Most available Identity-based Authenticated Key agreement (ID-AK) protocols require expensive bilinear pairing operation. This paper proposes a pairing-free ID-AK protocol from additive elliptic curve group. The new protocol eliminates the pairing operations, and reduces overall computation time by at least 33.3 percent compared with previous ID-AK protocols. The new protocol also satisfies master key forward secrecy, perfect forward secrecy and key compromise impersonation resilience. The security of the proposed protocol can be reduced to the standard Computational Diffie-Hellman assumption in the random oracle model.
