The Cortex-M33 CPU architecture of the SP of S3B512C microcontroller follows the Harvard style,
that is, it has separate program memory and data memory. Both instruction and data can be
fetched simultaneously without causing a stall, using separate paths for memory access.
The main security features of the SP of S3B512C integrated circuit are:
• Secure fingerprint image capture and feature extraction provided by TOE SP firmware,
integrity protected.
• Access control of Users to Flash memory positions where SP firmware is executed.
• TOE Unique Identification
• Countermeasures to avoid attackers reproduction of fingerprint data.
• An AES hardware block supporting AES encryption and decryption with 128-bit, 192-bit and
256-bit keys in ECB mode. The AES block supports encryption of fingerprint features to be
sent to SE of S3B512C.
The TOE is dedicated to application as within the context of banking and finance applications for
credit or debit cards electronic purse (stored value cards) and electronic commerce, where the
biometric fingerprint identification is a cardholder’s authentication method, the TOE is intended to
acquire the fingerprint image of the cardholder, process it and pass the fingerprint extracted
features to the Secure Element.
Note SE (Secure Element) is not TOE.

ASSUMPTIONS AND OPERATIONAL ENVIRONMENT
The following assumptions are constraints to the conditions used to assure the security properties
and functionalities compiled by the security target. These assumptions have been applied during
the evaluation in order to determine if the identified vulnerabilities can be exploited.
In order to assure the secure use of the TOE, it is necessary to start from these assumptions for its
operational environment. If this is not possible and any of them could not be assumed, it would not
be possible to assure the secure operation of the TOE.

RECOGNITION AGREEMENTS
In order to avoid multiple certification of the same product in different countries a mutual
recognition of IT security certificates - as far as such certificates are based on ITSEC or CC - under
certain conditions was agreed.
European Recognition of ITSEC/CC – Certificates (SOGIS-MRA)
The SOGIS-Mutual Recognition Agreement (SOGIS-MRA) Version 3 became effective in April 2010. It
defines the recognition of certificates for IT-Products at a basic recognition level and, in addition, at
higher recognition levels for IT-Products related to certain SOGIS Technical Domains only.
The basic recognition level includes Common Criteria (CC) Evaluation Assurance Levels EAL 1 to EAL
4 and ITSEC Evaluation Assurance Levels E1 to E3 (basic). For "Smartcards and similar devices" a
SOGIS Technical Domain is in place. For "HW Devices with Security Boxes" a SOGIS Technical
Domains is in place, too. In addition, certificates issued for Protection Profiles based on Common
Criteria are part of the recognition agreement.
The new agreement has been signed by the national bodies of Austria, Finland, France, Germany,
Italy, The Netherlands, Norway, Spain, Sweden and the United Kingdom. The current list of
signatory nations and approved certification schemes, details on recognition, and the history of the
agreement can be seen on the website at https://www.sogis.eu.
The SOGIS-MRA logo printed on the certificate indicates that it is recognised under the terms of this
agreement by the nations listed above.
The certificate of this TOE is recognized under SOGIS-MRA for all assurance components selected.
International Recognition of CC – Certificates (CCRA)
The international arrangement on the mutual recognition of certificates based on the CC (Common
Criteria Recognition Arrangement, CCRA-2014) has been ratified on 08 September 2014. It covers
CC certificates based on collaborative Protection Profiles (cPP) (exact use), CC certificates based on
assurance components up to and including EAL 2 or the assurance family Flaw Remediation
(ALC_FLR) and CC certificates for Protection Profiles and for collaborative Protection Profiles (cPP).
The CCRA-2014 replaces the old CCRA signed in May 2000 (CCRA-2000). Certificates based on CCRA-
2000, issued before 08 September 2014 are still under recognition according to the rules of CCRA-
2000. For on 08 September 2014 ongoing certification procedures and for Assurance Continuity
(maintenance and re-certification)of old certificates a transition period on the recognition of
certificates according to the rules of CCRA-2000 (i.e. assurance components up to and including EAL
4 or the assurance family Flaw Remediation (ALC_FLR)) is defined until 08 September 2017.
13/13

organismo.certificacion@cni.es
As of September 2014 the signatories of the new CCRA-2014 are government representatives from
the following nations: Australia, Austria, Canada, Czech Republic, Denmark, Finland, France,
Germany, Greece, Hungary, India, Israel, Italy, Japan, Malaysia, The Netherlands, New Zealand,
Norway, Pakistan, Republic of Korea, Singapore, Spain, Sweden, Turkey, United Kingdom, and the
United States.
The current list of signatory nations and approved certification schemes can be seen on the
website: http://www.commoncriteriaportal.org.
The Common Criteria Recognition Arrangement logo printed on the certificate indicates that this
certification is recognised under the terms of this agreement by the nations listed above.
The certificate of this TOE is recognized under CCRA for all assurance components selected.
