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 p rocessed (20, 24) to automatically initiate negotiation of a security key between end-sys tems (A, B) and then confirms the negotiated security key and initiates a security pr otocol transmission of the data unit using transmitters and receivers (18, 20) and prot ocol processors (19, 28). |
