The evaluation was performed as a re-evaluation process based on BSI-DSZ- CC-0269-2006. The TOE was re-evaluated because of a modification of the PSL software and including additional chip derivates (see below). The Security Target was updated. The smart card operating system and the application stored in the User ROM and in the NVM are not part of the TOE. The TOE provides a platform for applications requiring non-volatile data storage. The TOE is intended for use in a range of high security applications, including information integrity, access control, mobile telephone, as well as uses in electronic funds transfer and healthcare systems. The TOE is implemented in the 0,13 µm CMOS technology and manufactured in Infineons IC fabrication in Dresden, Germany, indicated by the production line indicator “2”. The hardware part of the TOE is the complete chip, composed of a dedicated microprocessor (CPU) with a virtual memory system (VMS), several different memories, security logic, a timer and an interrupt-controlled I/O interface. A Random Number Generator (RNG) is integrated on the chip. The memory comprises RAM, User ROM and NVM (Non Volatile Memory). The CPU accesses the memory via the integrated Memory Encryption and Decryption unit (MED). The access rights of the application to the memories can be controlled with the Virtual Memory System (VMS). Four modules for cryptographic operations are implemented on the TOE: (i) The coprocessor Crypto@1408BIT is used for calculation of asymmetric algorithms like RSA. In specific derivates this module is not available. (ii) The Data Encryption Standard (DES) algorithm is computed by the DES module. (iii) The Advanced Encryption Standard (AES) and (iv) Secure Hash Algorithm (SHA-1) are included as software modules in the Platform Support Layer (PSL) software. As IC Dedicated Software (refer to Protection Profile [8]), the firmware consists of two parts: The one is called Platform Support Layer (PSL). It provides a high level interface to the hardware devices like timers, UART (Universal Asynchronous Receiver Transmitter), Crypto@1408BIT, RNG, NVM, DES and to the cryptographic functions of AES, CRC (Cyclic Redundancy Check) and SHA-1. The PSL provides the user (operating system) with the functionality to load code and data to the memory areas of the TOE in a secured process. The PSL is stored in ROM and NVM of the TOE. As the PSL provides the TOE security functions interface, the use of the PSL is required to access the B-3 BSI-DSZ-CC-0376-2006 Certification Report security functionality of the TOE. The PSL can be used with a Software development kit (SDK) from Infineon. The SDK itself is not part of the TOE. The other firmware part is the Self Test Software (STS) which controls the start- up of the chip. The STS configures all necessary parameters like keys for the MED. During the production test at the manufacturer Infineon Technologies AG the STS provides an interface to the test capabilities of the IC chip. The lock out of the test capabilities is also performed by the STS. The Security Target is written using the Smartcard IC Platform Protection Profile, Version 1.0 (BSI-PP-0002-2001) [8]. With reference to this Protection Profile, the smart card product life cycle is described in 7 phases. The development, production and operational user environment are described and referenced to these phases. TOE delivery of the IC is defined at the end of phase 3 as wafers or phase 4 as modules. The documentation is delivered from phase 2 to phase 1 in form of data carriers and/or paper documentation. In addition Embedded Software development tools are delivered from phase 2 to phase 1. These tools are not part of the TOE. The assumptions, threats and objectives defined in the Protection Profile [8] are used. To address additional security features of the TOE (e.g cryptographic services), the security environment as outlined in the PP [8] is augmented by an additional threat, policy, an assumption and security objectives accordingly. The TOE of this Security Target encloses the SLE88CFX4000P and seven additional chip derivates. The hardware and the IC Dedicated Software of the SLE88CFX4000P and the seven derivates are identical. The differences between the derivates are the NVM and ROM size and the availability of the coprocessor Crypto@1408BIT as shown in the following: Name of Chip NVM ROM User ROM Crypto@1408BIT coprocessor SLE88CFX4000P 400 kByte 80 kByte 0 kByte Enabled SLE88CFX4002P 400 kByte 80 kByte 160 kByte Enabled SLE88CFX3520P 352 kByte 80 kByte 0 kByte Enabled SLE88CFX2920P 292 kByte 80 kByte 0 kByte Enabled SLE88CF4000P 400 kByte 80 kByte 0 kByte Disabled SLE88CF4002P 400 kByte 80 kByte 160 kByte Disabled SLE88CF3520P 352 kByte 80 kByte 0 kByte Disabled SLE88CF2920P 292 kByte 80 kByte 0 kByte Disabled Table 1: Hardware configurations of the TOE In those derivates where the Crypto@1408BIT coprocessor is disabled, (i) the ACE driver, (ii) the patch loader mode of the Loader Filter Driver (part of B-4 Certification Report BSI-DSZ-CC-0376-2006 Security Function 2) and (iii) the RSA cryptography functionality (part of Security Function 9) are not available. In the following, the term SLE88CFX4000P includes all derivates. The firmware versions PSL V0.50.23_E107 and PSL V0.50.23_E110 can be tailored to remove functionality, which the user decides not to use. The tailored versions are called ´Basic PSL` and ´Standard PSL`. The untailored PSL is termed ´Extended PSL`. The functionality of each version is described in the guidance documentation of the TOE. The PSL version V0.50.23_E110 has the same functionality as the PSL V0.50.23_E107 and additionally the functionality RSAVERIFY. The TOE can be delivered to the user with PSL already tailored according to ´Basic PSL` or ´Standard PSL` for the derivate SLE88CFX4002P and SLE88CF4002P. For the derivates SLE88CFX4000P, SLE88CFX3520P, SLE88CFX2920P, SLE88CF4000P, SLE88CF3520P and SLE88CF2920P the PSL can be tailored by the user itself to the ´Basic PSL` or ´Standard PSL` during his manufacturing process, as described in the guidance