Abstract
Extended authenticated key exchange with key confirmation is described. In one aspect, and before computing session keys to exchange information securely between an initiator and a responder, each party of the initiator and the responder, confirms whether the other party has received corresponding information to generate a valid session key. If either party determines that the other respective party has not received the corresponding information, the party terminates the extended authenticated key exchange with key confirmation protocol. Otherwise, when a party determines that the other party has received the corresponding information, the party generates a respective session key. In this manner, when both parties confirm that the other party has received the appropriate information for session key generation, both parties are assured that information can be exchanged between the parties securely using the session keys.
