Abstract

Un dispositif semi-conducteur sert de clé (12) d'accès à un ordinateur (34) ou à un programme contenu dans un ordinateur et assure la sécurité de communications. Le dispositif (64) met en exécution un algorythme qui combine une racine et une valeur de départ pour produire un mot de passe. Le mot de passe est entré dans l'ordinateur (34). L'ordinateur (34) utilise un algorythme équivalent pour produire un mot de passe à l'intérieur de l'ordinateur (34). La comparaison ou d'autres procédés sont utilisés pour donner accès à l'ordinateur (34) ou au programme de l'ordinateur ou pour assurer la sécurité de communications. L'ordinateur (34) peut être codé de manière à produire sur un écran vidéo (18) un motif temporel-spatial de stimulation qui peut être reçu par des détecteurs (28a-28d) de la clé. Alternativement, un clavier (700) peut être utilisé pour transférer le stimulus sortant de l'ordinateur (34, 68) à la clé d'accès (12). Le présent système assure en outre la sécurité de communications grâce à l'utilisation d'algorythmes entre des ordinateurs divers et entre des endroits éloignés les uns des autres.