documentation. The tailored version ´Basic PSL` of the TOE does not include the code implementing the AES (Advanced Encryption Standard) which is part of Security Function 9. The tailored version ´Standard PSL` of the TOE does not include the code of some non security enforcing functionality compared to ´Extended PSL`. Therefore this has no impact on any other security policy of the TOE. The TOE was evaluated against the claims of the Security Target [6]. The development and production environment in terms of the concepts and procedures regarding the CC assurance aspects ACM, ADO and ALC according to the Scheme Interpretation AIS38 [4] were evaluated by the Prüfstelle für IT-Sicherheit of the TÜV Informationstechnik GmbH. All product specific assurance aspects of the TOE (assurance classes ASE, ADV, AGD, ATE, AVA and the product specific aspects of ACM, ADO and ALC according to Scheme Interpretation AIS38 [4]) were evaluated by the T-Systems GEI GmbH, Prüfstelle IT-Sicherheit. The evaluation was completed on 13. June 2006. T-Systems GEI GmbH, Prüfstelle IT-Sicherheit as well as the Prüfstelle für IT- Sicherheit of the TÜV Informationstechnik GmbH are evaluation facilities (ITSEF) recognised by BSI. The sponsor, vendor and distributor is Infineon Technologies AG, Automotive, Industrial & Multimarket, Chipcard & Security IC´s, Am Campeon 1-12, 85579 Neubiberg, Germany 1.1 Assurance package The TOE security assurance requirements are based entirely on the assurance components defined in part 3 of the Common Criteria (see Annex C or [1], part B-5 BSI-DSZ-CC-0376-2006 Certification Report 3 for details). The TOE meets the assurance requirements of assurance level EAL 5 augmented (Evaluation Assurance Level 5 augmented). The following table shows the augmented assurance components.

For more details and application notes please refer to the Security Target [6], chapter 5.1.1 and 7.2. The security objectives for the TOE environment are outlined only by Non-IT requirements for the TOE environment, i.e. for (i) Design and Implementation of the Smartcard Embedded Software, (ii) Protection during Packaging, Finishing and Personalisation and (iii) Cipher Schemes. For details refer to the Security Target [6], chapter 5.2.2. These Security Functional Requirements are implemented by the TOE Security Functions: TOE Security Function Addressed issue SF1 Operating state checking SF2 Phase management with test mode lock-out SF3 Protection against snooping SF4 Data encryption and data disguising SF5 Random number generation 8 PP/ST: component is described in the PP but operations are performed in the ST. B-7 BSI-DSZ-CC-0376-2006 Certification Report TOE Security Function Addressed issue SF6 TSF self test SF7 Notification of physical attack SF8 Virtual Memory System (VMS) SF9 Cryptographic support SF10 NVM Tearing Save Write Table 5: TOE Security Functions SF1: Operating state checking Correct function of the TOE is only given in the specified range of the environmental operating parameters. To prevent an attack exploiting that circumstance, it is necessary to detect if the specified range is left. All operating signals are filtered to prevent malfunction and the operation state is monitored with sensors for the operating voltage, clock signal, frequency, temperature and electromagnetic radiation (e.g. light). The TOE falls into the defined secure state in case of a specified range violation. The defined secure state causes the chip internal reset process. SF2: Phase management with test mode lock-out During start-up of the TOE the decision for the user mode or the test mode is taken depending on several phase identifiers. If test mode is the active phase, the TOE requests authentication before any action (test mode lock-out). The phase management is used to provide the separation between the security enforcing functions and the user software. Before TOE delivery the TOE is set to user mode. In addition a chip identification mode exists which is active in all phases. If the chip identification mode is requested the chip identification data stored in a non modifiable NVM area is reported. During the production phase (phase 3) or after the delivery to the customer (phase 5 or phase 6), the TOE provides the possibility to load a user specific encryption key and user code and data encrypted into the empty (erased) NVM area as specified by the associated control information of the flash loader mode of the loader filter. After finishing the load operation, the flash loader mode is automatically deactivated, so that no second load operation with the flash loader mode is possible. During the operation of the TOE the PSL provides the possibility to load signed code and data in the NVM and RAM areas as specified by the associated control information of the patch loader mode of the loader filter. The public part of the used signing key is stored in the NVM. This function could be deactivated permanently by the user software. The B-8 Certification Report BSI-DSZ-CC-0376-2006 patch loader mode of the Loader Filter Driver is not available for those derivates with disabled Crypto@1408BIT coprocessor. SF3: Protection against snooping Several mechanisms, like topological design measures for disguise, protect the TOE against snooping the design or the user data during operation even if it is out of operation (power down). SF4: Data encryption and data disguising The memory content of the TOE is encrypted on chip to protect against data analysis on stored data as well as on internally transmitted data. Only the key owner has the possibility to read out data. To prevent interpretation of leaked information, randomness is inserted in the information. This function is specifically designed to prevent Differential Power Analysis (DPA) during cryptographic calculations (see chapter 9 and 10 of this report). SF5: Random number generation Random data are essential for cryptography as well as for physical security mechanisms. The TOE is equipped with a true random generator based on physical probabilistic effects. The random data can be used from the user software as