Efficient ID-Based Authenticated Key Agreement

An efficient ID-based authenticated key agreement protocol is proposed in this paper. This protocol provides known key security, perfect forward secrecy, key-compromise impersonation resilience, unknown key-share and imperfect key control. The computational complexity of the proposed protocol is only one elliptic curve point multiplications, one elliptic curve point addition and one operation of the pairing for each party, and the proposed protocol is efficient. The proposed protocol can be extended to address key escrow and key confirmation for application in reality.
