Abstract
Almost all the existing identity-based key agreement (ID-KA) protocols cannot achieve both ephemeral secret reveal resilience and pairing-free. In this paper, a pairing-free ID-KA protocol is proposed, which captures all basic desirable security properties including key generation center forward secrecy, key compromise impersonation resilience and ephemeral secrets reveal resistance. On the other hand, the proposed scheme only needs one round communication between the two parties. Compared with the previous ID-KA protocols, the proposed scheme is more secure and efficient.