well as from the security enforcing functions. The PSL provides tests as required by [4, AIS 31]. SF6: TSF self test The TOE has a hardware controlled self-test which can be started from the user software or is started directly to test SF5, SF7 and specific parts of SF1. Any attempt to modify the sensor devices will be detected from the test. SF7: Notification of physical attack The entire surface of the TOE is protected with the active shield. Attacks over the surface are detected when the shield lines are cut or get contacted. SF8: Virtual Memory System (VMS) The VMS in the TOE controls the address permissions of the so called privileged packages (memory areas) 1 and 2 and of the regular packages 3 to 15 and gives the software the possibility to define different access rights for the regular packages (memory areas) 16 to 255. The address permissions of the privileged package 0 are controlled by the hardware and the VMS. In case of an access violation the VMS will generate a trap. Then a trap service routine can react on the access violation. The policy of setting up the VMS and specifying the memory ranges for the regular packages 16 to 255 is defined from the user software in the upper layers. The two lower layers are given to the Secure Layer (SL) and the PSL. The Operating system has the layer 2 and the Debug B-9 BSI-DSZ-CC-0376-2006 Certification Report Package has the layer 3. The layer 4 to 15 are not used and reserved for future use. SF9: Cryptographic Support Specific cryptographic operations are provided by the TOE. The TOE is equipped with several hardware accelerators and software modules to support the standard cryptographic operation. The components are a combination of software and hardware unit to support DES encryption, a combination of software and hardware unit to support RSA cryptography and software units to support the AES and the SHA-1. RSA functionality is not available for those derivates with disabled Crypto@1408BIT coprocessor. AES availability depends on the selected PSL configuration. SF10: NVM Tearing Save Write The hardware of the NVM together with the PSL supports the TOE with a function to copy one data block with a defined maximum number of bytes or/and one or a bunch with a maximum number of data blocks of any data size to different NVM locations, under the protection of a data security mechanism. The data security mechanism keeps a backup copy of either the old or the new contents of all addressed NVM pages before they are overwritten. If the update of the data fails due to an unexpected card tearing, the old or the new contents of all target areas affected by the transaction is recovered at the next power-up. The NVM tearing save write detects errors that happen during the NVM write operation and corrects the errors to provide the correct function of the TOE. If a correction is not possible the TOE is forced into a secure state. As the final transition from test mode to user mode is performed before TOE delivery, all TOE Security Functions are applicable from TOE delivery at the end of phase 3 or 4 (depending on when TOE delivery takes place in a specific case) to phase 7. For more details please refer to the Security Target [6], chapter 6. 1.3 Strength of Function The TOE’s strength of functions is claimed ‘high’ (SOF-high) for specific functions as indicated in the Security Target [6], chapter 6. The rating of the strength of functions does not include the cryptoalgorithms suitable for encryption and decryption (see BSIG Section 4, Para. 3, Clause 2). For details see chapter 9 of this report. B-10 Certification Report BSI-DSZ-CC-0376-2006 1.4 Summary of threats and Organisational Security Policies (OSPs) addressed by the evaluated IT product The threats which were assumed for the evaluation and averted by the TOE and the organisational security policies defined for the TOE are specified in the Security Target [6] and can be summarised as follows. It is assumed that the attacker is a human being or a process acting on behalf of him. So called standard high-level security concerns defined in the Protection Profile [8] were derived from considering the end-usage phase (phase 7 of the life cycle as described in the Security Target) as follows: • manipulation of user data and of the smart card Embedded Software (while being executed/processed and while being stored in the TOE’s memories), • disclosure of user data and of the smart card Embedded Software (while being processed and while being stored in the TOE’s memories) and • deficiency of random numbers. These high-level security concerns are refined in the Protection Profile [8] and used by the Security Target [6] by defining threats on a more technical level for • Inherent Information Leakage, • Physical Probing, • Physical Manipulation, • Malfunction due to Environmental Stress, • Forced Information Leakage, • Abuse of Functionality and • Deficiency of Random Numbers. In addition, a threat concerning Memory Access Violation is specified. Phase 1 and the phases from TOE Delivery up to the end of phase 6 are covered by assumptions (see below). The development and production environment starting with phase 2 up to TOE Delivery are covered by an organisational security policy outlining that the IC developer / manufacturer must apply the policy “Protection during TOE Development and Production (P.Process-TOE)” so that no information is unintentionally made available for the operational phase of the TOE. The Policy ensures confidentiality and integrity of the TOE and its related design information and data. Access to samples, tools and material must be restricted. A specific additional security functionality for DES, Triple-DES, RSA and AES encryption and decryption as well as the hash algorithm SHA-1 must be provided by the TOE according to an additional security policy defined in the Security Target. B-11 BSI-DSZ-CC-0376-2006 Certification Report Objectives are taken from the Protection Profile plus additional ones related to the additional policy. 