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 ● BSI Schedule of Costs3 ● 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 3.14 [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 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 7 / 35 Certification Report BSI-DSZ-CC-0961-V3-2018 ● 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.sogisportal.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: 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 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+ ALC_FLR components. 4 Proclamation of the Bundesministerium des Innern of 12 February 2007 in the Bundesanzeiger dated 23 February 2007, p. 3730 8 / 35 BSI-DSZ-CC-0961-V3-2018 Certification Report 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 Infineon smart card IC (Security Controller) IFX_CCI_000007h, IFX_CCI_000009h, IFX_CCI_00000Ah, IFX_CCI_00000Bh, IFX_CCI_000016h, IFX_CCI_000017h, IFX_CCI_000018h, IFX_CCI_000023h, IFX_CCI_000024h design step G13 with optional libraries CIPURSE™ CL, RSA2048/4096, EC, Toolbox, HSL, SCL and with specific IC dedicated software has undergone the certification procedure at BSI. This is a re-certification based on BSI-DSZ-CC-0961-V2-2018. Specific results from the evaluation process BSI-DSZ-CC-0961-V2-2018 were re-used. Also, specific ALC related parts were re-used in the sense of AIS38 from BSI-DSZ-CC-1079. The evaluation of the product Infineon smart card IC (Security Controller) IFX_CCI_000007h, IFX_CCI_000009h, IFX_CCI_00000Ah, IFX_CCI_00000Bh, IFX_CCI_000016h, IFX_CCI_000017h, IFX_CCI_000018h, IFX_CCI_000023h, IFX_CCI_000024h design step G13 with optional libraries CIPURSE™ CL, RSA2048/4096, EC, Toolbox, HSL, SCL and with specific IC dedicated software was conducted by T-Systems International GmbH. The evaluation was completed on 20 September 2018. T-Systems International 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. 5 Information Technology Security Evaluation Facility 9 / 35 Certification Report BSI-DSZ-CC-0961-V3-2018 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 26 September 2018 is valid until 25 September 2023. 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, 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. 11 / 35 Certification Report BSI-DSZ-CC-0961-V3-2018 1. Executive Summary The TOE is named Infineon smart card IC (Security Controller) IFX_CCI_000007h, IFX_CCI_000009h, IFX_CCI_00000Ah, IFX_CCI_00000Bh, IFX_CCI_000016h, IFX_CCI_000017h, IFX_CCI_000018h, IFX_CCI_000023h, IFX_CCI_000024h design step G13 with optional libraries CIPURSE™ CL, RSA2048/4096, EC, Toolbox, HSL, SCL and with specific IC dedicated software and is an integrated circuit (IC) in 65nm technology, providing a platform for an operating system and application software used in smartcards but also in any other device or form factor requiring a high level of resistance against attackers. The Security Target [6] and [9] 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. They are selected from Common Criteria Part 2 and some of them are newly defined. Thus the TOE is CC Part 2 extended. The TOE Security Functional Requirements are implemented by the following TOE Security Functionality: TOE Security Functionality Addressed issue SF_DPM Device Phase Management SF_PS Protection against Snooping SF_PMA Protection against Modification Attacks SF_PLA Protection against Logical Attacks SF_CS Cryptographic Support Table 1: TOE Security Functionalities For more details please refer to the Security Target [6] and [9], chapter 7.4 (Security Requirements Rationale). 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. This certification covers the configurations of the TOE as outlined in chapter 8. Within the Security Target [6] and [9], references to, and aspects of, GBIC (German Banking Industry Committee) are given. Unless Common Criteria relevant refinements are made to CC contents, these GBIC topics are to be regarded as parallel and independent of the CC certification. 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). 12 / 35 BSI-DSZ-CC-0961-V3-2018 Certification Report 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.

