Patent

CA 2390239

In a service system distributed as, for example, pay-television, the information exchanged between the operating centre and the user modules uses cryptographic means to guarantee the authenticity and confidentiality of the data. The code processing needs of the operating centre are substantial. For this reason a cryptographic system is proposed that has modularity and security for the cryptographic operations by means of monolithic security units in the form of smart cards.

Dans un système de services distribués tel que la télévision à péage, les information échangées entre un centre de gestion et des modules utilisateurs utilisent des moyens cryptographiques pour garantir l'authenticité et la confidentialité des données. Les besoins en traitment cryptographique dans le centre de gestion sont importants et c'est pourquoi il est proposé un système cryptographique alliant modularité et sécurité par l'utilisation, pour les opérations cryptographiques, d'unités de sécurité monolithique tells que des cartes à puces.