1.5 Special configuration requirements The TOE has two different operating modes, user mode and test mode. The application software being executed on the TOE can not use the test mode. The TOE is delivered as a hardware unit at the end of the IC manufacturing process (phase 3) or at the end of IC Packaging (phase 4). At this point in time the test mode is disabled and the operating system software including the PSL IC dedicated SW part of the TOE is already stored in the non-volatile memories of the chip or the loader is configured to be able to load embedded software into the NVM after phase 4. The derivates of the TOE as outlined in chapter 1 have identical hardware and IC Dedicated Software. The differences between the derivates are the NVM and ROM size and the availability of the Crypto@1408BIT coprocessor. This hardware configuration is done before TOE delivery. The developer of the Embedded Software may tailor the PSL software to ´Basic PSL` or ´Standard PSL`as described in the guidance documentation of the TOE. This is done in phase 1 and need no configuration after TOE delivery. Thus, there are no special procedures for generation or installation that are important for a secure use of the TOE after TOE delivery. The further production and delivery processes, like the smart card finishing process, personalisation and the delivery of the smart card to an end user, have to be organised in a way that excludes all possibilities of physical manipulation of the TOE. There are no special security measures for the start-up of the TOE besides the requirement that the controller has to be used under the well-defined operating conditions and that the requirements on the software have to be applied as described in the user documentation and chapter 10 of this report. 1.6 Assumptions about the operating environment Since the Security Target claims conformance to the Protection Profile [8], the assumptions defined in section 3.2 of the Protection Profile are valid for the Security Target of this TOE. With respect to the life cycle defined in the Security Target, Phase 1 and the Phases from TOE Delivery up to the end of Phase 6 are covered by these assumptions from the PP: The developer of the smart card Embedded Software (Phase 1) must ensure: • the appropriate “Usage of Hardware Platform (A.Plat-Appl)” while developing this software in Phase 1. Therefore, it has to be ensured, that the software fulfils the assumptions for a secure use of the TOE. In particular the assumptions imply that developers are trusted to develop software that fulfils the assumptions. B-12 Certification Report BSI-DSZ-CC-0376-2006 • the appropriate “Treatment of User Data (A.Resp-Appl)” while developing this software in Phase 1. The smart card operating system and the smart card application software have to use security relevant user data of the TOE (especially keys and plain text data) in a secure way. It is assumed that the Security Policy as defined for the specific application context of the environment does not contradict the Security Objectives of the TOE. Only appropriate secret keys as input for the cryptographic function of the TOE have to be used to ensure the strength of cryptographic operation. Protection during Packaging, Finishing and Personalisation (A.Process-Card) is assumed after TOE Delivery up to the end of Phase 6, as well as during the delivery to Phase 7. The following additional assumption is assumed in the Security Target: • Key-dependent functions (if any) shall be implemented in the smart card Embedded Software in a way that they are not susceptible to leakage attacks (A.Key-Function). 1.7 Disclaimers 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.

The “mini-operating system” software has to be disabled by the user and is not a part of any of the evaluated configurations. The parts of the PSL needed to tailor the TOEs variant of the PSL at the user’s (i.e. application software developer) site are delivered to the user. These parts of the TOE are identified by a name of the data file and by a hash value. The guidance documentation shows how to tailor the PSL to evaluated variants. In case of delivery with SDK 2.9 SP4, the SDK 2.9 SP4 itself is not a part of the TOE and beyond its delivery aspect. B-14 Certification Report BSI-DSZ-CC-0376-2006 As the hardware of all derivates listed in table 6 is identical, the number m8830 of the SLE88CFX4000P is visible on the chip surface of all derivates. The non-ISO Reset of the chip allows the user to get chip identification information. Bytes 4 to 5 are the chip type bytes as described in the SLE88CFXxxxxP PSL & Security Reference Manual [11], appendix A5. The chip type byte identifies the version of the TOE-ICs: • for SLE88CFX4000Pm8830b17: offset byte 4: 13 hex; offset byte 5: 51 hex • for SLE88CFX4002Pm8834b17: offset byte 4: 18 hex; offset byte 5: 51 hex • for SLE88CFX3520Pm8847b17: offset byte 4: 1A hex; offset byte 5: 51 hex • for SLE88CFX2920Pm8849b17: offset byte 4: 1C hex; offset byte 5: 51 hex • for SLE88CF4000P/m8845b17: offset byte4: 17 hex; offset byte 5: 51 hex • for SLE88CF4002P/m8846b17: offset byte4: 19 hex; offset byte 5:51 hex • for SLE88CF3520P/m8848b17: offset byte4: 1B hex; offset byte 5:51 hex • for SLE88CF2920P/m8850b17: offset byte4: 1D hex; offset byte 5: 51 hex The first nibble of the offset byte 6 (batch number) gives the production line indicator which is „2“ for all versions of the TOE, as the evaluated TOE is produced in Dresden. The PSL-code is embedded into the ROM mask by Infineon or loaded into the NVM as part of the embedded software. It is identified by its unique version number. The Embedded Software has access to the PSL version number for a specific chip by reading the registry entry ’VAL_PSL_VERSION’. The STS-code is embedded into the ROM mask by Infineon. It is identified by its unique version number. The STS version is stored in the last four bytes of the Chip Identification Number and is “00 0e 0e 0e” which corresponds to “562”. To support Embedded Software development and simulation on bond-out chips, a PSL object file is delivered to the Embedded Software developer. The Embedded Software developer should verify the