The design of simple cryptographic protocols for elementary two-party (session oriented) tasks (such as entity authentication and key transport) has had a history (starting with [NS78]) where security has been quite evasive. Only recently we have seen protocol designs which are both provably secure and efficient Currently, much attention of the designers of network systems and services is directed towards group operations, which will enable such important tasks as one-to-many distribution of… CONTINUE READING
