ABSTRACT:
A method for authenticating nodes/users and in protecting data flow between nodes. This is facilitated by creating a dialogue involving authenticated encryption among the nodes. During each session, a key for use in cryptographic conversion is constructed among the node participants in order to permit symmetric authentication. The key is unique to the session. A different key is generated for each and every session. The building of the session key involves sharing of a minimal amount of information among the participants in the form of combining both a random number and authentication indicia.