PSL version. The delivery process from Infineon to their customers (to phase 5 or phase 6 of the life cycle) guarantees, that the customer is aware of the exact versions of the different parts of the TOE as outlined above. To ensure that the customer receives the evaluated version of the chip, either • he has to personally pick up the TOE (IC on Wafers or Modules) at the Infineon Warehouse in Regensburg (VKL-Rgb) or Wuxi to (see part D, annex A of this report) or • the TOE (IC on Wafers or Modules) is sent as a secured transport by specific haulage companies from the Infineon Warehouse in Regensburg (VKL-Rgb) or from Wuxi directly or via one of three distribution centers (DC E for Europe, DC A for Asia and DC U for the United States) to the customer. The sender informs the receiver that a delivery was started; after the delivery was received it has to be checked according to the B-15 BSI-DSZ-CC-0376-2006 Certification Report consignment notes and the sender is to be informed immediately about result of the check. TOE documentation is delivered either as hardcopy or as softcopy (encrypted) according to defined mailing procedures. The above mentioned additional PSL object file is delivered as softcopy (encrypted object file) to the Embedded Software developer according to defined mailing procedures. Defined procedures at the development and production sites of Infineon guarantee that the right versions of the PSL and STS are implemented into a specific ROM mask for a TOE IC. 3 Security Policy The security policy of the TOE is defined to provide basic Security Functions 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 symmetric cryptographic block cipher algorithms (DES, Triple-DES, AES) to ensure the confidentiality of plain text data by encryption and to support secure authentication protocols and it will provide a random number generator. Additionally the TOE implements RSA cryptography and SHA-1 functionality9 . As the TOE is a hardware security platform, the security policy of the TOE is also defined to provide protection against leakage of information (e.g. to ensure the confidentiality of cryptographic keys during DES, Triple-DES and AES cryptographic functions performed by the TOE), protection against physical probing, malfunctions, 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 Functions (security mechanisms and associated functions) provided by the TOE. 4 Assumptions and Clarification of Scope The smart card operating system and the application software stored in the User ROM and in the NVM are not part of the TOE. The code in the Test ROM of the TOE (IC Dedicated Test Software) is used by the TOE manufacturer to check the chip function before TOE Delivery. This was considered as part of the evaluation under the CC assurance aspects ALC for relevant procedures and under ATE for testing. 9 The availability of RSA and AES functionality depends on the derivate and the PSL configuration. B-16 Certification Report BSI-DSZ-CC-0376-2006 The TOE is delivered as a hardware unit at the end of the chip manufacturing process (phase 3 of the life cycle defined) or at the end of the IC packaging into modules (phase 4 of the life cycle defined). At these specific points in time the test mode is completely disabled. During the operation of the TOE the PSL provides the possibility to load signed code and data in the NVM and RAM areas as specified by the associated control information (loader function). This function can be deactivated by the user software. (see chapter 10 of this report for secure usage) In case the PSL software is used as ´Basic PSL`, the cryptographic functionality of AES calculation as part of SF9 Cryptographic Support is not available to the embedded software. Additional cryptographic functions included in the PSL but not described within SF9 is not part of the evaluated security functionality. The smart card applications need the Security Functions of the smart card operating system based on the security features of the TOE. With respect to security the composition of this TOE, the operating system, and the smart card application is important. Within this composition the security functionality is only partly provided by the TOE and causes dependencies between the TOE Security Functions and the functions provided by the operating system or the smart card application on top. These dependencies are expressed by environ- mental and secure usage assumptions as outlined in the user documentation. Within this evaluation of the TOE several aspects were specifically considered to support a composite evaluation of the TOE together with an embedded smart card application software (i.e. smart card operating system and application). This was necessary as Infineon Technologies AG is the TOE developer and manufacturer and responsible for specific aspects of handling the embedded smart card application software in its development and production environment. For those aspects refer to part B, chapter 9 of this report. The full evaluation results are applicable for chips from the semiconductor factory in Dresden, each labelled by the production line indicator „2“. 5 Architectural Information The Infineon Smart Card IC (Security Controller) SLE88CFX4000P/m8830b17, SLE88CFX4002P/m8834b17, SLE88CFX3520P/m8847b17, SLE88CFX2920P/ m8849b17, SLE88CF4000P/m8845b17, SLE88CF4002P/m8846b17, SLE88CF 3520P/m8848b17 and SLE88CF2920P/m8850b17 each with PSL V0.50.23_ E107 or PSL V0.50.23_E110 and specific IC Dedicated Software is an integrated circuit (IC) providing a hardware and software platform (Platform Support Layer PSL) to a smart card Embedded Software. A top level block diagram and a list of subsystems can be found within the TOE description of the Security Target [6]. The complete hardware description, the complete instruction set and the programmers interfaces to the PSL of the Infineon SLE88CFX4000P smart card controller can be found in the guidance documentation [12] and [13]. B-17 BSI-DSZ-CC-0376-2006 Certification Report For the implementation of the TOE Security Functions basically the components 32-bit proprietary