Executive Summary
The Target of Evaluation (TOE) is the Renesas HD65256D1 version 02 smartcard
integrated circuit manufactured in Naka (Japan), see chap. 2. The HD65256D1 version 02
is an integrated circuit (IC) providing a hardware platform to a smart card operating system
and smart card application software.
The TOE is intended for use in a range of high security applications, including high speed
security authentication, data encryption or electronic signature. Several security features
independently implemented in hardware or controlled by software will be provided to
ensure proper operation and integrity and confidentiality of stored data. This includes for
example measures for memory protection, leakage protection and sensors to allow
operations only under specified conditions.
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, July 2001,
Eurosmart, 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 4
augmented by ADV_IMP.2, ALC_DVS.2, AVA_MSU.3 and AVA_VLA.4.
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 Security Functional Requirements (SFR) relevant for the IT-Environment of the TOE
are outlined in the Security Target [6] and [9], chapter 5.1.
The TOE Security Functional Requirements are implemented by the following TOE

The version number is indicated in EEPROM address H'100000. The value for this TOE is
“02”. The chip manufacturer site code is indicated in address H'100001. The value for this
TOE is “10” for Naka.
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 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), 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 functions
(security mechanisms and associated functions) provided by the TOE.
4
Assumptions and Clarification of Scope
The Assumptions defined in the Security Target and some aspects of Threats and
Organisational Security Policies are not covered by the TOE itself. These aspects lead to
specific Security Objectives to be fulfilled by the TOE-Environment. The following topics
are of relevance:
●
Protection during Packaging, Finishing and Personalisation
●
Usage of Hardware Platform
●
Treatment of User Data
●
Usage of Key-dependent Functions
●
Injected Data Support
Details can be found in the Security Target [6] and [9] chapter 3.2.

Architectural Information
The Renesas HD65256D1 smartcard integrated circuit version 02 is an integrated circuit
(IC) providing a hardware platform to a smart card operating system and smart card
application software. The top level block diagram and a list of subsystems can be found
within the TOE description of the Security Target. The complete hardware description and
the complete instruction set of the Renesas HD65256D1 smartcard integrated circuit
version 02 is to be found in the Hardware Manual [11].
14 / 34
BSI-DSZ-CC-0529-2010
Certification Report
For the implementation of the TOE Security Functions basically the components AE-5
Series CPU, EEPROM, System Control Registers, DES coprocessor, Firewall
Management Unit, a Random Number Generator, the analog block with security sensors
and the random logic module for security logic are used. Security measures for physical
protection are realized within the layout of the whole circuitry.
The TOE IC Dedicated Software, 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 evaluated documentation as outlined in table 2 is being provided with the product to
the customer. This documentation contains the required information for secure usage of
the TOE in accordance with the Security Target.
Additional obligations and notes for secure usage of the TOE as outlined in chapter 10 of
this report have to be followed.
7
IT Product Testing
The tests performed by the developer were divided into four categories:
●
tests which are performed in a simulation environment,
●
functional production tests, which are done as a last step of the production process
(phase 3) and additionally done as a last step of IC Packaging. These tests are done
for every chip to check its correct functionality,
●
characterization tests, which were used to determine the behaviour of the chip with
respect to different operating conditions and
●
special verification tests for security functions which were done with samples of the
TOE.
The developer tests cover all security functions and all security mechanisms as identified
in the functional specification and the high level design. Chips from the production site in
Naka were used for tests (see annex A of this report).
The evaluators repeated the tests of the developer either using the library of programs and
tools 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 by
sampling. Besides repeating exactly the developers tests, test parameters were 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.
The evaluators gave evidence that the actual version of the TOE (version 02 with IC
manufacturer's ID number ‘10‘ for Naka) provides the security functions as specified. 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 performed to consider the physical tampering of the TOE
using highly sophisticated equipment and expert know how.

BSI-DSZ-CC-0529-2010
Evaluated Configuration
The TOE is identified by Renesas HD65256D1 version 02 and the IC manufacturer’s ID
number ‘10‘ for Naka. This is the only evaluated configuration of the TOE. 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.

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).
The following guidance specific for the technology was used:
●
Supporting Document – Mandatory Technical Document, The Application of CC to
Integrated Circuits
●
Supporting Document – Mandatory Technical Document, Application of Attack Potential
to Smartcards
●
Functionality classes and evaluation methodology for true (physical) random number
generators
●
Supporting Document - Guidance, Smartcard Evaluation
(see [4], AIS 25, AIS 26, AIS31, AIS37) 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 4 package as defined in the CC (see also part C of this
report)
●
The components ADV_IMP.2, ALC_DVS.2, AVA_MSU.3 and AVA_VLA.4 augmented for
this TOE evaluation.
As the evaluation work performed for this certification procedure was carried out as a reevaluation based on the certificate BSI-DSZ-CC-0434-2007. All evaluation evidence is
assessed although some part of the evaluation evidence is similar or even the same. Reuse of results from site visits performed by T-Systems is applied.
The evaluation has confirmed:

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 9, Para. 4, Clause 2). This holds for:
●
The TOE Security Function SF.DES (DES Coprocessor)
The strength of the cryptographic algorithms was not rated in the course of the product
certification (see BSIG Section 4, Para. 3, Clause 2). But Cryptographic Functionalities
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 Functionality DES provided by the TOE achieves a security level of
lower than 80 Bits (in general context).
10 Obligations and Notes for the Usage of the TOE
The operational documents as outlined in table 2 contain necessary information about the
usage of the TOE and all security hints therein have to be considered.
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])

C Excerpts from the Criteria
CC Part1:
Conformance results (chapter 7.4)
„The conformance result indicates the source of the collection of requirements that is met
by a TOE or PP that passes its evaluation. 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.“

Evaluation assurance levels (chapter 11)
“The Evaluation Assurance Levels (EALs) provide an increasing scale that balances the
level of assurance obtained with the cost and feasibility of acquiring that degree of
assurance. 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.

Certification Report
BSI-DSZ-CC-0529-2010
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.”
28 / 34
BSI-DSZ-CC-0529-2010
Certification Report
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.”
29 / 34
Certification Report
BSI-DSZ-CC-0529-2010
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.”
