Patent

CA 2262549

The device generates private key/public key pairs for use with a public key security algorithm. The device includes a security parameter database (12), a control module (101), an operating system (11), a pre-computation device (102), a table T device (103), an online computation device (104), and a public key security algorithm device (13). By the use of precomputation offline, the device reduces the amount of discrete exponentiation with long integers done online.

Cette invention se rapporte à un dispositif qui génère des paires de clés privées et de clés publiques destinées à un algorithme de sécurité à clé publique. Ledit dispositif comporte une base de données de paramètres de sécurité (12), un module de commande (101), un système d'exploitation (11), un organe de précalcul (102), une table T (103), un organe de calcul en ligne (104), et un algorithme de sécurité à clé publique (13). Grâce au calcul effectué hors-ligne, le dispositif réduit la quantité d'exponentiations discrètes effectuées en ligne avec des entiers longs.