CPU, (Triple-) DES Co-Processor, numeric coprocessor (Crypto@1408BIT), Random Number Generator (RNG), Virtual Memory System (VMS), Security Sensors and Filters, Memory Encryption and software drivers within the Platform Support Layer software (PSL) are used. Security measures for physical protection are realised within the layout of the whole circuitry. Logical security measures are implemented in both the circuitry of the hardware and in the software of the PSL. The API of the Platform Support Layer software (PSL) provide the user interface to all security functions of the TOE where they can be configured or used by the user (i.e. smart card operating system and/or the smart card Embedded Software). The modular arithmetic functions provided by the PSL are designed to help the user to implement different asymmetric cryptographic algorithms (RSA). AES and SHA-1 functionality is provided by PSL software. The TOE IC Dedicated Test Software (STS), stored on the chip, is used for testing purposes during production only and is completely separated from the use of the embedded software by disabling before TOE delivery. 6 Documentation The documentation [11] to [15] is provided with the product by the developer to the customer for secure usage of the TOE in accordance with the Security Target. Additional guidance as outlined in chapter 10 of this report has to be followed. Note that the customer who buys the TOE is normally the developer of the operating system and/or application software which will use the TOE as hard- ware computing platform to implement the software (operating system / application software) which will use the TOE. To support a composite evaluation as defined in AIS 36 [4], the document ETR- lite [10] is provided for the composite evaluator. 7 IT Product Testing The tests performed by the developer can be divided into following categories: 1) 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); 2) tests which are performed in a simulation environment for analogue and for digital simulations; 3) regression tests which are performed for the IC Dedicated Test Software (PSL) and for the IC Dedicated Support Software (STS) on emulator versions of the TOE or within the simulation of chip in special hardware; B-18 Certification Report BSI-DSZ-CC-0376-2006 4) 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; 5) 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. 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 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 developers 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 evaluators supplied evidence that the actual versions 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). Several samples of the TOE were used for the evaluator’s tests in the evaluators laboratory and at the developer’s site. The samples used to perform the tests are provided by the wafer fab Dresden. Since the characterisation tests are an important part of the initial tests that are requested for the release of the production of a wafer fab the results are only valid for the fab Dresden (see part D, annex A of this report). The test results are valid for all hardware derivates of the TOE containing the same software (PSL, STS and TNVM), as the only difference is the configured (by software means) size of the available NVM to the user, the size of ROM made available to the user and the availability of the Crypto@1408BIT B-19 BSI-DSZ-CC-0376-2006 Certification Report coprocessor. These configuration options have no impact on evaluation test results. The test results are valid for “Basic PSL”, “Extended PSL” and “Standard PSL” on all derivates. 8 Evaluated Configuration The TOE is identified by the version Infineon Smart Card IC (Security Controller) SLE88CFX4000P/m8830b17, SLE88CFX4002P/m8834b17, SLE88CFX3520P/m8847b17, SLE88CFX2920P/m8849b17, SLE88CF4000P/ m8845b17, SLE88CF4002P/m8846b17, SLE88CF3520P/m8848b17 and SLE88CF2920P/m8850b17 each with PSL V0.50.23_E107 or PSL V0.50.23_E110 and specific IC Dedicated Software with production line indicator “2” (Dresden). The embedded software developer decides on configuration of the PSL software as described above. The TOE has only one fixed evaluated configuration at the time of delivery to phase 4 resp. 5. All information of how to use the TOE and its Security Functions by the software is provided within the user documentation. The TOE has two different operating modes, user mode and test mode. The application software being executed on the TOE can not use the test mode. Thus, the evaluation was mainly performed in the user mode. For all evaluation activities performed in test mode, there was a rationale why the results are valid for the user mode, too. 9 Results of the Evaluation The Evaluation Technical Report (ETR), [7] was provided by the ITSEF T-Systems GEI GmbH, Prüfstelle IT-Sicherheit 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 identical with EAL4. For components beyond EAL4 the methodology was defined in co- ordination with the Certification Body [4, AIS 34]). For smart card IC specific methodology the CC supporting documents (i) The Application of CC to Integrated Circuits (ii) Application of Attack Potential to Smartcards and (iii) ETR-lite – for Composition and ETR-lite – for composition: Annex A Composite smartcard evaluation: Recommended best practice (see [4, AIS 25, AIS 26 and AIS 36]) and [4, AIS 31] (Functionality classes and evaluation methodology for physical random number generators) were used. The assurance refinements outlined in the Security Target were followed in the course of the evaluation of the TOE. B-20 Certification Report BSI-DSZ-CC-0376-2006 The evaluation results of the development and production environment in terms of the concepts and procedures regarding the CC assurance aspects ACM, ADO and ALC according to the Scheme Interpretation AIS38 [4] were provided by the ITSEF of TÜV Informationstechnik GmbH. The verdicts for the CC, Part 3 assurance components (according to EAL 5 augmented and the class ASE for the Security Target evaluation) are summarised in the following table.

