apply for the certified product being monitored within the assurance continuity program of the BSI Certification Scheme (e.g. by a re-assessment or 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 would 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 July 2024 is valid until 7 July 2029. Validity can be re-newed by re-certification. 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, 5 Information Technology Security Evaluation Facility 8 / 26 BSI-DSZ-CC-0891-V7-2024 Certification Report 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. 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. 6.

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. 10 / 26 BSI-DSZ-CC-0891-V7-2024 Certification Report 1. Executive Summary The Target of Evaluation (TOE) is the Infineon Technologies AG Security Controller (Integrated Circuit IC), M7892 Design Step G12, with specific IC dedicated firmware with version 78.015.18.2. The TOE provides a real 16-bit CPU-architecture and is compatible to the Intel 80251 architecture. The major components of the core system are the two CPUs (Central Processing Units), the MMU (Memory Management Unit), and the MED (Memory Encryption/Decryption Unit). The dual interface controller is able to communicate using either the contact based or the contactless interface. The TOE consists of the hardware part and the firmware part. This TOE is intended to be used in smart cards for particularly security relevant applications and as a developing platform for smart card operating systems. The term Smartcard Embedded Software is used in the following for all operating systems and applications stored and executed on the TOE. The TOE is the platform for the Smartcard Embedded Software. The Security Target [6] is the basis for this certification. It is based on the certified Protection Profile Security IC Platform Protection Profile with Augmentation Packages Version 1.0, 13 January 2014, BSI-CC-PP-0084-2014 [8]. The TOE Security Assurance Requirements (SAR) are based entirely on the assurance components defined in Part 3 of the Common Criteria (see part C or [1], Part 3 for details). The TOE meets the assurance requirements of the Evaluation Assurance Level EAL 6 augmented by ALC_FLR.1. The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the Security Target [6] and [9], chapter 7.1. 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. SF_PS Protection against Snooping: The TOE uses various means to protect from snooping of memories and busses and prevents single stepping. 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: The memory access control of the TOE uses a memory management unit (MMU) to control the access to the available physical memory by using virtual memory addresses and to segregate the code and data to a privilege level model. The MMU controls the address permissions of up to seven privileged levels and gives the software the possibility to define different access rights. 11 / 26 Certification Report BSI-DSZ-CC-0891-V7-2024 TOE Security Functionality Addressed issue SF_CS Cryptographic Support: The TOE is equipped with a coprocessor supporting the DES and AES algorithms. Furthermore, the TOE is equipped with an AIS31 conformant TRNG that meets the functionality class PTG.2. 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 4.1.3. 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. 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: M7892 Design Step G12, with specific IC dedicated firmware The following table outlines the TOE deliverables: No Type Identifier Release Form of Delivery 1 HW M7892 Security Controller G12 Complete modules, with or without inlay mounting, in form of plain wafers or in any IC case (for example TSSOP28, VQFN32, VQFN40, CCS- modules, etc.) or in bare dies or whatever type of package or even in no package. 2 FW STS Self-Test Software (the IC Dedicated Test Software), RMS Resource Management System (the IC Dedicated Support Software), SAM (Service Algorithm Minimal), and NRG3 Software Interface Routines FW Identifier 78.015.18.2 Stored in reserved area of the ROM on the IC (patch in NVM). 12 / 26 BSI-DSZ-CC-0891-V7-2024 Certification Report No Type Identifier Release Form of Delivery 3 SW NVM image (including Embedded Software) The embedded software for the download into the SOLID FLASH™ NVM has to be provided to the TOE manufacturer.

