It provides a hardware platform for a smart card operating system. The evaluation was performed as a re-evaluation process based on BSI-DSZ-CC-0293- 2005. The TOE was re-evaluated because of specific changes of security features. Figure 1: block diagram of the NXP P5CC036V1D The TOE is the NXP chip P5CC036V1D (shown in the diagram) and P5CC009V1D with specific IC dedicated Software, composed of a processing unit, security components, I/O ports, volatile and non-volatile memories (4608 Bytes RAM, 128 Kbytes Application-ROM for the P5CC036V1D / 96 KBytes Application-ROM for the P5CC009V1D, 36 KBytes EEPROM for the P5CC036V1D / 10 Kbytes EEPROM for the P5CC009V1D), a Triple- DES, a FameXE co-processor, a Random number generator, two 16-bit Timers, an Interrupt Module, a Memory Management Unit and an UART for ISO 7816 Interface. The Security Target [6] is the basis for this certification. It is based on the certified Protection Profile Smartcard IC Platform Protection Profile, Version 1.0, BSI-PP-0002- 2001 [10]. The TOE Security Assurance Requirements (SAR) are based entirely on the assurance components defined in Part 3 of the Common Criteria (see part C or [1], Part 3 for details). The TOE meets the Assurance Requirements of the Evaluation Assurance Level EAL 5 augmented by ALC_DVS.2, AVA_MSU.3, AVA_VLA.4. 12 / 36 BSI-DSZ-CC-0583-2009 Certification Report The TOE Security Functional Requirements (SFR) relevant for the TOE are outlined in the Security Target [6] and [9], chapter 5.1. 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 Functions: TOE Security Function Addressed issue F.RNG Random Number Generator F.HW_DES Triple-DES Co-Processor F.OPC Control of Operating Conditions F.PHY Protection against Physical Manipulation F.LOG Logical Protection F.COMP Protection of Mode Control F.MEM_ACC Memory Access Control F.SFR_ACC Special Function Register Access Control Table 1: TOE Security Functions For more details please refer to the Security Target [6] and [9], chapter 6. The claimed TOE’s Strength of Functions 'high' (SOF-high) for specific functions as indicated in the Security Target [6] and [9], chapter 6.1 is confirmed. 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. The assets to be protected by the TOE are defined in the Security Target [6] and [9], chapter 3.1. Based on these assets the TOE Security Environment is defined in terms of Assumptions, Threats and Organisational Security Policies. This is outlined in the Security Target [6] and [9], chapter 3.3 and 3.4. This certification covers the following configurations of the TOE: ● Major configuration NXP P5CC036V1D has the following properties that are relevant with regard to the configuration: The size of the EEPROM is 36 kBytes, the size of the ROM usable for the Smart Card Embedded Software is 128 kBytes. ● Major configuration NXP P5CC009V1D has the following properties that are relevant with regard to the configuration: The size of the EEPROM is 10 kBytes, the size of the ROM usable for the Smart Card Embedded Software is 96 kBytes. Find more details in the Security Target [6] and [9], chapter 2.2. 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. 13 / 36 Certification Report BSI-DSZ-CC-0583-2009 2 Identification of the TOE The Target of Evaluation (TOE) is called: NXP Smart Card Controller P5CC036V1D and P5CC009V1D each with specific IC dedicated Software The following table outlines the TOE deliverables: No Type Identifier Release Date Form of Delivery 1 or HW NXP P5CC036V1D Secure Smart Card Controller V1D T503D.gds2_ 20040915 Wafer, (dice include reference T503D) HW NXP P5CC009V1D Secure Smart Card Controller V1D T503D.gds2_ 20040915 Wafer, (dice include reference T503D) 2 SW Test ROM Software (the IC dedicated Test Software) 1.4 2004-08-16 test ROM on the chip (tmfos.lst, V1.4) 3 SW Boot ROM Software (part of the IC dedicated Support Software) 1.7 boot.asm 2004-03-09 test ROM on the chip (tmfos.lst, V1.4) 4 DOC Data Sheet, P5CC036 [12] 3.3 2005-06-27 electronic document 5 DOC Instruction Set [13] 1.1 2006-07-04 electronic document 6 DOC Guidance, Delivery and Operation Manual for the P5CC009V1D, P5CC036V1D [14] 1.2 2009-01-08 electronic document Table 2: Deliverables of the TOE The hardware part of the TOE is identified by P5CC036V1D or P5CC009V1D and its specific GDS-file. A so-called nameplate (on-chip identifier) is coded in a metal mask onto the chip during production and can be checked by the customer, too. The nameplate T503D is specific for the SSMC (Singapore) production site as outlined in the guidance documentation [14]. This nameplate identifies Version V1D of the hardware, but does not identify specifically the TOE configurations. For identification of a specific configuration, the Device Coding Bytes stored in the EEPROM can be used (see [12], chapter 11.7): ● The value 0E hex in Device Coding Byte DC2 identifies the chip P5CC036V0A. ● The value 0C hex in Device Coding Byte DC2 identifies the chip P5CC009V0A. Items 2 and 3 in table 2 are not delivered as single pieces, but included in the Test ROM part of the chip. They are identified by their unique version numbers. The delivery process from NXP to their customers (to phase 4 or phase 5 of the life cycle) guarantees, that the customer is aware of the exact versions of the different parts of the TOE as outlined above. 