Therefore the scheme interpretations AIS 26 and AIS31 (see [4]) were used. SPA/DPA analysis for RSA-Functionality is not fully part of this certification (please refer to chapter 10 of this report). The rating of the strength of functions does not include the cryptoalgorithms suitable for encryption and decryption (see BSIG Section 4, Para. 3, Clause 2). This holds for (i) the TOE Security Function SF9 -- which is a) DES and Triple-DES encryption and decryption and b) RSA encryption and decryption B-22 Certification Report BSI-DSZ-CC-0376-2006 c) AES encryption and decryption -- and (ii) for other usage of encryption and decryption within the TOE. For specific evaluation results regarding the development and production environment see annex A in part D of this report. The code in the Test ROM of the TOE (IC Dedicated Test Software) is used by the TOE manufacturer to check the chip function before TOE delivery. This was considered as part of the evaluation under the CC assurance aspects ALC for relevant procedures and under ATE for testing. The results of the evaluation are only applicable to the TOE as identified in table 6, produced in the semiconductor factory in Dresden, labelled by the production line indicator „2“ within the chip identification number in the NVM, and the firmware and software versions as indicated in table 6 and the documentation listed in table 6, too. The evaluation results are valid for all hardware derivates of the TOE containing the same software (PSL, STS and TNVM), as the only difference is the configured (by software means) size of the available NVM to the user and the size of ROM made available to the user. Both configuration options have no impact on evaluation results. Disabling of the Crypto@1408BIT coprocessor for specific derivates was considered. The evaluation results are valid for “Basic PSL”, “Extended PSL” and “Standard PSL” on all derivates. The evaluation results cannot be extended to further versions/derivates of the TOE and/or another production sites without any extra investigations. The validity can be extended to new versions and releases of the product, provided the sponsor applies for re-certification or assurance continuity of the modified product, in accordance with the procedural requirements, and the evaluation of the modified product does not reveal any security deficiencies. To support a composite evaluation of the TOE together with a specific smart card embedded software additional evaluator actions were performed during the TOE evaluation. The results are documented in the ETR-lite [10] according to [4, AIS 36]. Therefore, the interface between the smart card embedded software developer and the developer of the TOE was examined in detail. 10 Comments/Recommendations The operational documents [11] - [15] contain necessary information about the usage of the TOE and all security hints therein have to be considered by the smart card Embedded Software developer. In the following, specific items are listed: The document [13] guides on tailoring of the PSL variant during development (by the user) of the application software and on removing the “mini-operating system” which is not a part of a certified configuration. Infineon will also provide B-23 BSI-DSZ-CC-0376-2006 Certification Report the Security Target to customers. This includes the assumptions about the environment and usage of the TOE and the security functions provided by the TOE. Besides the requirements to follow the instructions in the user guidance documents (especially section 4, [11] and the corresponding delta information in [14]) and to ensure fulfilment of the assumptions about the environment in the Security Target, the following items have to be followed: 1. The virtual memory system must be properly initialised and managed in order to fulfil the security policy defined by application developer. The security and the PSL layer maintain their own security policy. The application software (i.e. operating system) is responsible for using the virtual memory system with respect to this policy, i.e. not to change these protections by any means. It is further responsible for using only the VMS API from PSL in a manner that is sufficient to fulfil its own security policies. Note that the PSL driver ensures that the logical scrambling (through random mapping of virtual to physical address on memory allocation) is realised. 2. The user should check for the sufficient physical address randomisation of data areas (RAM, NVM) when the user decides to use the fixed mapping features offered by the development tools. 3. The user must also take care about DPA/SPA security when using the SHA-1 with secret key data (i.e. keyed hash) as the SHA-1 implementation is not claimed to be DPA/SPA resistant and therefore its respective resistance was not tested. 4. Requirements for Embedded Software development are addressed by the IC user guidance [11] to [14]. The concrete measures being applied by the developer of the Smartcard Embedded Software must be evaluated during the composite evaluation. In particular the effectiveness of DPA/SPA countermeasures in the usage of the SF9, RSA (ModPow API) and ModInv API must be evaluated as the TOE implements by itself only basic functionality.

