Title
(EN) SMART-CARD BASED ACCESS CONTROL SYSTEM WITH IMPROVED SECURITY
(FR) SYSTEME D'AUTORISATION D'ACCES UTILISANT DES CARTES INTELLIGENTES, A SECURITE AMELIOREE
Abstract
(EN)
A smart card that includes a descrambler for descrambling entitlement information and data provides improved access control by controlling the manner in which the entitlement information portion of the data stream is passed through the smart card. Entitlement data that is descrambled and used in the smart card for functions such as key generation is re-inserted in scrambled form in the high speed output data signal from the smart card. A variable delay device is included in the smart card for controlling when scrambled entitlement data is re-inserted into the data stream. Varying the delay permits establishing a desired timing relationship between the re-inserted data and other data in the data stream that is output from the smart card. For example, scrambled entitlement data in the output data stream can be made to exhibit substantially the same timing relationship to other data that exists in the input data stream.

Une carte intelligente comprenant un dispositif de désembrouillage pour désembrouiller les informations et les données d'autorisation d'accès, améliore le contrôle de l'accès en contrôlant la manière dont la portion d'autorisation d'accès du flux de données passe dans la carte intelligente. Les données d'autorisation d'accès, qui sont désembrouillées et utilisées dans la carte intelligente pour des fonctions telles que la génération de clés, sont réintroduites sous forme embrouillée dans le signal de sortie haute vitesse de la carte intelligente. On prévoit un dispositif à temporisation variable dans la carte intelligente, pour déterminer le moment où les données embrouillées d'autorisation d'accès sont réintroduites dans le flux de données. En modifiant la temporisation, on peut réaliser une relation temporelle souhaitée entre les données réintroduites et d'autres données dans le flux de données sortant de la carte intelligente. Par exemple, on peut faire en sorte que les données d'autorisation d'accès embrouillées, présentes dans le flux de données de sortie, offrent la même relation temporelle avec d'autres données présentes dans le flux de données d'entrée.
