Abstract
A protocol for use as a phase 1 authentication (and key agreement) IKE protocol, similar to IKE phase 1 authentication with public key encryption, but using the IMS AKA trust infrastructure instead of the PKI trust infrastructure. The invention thus allows an initiator () having a secret long-term key stored on a smart cart (), to authenticate a responder (), the responder () having in some cases a trusted interface with a Home Subscriber Server () that has a copy () of the initiator's long-term key (and in other cases having itself access to the initiator's long-term key). The protocol includes a Diffie-Hellman exchange, and by authenticating the initiator () and responder (), the protocol authenticates the exchange.
