Abstract

Instrument de sécurisation pour le chiffrement/déchiffrement de messages échangés entre chacun des acteurs d'un réseau d'une pluralité d'acteurs, pouvant chacun agir comme émetteur ou destinataire d'un message crypté ou scellé, caractérisé en ce qu'il comprend pour chaque acteur un dispositif (E1) comportant un circuit intégré avec des zones de mémoire (2, 3), un microprocesseur (1) capable d'exécuter un algorithme et de contrôler l'accès à ces zones (2, 3) en fonction de la nature de l'opération demandée au microprocesseur par l'opérateur qui détient le dispositif et choisie par les opérations de chiffrement (6, 7), de calcul d'une clé à communiquer (8) et de déchiffrement (9, 10), les zones de mémoire (2 et 3) contenant deux types de clés de base masquées dont une clé de base (T1) du premier type est propre à chaque dispositif (E1) et dont au moins une clé de base (U2) du second type est commune à tous les dispositifs.
