Patent

CA 2054731

The invention is an improved distributed information system which automatically provides for the transmission of security protocol data units between end-users of a distributed information system. The invention includes a processor (14) that compares the address and security key of a received security protocol data unit to stored end-system addresses and security key information stored in memory (10, 12) and, in the absence of an existing end-system (B) address and security key, includes a processed (20, 24) to automatically initiate negotiation of a security key between end-systems (A, B) and then confirms the negotiated security key and initiates a security protocol transmission of the data unit using transmitters and receivers (18, 20) and protocol processors (19, 28).

L'invention est un système d'information réparti amélioré qui transmet automatiquement des unités de donnée de protocole de sécurité entre ses utilisateurs. Le système de l'invention comprend un processeur (14) qui compare l'adresse et la clé de sécurité d'une unité de donnée de protocole de sécurité reçue avec des adresses et des clés de sécurité de système terminal stockées dans une mémoire (10, 12) et, en l'absence d'une adresse et d'une clé de sécurité d'un système terminal existant (B), utilise un processeur (20, 24) pour amorcer automatiquement la négociation d'une clé de sécurité entre des systèmes terminaux (A, B), puis confirme l'acceptation de la clé de sécurité négociée et amorce la transmission de l'unité de donnée selon le protocole de sécurité en utilisant des émetteurs et des récepteurs (18, 20) et des processeurs à protocole (19, 28).
