ABSTRACT:
Extended authenticated key exchange is described. In one aspect, an identity (IDA) of an initiator and an identity (IDB) of a responder are determined. A first party (i.e., the initiator or the responder) computes a session key based at least on IDAand IDB. A second party (i.e., the initiator or the responder) that is not the first party, uses at least IDAand IDBto compute a corresponding session key. The initiator's session key and the responder's corresponding session key, if equal, provide for secure exchange of data between the initiator and the responder.