14 / 36 BSI-DSZ-CC-0583-2009 Certification Report 3 Security Policy The security policy of the TOE is 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 a symmetric cryptographic block cipher algorithm (Triple-DES) to ensure the confidentiality of plain text data by encryption and to support secure authentication protocols and it will provide a random number generation of appropriate quality. 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 cryptographic functions performed by the TOE), protection against physical probing, malfunctions, physical manipulations, against access for code and data memory and against abuse of functionality. 4 Assumptions and Clarification of Scope The Assumptions defined in the Security Target and some aspects of Threats and Organisational Security Policies are not covered by the TOE itself. These aspects lead to specific Security Objectives to be fulfilled by the TOE-Environment. The following topics are of relevance: Protection during Packaging, Finishing and Personalization, Usage of Hardware Platform, Treatment of User Data, Check of initialisation data by the Smart Card Embedded Software, Usage of Key-dependent Functions. Details can be found in the Security Target [6] resp. [9] chapter 3 and in the Protection Profile BSI-PP-0002-2001 [10]. 5 Architectural Information The NXP P5CC036V1D Smart Card Controller is an integrated circuit (IC) providing a hardware platform to a Smart Card operating system and 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] resp. [9]. The complete hardware description and the complete instruction set of the NXP P5CC036V1D Smart Card Controller can be found in the “Data Sheet, P5CC036”, [12] and “Instruction Set, SmartMX-Family”, [13]. For the implementation of the TOE Security Functions basically the components 8-bit CPU, Special Function Registers, Triple-DES Co-Processor, FameXE Co-Processor, Random Number Generator (RNG), Power Module with Security Sensors and Filters are used. The CPU is equipped with a Memory Management Unit and provides different CPU Modes in order to separate different applications running on the TOE. Security measures for Physical Protection are realized within the layout of the whole circuitry. The Special Function Registers provide the interface to the security functions of the TOE. 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. 15 / 36 Certification Report BSI-DSZ-CC-0583-2009 7 IT Product Testing The hardware platform tests performed by the developer were divided into six 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 with different tools for the analogue circuitries and for the digital parts of the TOE; 3. Regression tests of the hardware within a simulation environment based on special software dedicated only for the regression tests; 4. Characterisation and verification tests to release the TOE to production; 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). The evaluators were able to repeat the tests of the developer either using the library of programs, tools and prepared chip samples delivered to the evaluator or at the developers site. They performed independent tests to supplement, augment and to verify the tests performed by the developer. 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. Both, Philips P5CC036V1D and P5CC009V1D with specific IC dedicated Software Secure Smart Card Controller were tested by the evaluator. 8 Evaluated Configurations There are two major configuration options, denoted by different product names. They are identical except for the memories accessible for the user (128 KBytes Application-ROM and 36 KBytes EEPROM for the P5CC036V1D; 96 KBytes Application-ROM and 10 KBytes EEPROM for the P5CC009V1D). Both major configurations of the TOE support further configuration options as outlined in the Security Target [6] resp. [9], chapter 2.2. All TSF are active and usable. Information on how to use the TOE and its security functions by the software is provided within the user documentation. 