Distribueret informationssystem med automatisk fremkaldelse af nøgleforvaltningsforhandlingsprotokol samt fremgangsmåde

摘要

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 compares the address and security key of a received security protocol data unit to stored end-system addresses and security key information and, in the absence of an existing end-system address and security key, automatically initiates negotiation of a security key between end-systems and then confirms the negotiated security key and initiates a security protocol transmission of the data unit. A method af automatic invoking secure communications between end-systems of a distributed information system is also disclosed.