Furthermore, 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. Three different delivery 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. 15 / 35 Certification Report BSI-DSZ-CC-0961-V3-2018 ● Delivery of the IC Embedded Software (ROM / Flash data, initialisation and pre- personalisation data) 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 (with or without inlay antenna). Respective distribution centers are listed in Appendix B (see below). The individual TOE hardware is uniquely identified by its identification data. The identification data contains the CCI (Common Criteria identifier), lot number, the wafer number and the coordinates of the chip on the wafer. Each individual TOE can therefore be traced unambiguously and thus assigned to the entire development and production process. The hardware part of the TOE is identified by IFX_CCI_000007h, IFX_CCI_000009h, IFX_CCI_00000Ah, IFX_CCI_00000Bh, IFX_CCI_000016h, IFX_CCI_000017h, IFX_CCI_000018h, IFX_CCI_000023h and IFX_CCI_000024h design step G13. Another characteristic of the TOE are the chip identification data. These chip identification data is accessible via the Generic Chip Identification Mode (GCIM). At TOE start-up the so called GCIM can be chosen by applying special signalling in contactless or contact based communication and the TOE outputs then the generic chip identification data. This data contain the firmware identifier accompanied with the certification identifier, the design step and even more tracking information. In combination with [12] (section 6.5) the user can identify the data, interpret it and retrieve the TOE versioning information. This information includes also the required mapping of firmware identifier and certification identifier. The optional software libraries can be identified by calculating a hash value (e.g. SHA-256) over the delivered lib-files (.lib) and comparing the calculated vales to the values stated in Security Target [6] and [9], section 11. Please also note, that as the TOE is under control of the user software, the TOE Manufacturer can only guarantee the integrity up to the delivery procedure. It is in the responsibility of the Composite Product Manufacturer to include mechanisms in the implemented software (developed by the IC Embedded Software Developer) which allows detection of modifications after the delivery. 3. Security Policy The Security Policy is expressed by the set of Security Functional Requirements and implemented by the TOE. It provides basic security functionalities to be used by a smart card operating system and a smart card application, thus providing an overall smart card system security. Therefore, the TOE implements a symmetric cryptographic block cipher algorithm (Triple-DES and AES) to ensure the confidentiality of plain text data by encryption and to support implementations of secure authentication protocols. It furthermore provides a True Random Number Generator (TRNG), Hybrid Random Generator (HRNG), and Deterministic Random Number Generator (DRNG). 16 / 35 BSI-DSZ-CC-0961-V3-2018 Certification Report The RSA Library is used to provide a high level interface to RSA (Rivest, Shamir, Adleman) cryptography implemented on the core and on the hardware asymmetric coprocessor 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 core and on hardware asymmetric coprocessor 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. The TOE as well implements user manageable memory access control policy. The security policy of memory access control policy has been formally modelled. The formal model covers further security policies. 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. Regarding the operational environment of the TOE the security objectives OE.Resp-Appl (Treatment of User Data of the Composite TOE), and OE.Process-Sec-IC (Protection during composite product manufacturing), OE.Lim_Block_Loader (Limitation of capability and blocking the Loader), OE.TOE_Auth (External entities authenticating of the TOE) and OE.Loader_Usage (Secure communication and usage of the Loader) are relevant for the user in context of secure installation of the TOE and the secure preparation of the operational environment. All objectives are properly covered by user guidance. 5. Architectural Information The TOE is an integrated circuit (IC) providing a platform for an operating system and application software used in smartcards but also in any other device or form factor requiring a high level of resistance against attackers. A top level block diagram and a list of subsystems can be found within the TOE description of the Security Target [6] and [9], chapter 2.1. The TOE provides a real 16-bit CPU-architecture and is compatible to the Intel 80251 architecture. The major components of the core system are the two CPUs (Central Processing Units), the MMU (Memory Management Unit) and MED (Memory Encryption/Decryption Unit). The two CPUs control each other in order to detect faults and serve by this for data integrity. The TOE implements a linear addressable memory space for each privilege level and a simple scalable Memory Management concept. The flexible memory concept consists of ROM- and Flash-memory as part of the non volatile memory (NVM). There is 17 / 35 Certification Report BSI-DSZ-CC-0961-V3-2018 no user available on-chip ROM module. The user software and data are now located in a dedicated and protected part of the NVM. The two cryptographic co-processors serve the need of modern cryptography: The symmetric co-processor (SCP) combines both AES and Triple-DES with dual-key or triple- key hardware acceleration. The Asymmetric Crypto Co-processor is used for RSA and Elliptic Curve (EC) cryptography. The software part of the TOE consists of the cryptographic CIPURSETM , EC-, RSA- and symmetric cryptography libraries and the supporting Toolbox libraries. The Flash Loader is a firmware located in the ROM and enables the download of the user software or parts of it to the NVM. After completion of the download and before delivery the final user the Flash Loader shall be locked by the user. 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 can be divided into following categories: ● technology development tests as the earliest tests to check the technology against the specification and to get the technology parameters used in simulations of the circuitry (this testing is not strictly related to Security Functions), ● tests which are performed in a simulation environment for analogue and for digital simulations, ● regression tests which are performed for the IC Dedicated Test Software (optional software libraries) and for the IC Dedicated Support Software (BOS) on emulator versions of the TOE or within the simulation of chip in special hardware, or on final hardware and firmware, ● qualification tests to release the TOE to production: • used to determine the behaviour of the chip with respect to different operating conditions and varied process parameters (often also referred to as characterisation tests) • special verification tests for Security Functions which were done with samples of the TOE (referred also as developers security evaluation) and which include also layout tests by automatic means and optical control, in order to verify statements concerning the layout; ● functional production tests, which are done for every chip to check its correct functionality as a last step of the production process (phase 3 or phase 4 depending on the TOE delivery form). The developer tests cover all Security Functions and all security mechanisms as identified in the functional specification, and in the high and low level designs. 