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 EAL4 extended by advice of the Certification Body for components beyond EAL 4 and guidance specific for the technology of the product [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 16 / 36 BSI-DSZ-CC-0583-2009 Certification Report (iii) ETR-lite – for Composition and ETR-lite – for Composition: Annex A Composite smartcard evaluation: Recommended best practice (see [4], AIS 25, AIS 26, AIS 36 and AIS 31]) were used. The assurance refinements outlined in the Security Target were followed in the course of the evaluation of the TOE. As a result of the evaluation the verdict PASS is confirmed for the following assurance components: ● All components of the class ASE ● All components of the EAL 5 package as defined in the CC (see also part C of this report) ● The components ALC_DVS.2, AVA_MSU.3, AVA_VLA.4, 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-0293-2005, re-use of specific evaluation tasks was possible. The focus of this re-evaluation was on the optimization of security features. The evaluation has confirmed: ● PP Conformance: Smartcard IC Platform Protection Profile, Version 1.0, BSI-PP-0002-2001 [10] ● for the Functionality: BSI-PP-0002-2001 conformant plus product specific extensions Common Criteria Part 2 extended ● for the Assurance: Common Criteria Part 3 conformant EAL 5 augmented by ALC_DVS.2, AVA_MSU.3, AVA_VLA.4 ● The following TOE Security Functions fulfil the claimed Strength of Function : high F.RNG: random number generator according to AIS 31; Functionality class P2 High in combination with online tests to be implemented by the embedded software as specified in [14]. F.LOG: contributing to the leakage attacks especially for F.HW_DES (Triple- DES Co-processor) by SPA/DPAcountermeasures together with the guidance given in [14]. In order to assess the strength of function the scheme interpretations AIS 25, 26 and AIS 31 (see [4]) were used. 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 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: 17 / 36 Certification Report BSI-DSZ-CC-0583-2009 – the TOE Security Function F.HW_DES implements Triple-DES encryption and decryption The strength of the cryptographic algorithms was not rated in the course of this evaluation (see BSIG Section 4, Para. 3, Clause 2). But Cryptographic functions with a security level of 80 bits or lower can no longer be regarded as secure against attacks with high attack potential without considering the application context. Therefore for these functions 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' (www.bsi.bund.de). The cryptographic function 2-key or 3-key Triple DES provided by the TOE has got a security level of maximum 80 Bits (in general context). 10 Obligations and notes for the usage of the TOE The operational documentation [12] - [14] as outlined in table 2 contain necessary information about the usage of the TOE and all security hints therein have to be considered. For secure usage of the TOE the fulfilment of the assumptions about the environment in the Security Target [6] resp. [9] and the fulfilment of the recommendations written in the ETR for Composition [11], chapter 6 has to be taken into account. The advice by the hardware user guidance [14] given in section 5.1 must be implemented by the user. 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]). 18 / 36 BSI-DSZ-CC-0583-2009 Certification Report 12 Definitions 12.1 Acronyms BSI Bundesamt für Sicherheit in der Informationstechnik / Federal Office for Information Security, Bonn, Germany BSIG BSI-Errichtungsgesetz CCRA Common Criteria Recognition Arrangement CC Common Criteria for IT Security Evaluation CPU Central Processing Unit DES Data Encryption Standard; symmetric block cipher algorithm DPA Differential Power Analysis EAL Evaluation Assurance Level EEPROM Electrically Erasable Programmable Read Only Memory ETR Evaluation Technical Report IC Integrated Circuit IT Information Technology ITSEF Information Technology Security Evaluation Facility MMU Memory Management Unit OTP One Time Programmable (a certain part of the EEPROM) PP Protection Profile RAM Random Access Memory RNG Random Number Generator ROM Read Only Memory SF Security Function SFP Security Function Policy SOF Strength of Function ST Security Target TOE Target of Evaluation Triple-DES Symmetric block cipher algorithm based on the DES TSC TSF Scope of Control TSF TOE Security Functions TSP TOE Security Policy TSS TOE Summary Specification UART Universal Asynchronus Receiver and Transmitter 19 / 36 Certification Report BSI-DSZ-CC-0583-2009 12.2 Glossary Augmentation - The addition of one or more assurance component(s) from CC Part 3 to an EAL or assurance package.

