ABSTRACT:
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.
