Introduction
The Certification
Security certification for information technology products and systems is governed by decree
number 2002-535 dated April, 18th 2002, and published in the "Journal Officiel de la
République Française". This decree stipulates that:
• The central information system security department draws up certification reports.
These reports indicate the features of the proposed security targets. They may include
any warnings that the authors feel the need to mention for security reasons. They may
or may not be transmitted to third parties or made public, as the principals desire
(article 7).
• The certificates issued by the Prime Minister certify that the copies of the products or
systems submitted for evaluation fulfil the specified security features. They also
certify that the evaluations have been carried out in compliance with applicable rules
and standards, with the required degrees of skill and impartiality (article 8).
The procedures are available on the Internet site www.ssi.gouv.fr.

2. The evaluation
2.1. Evaluation referential
The evaluation has been performed in compliance with Common Criteria version 2.2 [CC],
and with the Common Evaluation Methodology [CEM].
For assurance components above EAL4 level, the evaluation facility own evaluation methods
consistent with [AIS34] and validated by DCSSI have been used.
In order to meet the specificities of smart cards, the [CCIC] and [CCAP] guides have been
applied.
2.2. Evaluation work
The evaluation has been performed according to the composition scheme as defined in the
guide [COMP] in order to assess that no weakness is introduced from the integration of the
software in the microcontroller already certified.
Therefore, the results of the evaluation of the microcontroller “SLE88CFX4000P” at EAL5
level augmented with ALC_DVS.2, AVA_MSU.3 and AVA_VLA.4, compliant with the
[PP0002] protection profile. This microcontroller has been certified the 23rd
of March 2006
under the reference BSI-DSZ-CC-0269-2006. A maintained version of the product has been
validated through assurance continuity process on the 28th
of March 2007, under the reference
BSI-DSZ-CC-0269-2006-MA-02.
The evaluation technical report [ETR], delivered to DCSSI the 28th
of March 2007, provides
details on the work performed by the evaluation facility and assesses that all evaluation tasks
are “pass”.
2.3. Cryptographic mechanisms robustness analysis
The robustness of cryptographic mechanisms has been analysed by DCSSI. The results are
stated in the cryptographic analysis report [ANA-CRY] and have been taken into account in
the evaluator vulnerability analysis.
The cryptographic analysis showed that key sizes of some of the algorithms don’t reach the
“standard” DCSSI level (see. [REF-CRY]). These limitations are due to the GSM
specification and are not under the developer control. The resulting vulnerabilities are system
relevant and are not specific to the product itself. This is particularly the case for the
authentication service to 2G networks. On the other hand, the authentication service to 3G-
network reaches the DCSSI “standard” level.

Page 11 out 17
2.4. Random number generator analysis
The platform provides two random number generators (a hardware one and software one) that
can be used by the applets developers.
This hardware generator has been evaluated according to AIS31 method in the scope of the
microcontroller certification (see BSI-DSZ-CC-0269-2006). The evaluator has also performed
its own additional analysis. This analysis did not show any flawed statistic bias for a direct
use of the generated numbers. This does not imply that the generated numbers are really
random but ensures that the generator is exempt of major conception flaws. As stated in the
document [REF-CRY], DCSSI reminds that for a cryptographic use, the hardware-generated
numbers shall be reprocessed by a cryptographic algorithm, even if the analysed random
number generator did not show any weakness.
The software random generator consists in a software post-treatment of the random numbers
issued from the hardware generator. This post-treatment doesn’t fulfill DCSSI requirements
for the “standard” level (see [REF-CRY]). For a a cryptographic use, the software generator
shall be reprocessed by a cryptographic algorithm in order to reach the “standard” level.

administrative and GSM/UMTS keys, so they can be used to authenticate the
roles;
- For the Java card:
o No applet loaded post-issuance contains native methods;
o Any byte-code must be verified prior to being loaded, in order to ensure that
each bytecode is valid at execution time.