This conformance result is presented with respect to CC Part 2 (functional requirements), CC Part 3 (assurance requirements) and, if applicable, to a pre-defined set of requirements (e.g., EAL, Protection Profile). The conformance result consists of one of the following: – CC Part 2 conformant - A PP or TOE is CC Part 2 conformant if the functional requirements are based only upon functional components in CC Part 2. – CC Part 2 extended - A PP or TOE is CC Part 2 extended if the functional requirements include functional components not in CC Part 2. plus one of the following: – CC Part 3 conformant - A PP or TOE is CC Part 3 conformant if the assurance requirements are based only upon assurance components in CC Part 3. – CC Part 3 extended - A PP or TOE is CC Part 3 extended if the assurance requirements include assurance requirements not in CC Part 3. Additionally, the conformance result may include a statement made with respect to sets of defined requirements, in which case it consists of one of the following: – Package name Conformant - A PP or TOE is conformant to a pre-defined named functional and/or assurance package (e.g. EAL) if the requirements (functions or assurance) include all components in the packages listed as part of the conformance result. – Package name Augmented - A PP or TOE is an augmentation of a pre-defined named functional and/or assurance package (e.g. EAL) if the requirements (functions or assurance) are a proper superset of all components in the packages listed as part of the conformance result. Finally, the conformance result may also include a statement made with respect to Protection Profiles, in which case it includes the following: – PP Conformant - A TOE meets specific PP(s), which are listed as part of the conformance result.“ 24 / 36 BSI-DSZ-CC-0583-2009 Certification Report CC Part 3: Protection Profile criteria overview (chapter 8.2) “The goal of a PP evaluation is to demonstrate that the PP is complete, consistent, technically sound, and hence suitable for use as a statement of requirements for one or more evaluatable TOEs.

The CC approach identifies the separate concepts of assurance in a TOE at the end of the evaluation, and of maintenance of that assurance during the operational use of the TOE. It is important to note that not all families and components from CC Part 3 are included in the EALs. This is not to say that these do not provide meaningful and desirable assurances. Instead, it is expected that these families and components will be considered for augmentation of an EAL in those PPs and STs for which they provide utility.” Evaluation assurance level (EAL) overview (chapter 11.1) “Table 6 represents a summary of the EALs. The columns represent a hierarchically ordered set of EALs, while the rows represent assurance families. Each number in the resulting matrix identifies a specific assurance component where applicable. As outlined in the next section, seven hierarchically ordered evaluation assurance levels are defined in the CC for the rating of a TOE's assurance. They are hierarchically ordered inasmuch as each EAL represents more assurance than all lower EALs. The increase in assurance from EAL to EAL is accomplished by substitution of a hierarchically higher assurance component from the same assurance family (i.e. increasing rigour, scope, and/or depth) and from the addition of assurance components from other assurance families (i.e. adding new requirements). These EALs consist of an appropriate combination of assurance components as described in chapter 7 of this 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 standard as a valid claim. Augmentation carries with it the obligation on the part of the claimant to justify the utility and added value of the added assurance component to the EAL. An EAL may also be extended with explicitly stated assurance requirements. 27 / 36 Certification Report BSI-DSZ-CC-0583-2009 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: Evaluation assurance level summary” 28 / 36 BSI-DSZ-CC-0583-2009 Certification Report Evaluation assurance level 1 (EAL1) - functionally tested (chapter 11.3) “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 11.4) “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 11.5) “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.” 29 / 36 Certification Report BSI-DSZ-CC-0583-2009 Evaluation assurance level 4 (EAL4) - methodically designed, tested, and reviewed (chapter 11.6) “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 11.7) “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 11.8) “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.” 30 / 36 BSI-DSZ-CC-0583-2009 Certification Report Evaluation assurance level 7 (EAL7) - formally verified design and tested (chapter 11.9) “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.“ Strength of TOE security functions (AVA_SOF) (chapter 19.3) “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 19.4) "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 Independent vulnerability analysis), moderate (for AVA_VLA.3 Moderately resistant) or high (for AVA_VLA.4 Highly resistant) attack potential.” 31 / 36 Certification Report BSI-DSZ-CC-0583-2009 This page is intentionally left blank. 32 / 36 BSI-DSZ-CC-0583-2009 Certification Report D Annexes List of annexes of this certification report Annex A: Security Target provided within a separate document.
