Abstract: A microprocessor configuration includes a data bus for data transfer between functional units. On the bus side, each unit contains an encryption/decryption unit that is controlled synchronously by a random number generator. The configuration permits a relatively high level of security against monitoring of the data transferred via the data bus, with a feasible level of additional circuit complexity.

Abstract: Un dispositif de communication 100 pour transmettre des données à un dispositif de partenaire de communication 200 présente un dispositif d'émission 102 destiné à envoyer des données d'émission 112 au dispositif de partenaire de communication 200. Le dispositif de communication 100 présente, par ailleurs, un dispositif de détermination destiné à déterminer une valeur de contrôle 114, selon une prescription de détermination, à partir des données d'émission et un dispositif de réception 108 du dispositif de communication 100 reçoit une valeur de vérification 116 du dispositif de partenaire de communication 200 et un dispositif de contrôle 106 du dispositif de communication 100 est réalisé de manière à comparer la valeur de contrôle 114 avec la valeur de vérification 116 et à préparer un signal d'indication d'erreur 118 en fonction de la comparaison.

Abstract: A shift device for shifting a first place of a data word, which consists of a plurality of places, to a second place so as to obtain a shifted data word, wherein the first place is encrypted using a first encryption parameter and wherein the second place is encrypted using a second encryption parameter, includes a unit for shifting the first place of the data word to the second place of the data word, a unit for re-encrypting the first place from an encryption using the first encryption parameter into an encryption using the second encryption parameter, and a control for controlling the unit for shifting and the unit for re-encryption so that the first place is first shifted to the second place and is then re-encrypted, or that the first place is first re-encrypted and is then shifted to the second place. This ensures that data encrypted either with the first encryption parameter or with the second encryption parameter are always shifted, thus making it harder for attackers to eavesdrop on clear text data.