The delivery documentation describes in a sufficient manner how the various procedures and technical measures provide for the detection of modifications and any discrepancies between the TOE respective parts of it send by the TOE Manufacturer and the version received by the Composite Product Manufacturer. Therefore, three different delivery procedures have to be taken into consideration: 1. Delivery of the IC dedicated software components (IC dedicated SW, guidance) from the TOE Manufacturer to the IC Embedded Software Developer. 2. Delivery of the IC Embedded Software (ROM / Flash data, initialisation and pre- personalisation data) from the IC Embedded Software Developer to the TOE Manufacturer. 3. 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 (with or without inlay antenna). Respective distribution centers are listed in Appendix B (see below). The hardware part of the TOE is identified as M7892 G12. The firmware of the TOE can be identified via the firmware identifier (see Table 2). 13 / 26 Certification Report BSI-DSZ-CC-0891-V7-2024 The user guidance as part of the TOE is identified in Table 2. Each user guidance document can be identified by the combination of its title, date, and version number. In the field, the Generic Chip Identification Mode (GCIM) allows the unique identification of each hardware via an individual chip identification number together with the design step. The GCIM further includes the firmware identifier and provides several detailed production parameters as well as the fabrication facility, tracking information, wafer number, production start (year and week) and lot. For clear differentiation between the mask sets, each of it has assigned an individual value in the data output of the GCIM. Thereby, the exact and clear identification of any product with its exact configuration of this TOE is given. The GCIM data is explained in the Hardware Reference Manual [11] section 7.11.3. Note that any hardware configuration comes with its own chip identifier byte. The chip identifier bytes are aimed to be used for the logistical processes but are available to the user as well. For the user’s clear TOE identification, the development code allowing reading out the present configuration of the TOE is sufficient. The GCIM is accessible by a dedicated power-on sequence and also by the customer software. 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 algorithm (TDES and AES) to ensure the confidentiality of plain text data by encryption and to support secure authentication protocols and it will provide a true random number generator (TRNG). 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 and TDES 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. Specific details concerning the above-mentioned security policies can be found in Chapter 7 and 8 of the Security Target [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: 14 / 26 BSI-DSZ-CC-0891-V7-2024 Certification Report The ST includes the following security objective for the IC Embedded Software Developer: OE.Resp-Appl. 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 [13]. The ST includes the following security objective for the operational environment, which is relevant for the Composite Product Manufacturer: 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). The Composite Product Manufacturer is informed about these requirements resulting from OE.Process-Sec-IC in [12]. Details can be found in the Security Target [6] and [9], chapter 5.2. 5. Architectural Information The TOE provides a real 16-bit CPU-architecture and is compatible to the Intel 80251 architecture. The major components of the core system are the two CPUs (Central Processing Units), the MMU (Memory Management Unit), and the MED (Memory Encryption/Decryption Unit). The dual interface controller is able to communicate using either the contact based or the contactless interface. The TOE consists of the hardware part and the firmware part. This TOE is intended to be used in smart cards for particularly security relevant applications and as a 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. 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. 15 / 26 Certification Report BSI-DSZ-CC-0891-V7-2024 The developer 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 by using the library of programs, tools and prepared chip samples delivered to the ITSEF or at the developer’s site. They performed independent tests to supplement, augment and to verify the tests performed by the developer. For the developer tests, repeated by the evaluators, other test parameters were used and the test equipment was varied. Security features of the TOE realised by specific design and layout measures were checked by the evaluators during layout inspections both in design data and on the final product. The evaluation has shown that the actual version of the TOE provides the security functionalities as specified by the developer. The test results confirm the correct implementation of the TOE security functionalities. For penetration testing the evaluators considered all security functionalities. 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 results of the penetration tests 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 M7892 G12 (TSMC Tainan). Hardware Configuration The hardware of the TOE can be ordered in various configurations, as described in the Security Target [6],[9] section 1.1/2.2.1. In regard to the security functionality of the TOE, the cryptographic coprocessors are of special importance. The Crypto2304T coprocessor provides functionalities for asymmetric cryptography and the SCP provides functionalities for symmetric cryptography. The TOE can be ordered with or without either the Crypto2304T or the SCP. If a TOE is ordered without a coprocessor, it is deactivated during the manufacturing process and cannot be reactivated by the user. Deselecting a cryptographic coprocessor has no impact on any other security policy of the TOE. It is exactly equivalent to the situation where the user decides just not to use the functionality. The Crypto2304T does not implement any security functionality. Firmware Packages There is only one firmware variant (firmware package) with the following firmware identifier available: ● 78.015.18.2. 16 / 26 BSI-DSZ-CC-0891-V7-2024 Certification Report 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) 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. As a result of the evaluation the verdict PASS is confirmed for the following assurance components: ● All components of the EAL 6 package including the class ASE as defined in the CC (see also part C of this report) ● The components ALC_FLR.1 augmented for this TOE evaluation. As the evaluation work performed for this certification procedure was carried out as a re- evaluation based on the certificate BSI-DSZ-CC-0891-V6-2021, re-use of specific evaluation tasks was possible. The focus of this re-evaluation was on the removal of all Cryptographic Libraries. The evaluation has confirmed: ● PP Conformance: Security IC Platform Protection Profile with Augmentation Packages Version 1.0, 13 January 2014, BSI-CC-PP-0084-2014 [8] ● for the Functionality: PP conformant plus product specific extensions Common Criteria Part 2 extended ● for the Assurance: Common Criteria Part 3 conformant EAL 6 augmented by ALC_FLR.1 For specific evaluation results regarding the development and production environment see annex B in part D of this report. The results of the evaluation are only applicable to the TOE as defined in chapter 2 and the configuration as outlined in chapter 8 above. 17 / 26 Certification Report BSI-DSZ-CC-0891-V7-2024 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 120 bits can no longer be regarded as secure without considering the application context. Therefore, for these functionalities it shall be checked whether the related crypto operations are appropriate for the intended system. Some further hints and guidelines can be derived from the 'Technische Richtlinie BSI TR-02102' (https://www.bsi.bund.de). The table in annex C of part D of this report gives an overview of the cryptographic functionalities inside the TOE to enforce the security policy and outlines its rating from cryptographic point of view. Any Cryptographic Functionality that is marked in column 'Security Level above 120 Bits' of the following table with 'no' achieves a security level of lower than 120 Bits (in general context) only. No. Cryptographic Mechanism Standard of Implementation Key Size in Bits Security Level above 120 Bits Cryptographic Primitive 1.

Obligations and Notes for the Usage of the TOE The documents as outlined in table 2 contain necessary information about the usage of the TOE and all security hints therein have to be considered. In addition all aspects of Assumptions, Threats and OSPs as outlined in the Security Target not covered by the TOE itself need to be fulfilled by the operational environment of the TOE. The customer or user of the product shall consider the results of the certification within his system risk management process. In order for the evolution of attack methods and techniques to be covered, he should define the period of time until a re-assessment of the TOE is required and thus requested from the sponsor of the certificate. The limited validity for the usage of cryptographic algorithms as outlined in chapter 9 has to be considered by the user and his system risk management process, too. 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]. At the point in time when evaluation and certification results are reused there might be an update of the document "ETR for composite evaluation" available. Therefore, the certified products list on the BSI website has to be checked for latest information on reassessments, recertifications or maintenance result available for the product. 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]). 12.
