Abstract

Cette invention porte sur une structure de protection cryptographique pouvant être utilisée dans la cryptographie et dans la micro-électronique afin, d'une part, de garantir la confidentialité lors de transactions financières ou de négociations confidentielles, et d'autre part de protéger des programmes informatiques contre toute reproduction non autorisée. Les systèmes de chiffrement sont fondés sur un code commun unique de chiffrement et de déchiffrement d'informations assurant la sécurité cryptographique maximale. Cette structure de protection cryptographique individuelle se compose d'une « crafe-cassette » pourvue d'un circuit intégré micro-électronique sur lequel un « cliché électronique » est enregistré, lequel cliché comprend un « crafe-code », une unité de contrôle de fonctionnement, une unité de contrôle de l'intégralité de l'enveloppe de protection de la « crafe-cassette » ainsi qu'une horloge incorporée. Ce « crafe-code » se compose d'un code-mère enregistré dans une mémoire volatile de type CMOS, d'une unité de conversion de code, d'une unité de synchronisation de conversion et d'un générateur de nombres aléatoires. Cette structure est également pourvue d'un « crafe-bracelet » comportant un guide spécial servant à identifier un utilisateur et de divers terminaux permettant à l'utilisateur d'exécuter des opérations à l'aide de cette structure. Le terminal peut se présenter sous la forme d'un dispositif quelconque, pourvu d'un port de branchement de cette « crafe-cassette », de dispositifs entrée-sortie d'informations, d'une source d'énergie ainsi que d'un port de branchement de guide de « crafe-bracelet ».
