Revision history	CD21-Rev3

High security features

–Security managed with various access modes: Pin, Session, Always, and Never.

–A cryptographic certificate controls the access to file modifications. The certificate is computed by the reader (using its built-in SAM) and the card during the transaction, using DES, DESX or TDES encryption.

–Calypso automatic recovery mechanism: all data modified in the card during a secure session are either completely done or not done at all.

–Powerful multi-application synchronization capability

–A special mechanism synchronizes modifications between the different applications managed by the card. Each command within the session uses its own secrets or delegates its security to the session security manager.

Memory organization

–Multi-application card

–Data organized in Files according to ISO/IEC 7816-4

–Tele-ticketing compliant with the EN 1545 standard data model

–The file structure may be chosen among many options (for example, 2 Calypso applications, 1 multi-purpose application with 9 contracts and an eTicket application)

–Complete CDLight and CD97 (BX) emulation possible

–Data is protected by diversified keys (up to 6 keys per directory)