18 / 35 BSI-DSZ-CC-0961-V3-2018 Certification Report 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 sites. They performed independent tests to supplement, augment and to verify the tests performed by the developer by sampling or by complete repetition of regression tests especially for the software. Besides repeating exactly the developer’s tests, test parameters and test equipment are varied and additional analysis was done. 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 developer has tested the TOE. In cases that different configurations were tested, the evaluators assessed the validity of test results for the TOE. The evaluators supplied evidence that the actual version of the TOE provides the Security Functions as specified by the developer. The test results confirm the correct implementation of the TOE Security Functions. For penetration testing the evaluators took all Security Functions into consideration. Intensive penetration testing was planed based on the analysis results and performed for the underlying mechanisms of Security Functions 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 (i.e. DPA/SPA testing). The evaluators have tested the TOE. In cases that different configurations were tested, the evaluators assessed the validity of test results for the TOE. 8. Evaluated Configuration The evaluated derivate of the TOE is IFX_CCI_000007h (with options/other identifiers, see below), G13 with firmware and optional software libraries (CCL, RSA2048 2k and 4k, EC, Toolbox, HSL, SCL) with revisions stated in section 2. The flash loader (part of FW) was enabled on evaluated derivative. The BPU feature was not used. All hardware modules and all interfaces incl. options were activated and the ranges of available memories was not limited (i.e. maximum size was available). The system frequency was set at its maximum value. The derivative was manufactured in wafer fab Tainan, Taiwan. An extensive overview over all possible configuration options is given in the Security Target [6] and [9] in table 4. The evaluation results, also including results of tests performed by the developer, are valid for all hardware derivates of the configuration IFX_CCI_000007h, G13 (including all further identifiers 000009h, 00000Ah, 00000Bh, 000016h, 000017h, 000018h, 000023h, 000024h in design step G13). All identifiers represent the equal hardware platform but name differences in configurations or market segments. Configuration differences are achieved by blocking only. The firmware and optional software libraries (RSA2048 2k and 4k, EC, Toolbox, HSL, SCL were examined in those revisions, which are stated in table 2 (above). The evaluation results are valid for all configurations and blocking options of the hardware stated in table 4 of the Security Target [6] and [9]. Depending on configuration, blocking option and on selection of optional software libraries, some of the services might be unavailable to the user. The unavailable services have no security impact on the TOE. The user must ensure a working configuration, e.g. the RAM size shall be selected to fulfill the minimum requirement of RSA library, if it was also selected as an option. The evaluation 19 / 35 Certification Report BSI-DSZ-CC-0961-V3-2018 results apply to all configurations of Flash Loader, BPU and PIN-Letter as stated in table 3 of the Security Target [6] and [9]. The evaluation results cannot be extended to further versions/derivates of the TOE and/or other production sites without any extra investigations. 9. Results of the Evaluation 9.1.

For RNG assessment the scheme interpretations AIS 31 was used (see [4]). The assurance refinements outlined in the Security Target were followed in the course of the evaluation of the TOE. Please note that those parts, which are to be read in the GBIC context, are solely relevant in the GBIC context and not in the CC context (hence for CC these are out of scope). 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), 21 / 35 Certification Report BSI-DSZ-CC-0961-V3-2018 ● The components ALC_FLR.1 augmented for this TOE evaluation. This is a re-certification based on BSI-DSZ-CC-0961-V2-2018. 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. 9.2. Results of cryptographic assessment The strength of the cryptographic algorithms was not rated in the course of this certification procedure (see BSIG Section 9, Para. 4, Clause 2). But cryptographic functionalities with a security level of lower than 100 bits can no longer be regarded as secure without considering the application context. Therefore, for these functionalities it shall be checked whether the related crypto operations are appropriate for the intended system. Some further hints and guidelines can be derived from the 'Technische Richtlinie BSI TR-02102' (https://www.bsi.bund.de). The following table (which originates from the ITSEF-evaluated table in [21] and in this certification report is enhanced by the 100 bit column) provides 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 100 Bits' of the following table with 'no' achieves a security level of lower than 100 Bits (in general context) only.

The Flash Loader's cryptographic strength was also not assessed by BSI. However, the evaluation according to the TOE's Evaluation Assurance Level did not reveal any implementation weaknesses. Please note, that this holds true also for those algorithms, where no cryptographic 100-Bit- Level assessment was given. Consequently, the targeted Evaluation Assurance Level has been achieved for those functionalities as well.

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 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. In addition, all the instructions in the following user guidance documents shall be considered when using the TOE (see also section 13 below, bibliography): ● see documents [11] – [20]. The fulfilment of security objectives for the environment from the Security Target, [6] and [9] shall be ensured as well. 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]). 27 / 35 Certification Report BSI-DSZ-CC-0961-V3-2018 12. Definitions 12.1.