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 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 6.1) “Table 6.1 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 2 of this Part 3. More precisely, each EAL includes no more than one 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 CC 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 extended with explicitly stated assurance requirements.” C-3 Certification Report BSI-DSZ-CC-0376-2006 “Assurance Class Assurance Family Assurance Components by Evaluation Assurance Level EAL1 EAL2 EAL3 EAL4 EAL5 EAL6 EAL7 Configuration management ACM_AUT 1 1 2 2 ACM_CAP 1 2 3 4 4 5 5 ACM_SCP 1 2 3 3 3 Delivery and operation ADO_DEL 1 1 2 2 2 3 ADO_IGS 1 1 1 1 1 1 1 Development ADV_FSP 1 1 1 2 3 3 4 ADV_HLD 1 2 2 3 4 5 ADV_IMP 1 2 3 3 ADV_INT 1 2 3 ADV_LLD 1 1 2 2 ADV_RCR 1 1 1 1 2 2 3 ADV_SPM 1 3 3 3 Guidance documents AGD_ADM 1 1 1 1 1 1 1 AGD_USR 1 1 1 1 1 1 1 Life cycle support ALC_DVS 1 1 1 2 2 ALC_FLR ALC_LCD 1 2 2 3 ALC_TAT 1 2 3 3 Tests ATE_COV 1 2 2 2 3 3 ATE_DPT 1 1 2 2 3 ATE_FUN 1 1 1 1 2 2 ATE_IND 1 2 2 2 2 2 3 Vulnerability assessment AVA_CCA 1 2 2 AVA_MSU 1 2 2 3 3 AVA_SOF 1 1 1 1 1 1 AVA_VLA 1 1 2 3 4 4 Table 6.1: Evaluation assurance level summary” C-4 BSI-DSZ-CC-0376-2006 Certification Report Evaluation assurance level 1 (EAL1) - functionally tested (chapter 6.2.1) "Objectives EAL1 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. EAL1 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 EAL1 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, and that it provides useful protection against identified threats.“ Evaluation assurance level 2 (EAL2) - structurally tested (chapter 6.2.2) "Objectives EAL2 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 practice. As such it should not require a substantially increased investment of cost or time. EAL2 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 (EAL3) - methodically tested and checked (chapter 6.2.3) "Objectives EAL3 permits a conscientious developer to gain maximum assurance from positive security engineering at the design stage without substantial alteration of existing sound development practices. EAL3 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.“ C-5 Certification Report BSI-DSZ-CC-0376-2006 Evaluation assurance level 4 (EAL4) - methodically designed, tested, and reviewed (chapter 6.2.4) "Objectives EAL4 permits a developer to gain maximum assurance from positive security engineering based on good commercial development practices which, though rigorous, do not require substantial specialist knowledge, skills, and other resources. EAL4 is the highest level at which it is likely to be economically feasible to retrofit to an existing product line. EAL4 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 (EAL5) - semiformally designed and tested (chapter 6.2.5) "Objectives EAL5 permits a developer to gain maximum assurance from security engineering based upon rigorous commercial development practices supported by moderate application of specialist security engineering techniques. Such a TOE will probably be designed and developed with the intent of achieving EAL5 assurance. It is likely that the additional costs attributable to the EAL5 requirements, relative to rigorous development without the application of specialised techniques, will not be large. EAL5 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 (EAL6) - semiformally verified design and tested (chapter 6.2.6) "Objectives EAL6 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. EAL6 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.“ C-6 BSI-DSZ-CC-0376-2006 Certification Report Evaluation assurance level 7 (EAL7) - formally verified design and tested (chapter 6.2.7) "Objectives EAL7 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 EAL7 is currently limited to TOEs with tightly focused security functionality that is amenable to extensive formal analysis.“ C-7 Certification Report BSI-DSZ-CC-0376-2006 Strength of TOE security functions (AVA_SOF) (chapter 14.3) AVA_SOF Strength of TOE security functions "Objectives Even if a TOE security function cannot be bypassed, deactivated, or corrupted, it may still be possible to defeat it because there is a vulnerability in the concept of its underlying security mechanisms. For those functions a qualification of their security behaviour can be made using the results of a quantitative or statistical analysis of the security behaviour of these mechanisms and the effort required to overcome them. The qualification is made in the form of a strength of TOE security function claim.“ Vulnerability analysis (AVA_VLA) (chapter 14.4) AVA_VLA Vulnerability analysis "Objectives Vulnerability analysis is an assessment to determine whether vulnerabilities identified, during the evaluation of the construction and anticipated operation of the TOE or by other methods (e.g. by flaw hypotheses), could allow users to violate the TSP. Vulnerability analysis deals with the threats that a user will be able to discover flaws that will allow unauthorised access to resources (e.g. data), allow the ability to interfere with or alter the TSF, or interfere with the authorised capabilities of other users.“ "Application notes A vulnerability analysis is performed by the developer in order to ascertain the presence of security vulnerabilities, and should consider at least the contents of all the TOE deliverables including the ST for the targeted evaluation assurance level. The developer is required to document the disposition of identified vulnerabilities to allow the evaluator to make use of that information if it is found useful as a support for the evaluator's independent vulnerability analysis.“ "Independent vulnerability analysis goes beyond the vulnerabilities identified by the developer. The main intent of the evaluator analysis is to determine that the TOE is resistant to penetration attacks performed by an attacker possessing a low (for AVA_VLA.2), moderate (for AVA_VLA.3) or high (for AVA_VLA.4) attack potential.“ C-8 BSI-DSZ-CC-0376-2006 Certification Report D Annexes List of annexes of this certification report Annex A: Evaluation results regarding development and production environment D-3 D-1 BSI-DSZ-CC-0376-2006 Certification Report This page is intentionally left blank.
