Two-party certificateless authenticated key agreement (CL-AKA) protocol is a hot topic in the field of wireless communication security.An improved two-party CL-AKA protocol with enhanced security is proposed,which is of provable security and unforgeability in the extended Canetti-Krawczyk (eCK) security model based on the hardness assumption of the computational Diffie Hellman (CDH) problem.Compared with other similar protocols,it is more efficient and can satisfy security properties such as free of the centralized management of certificate and key,free of bilinear pairings,two-party authentication,resistant to unknown key-share attack,key compromise impersonation attacks,the man-in-the-middle-attack (MIMA) of key generation center (KGC),etc.These properties make the proposed protocol have better performance and adaptability for military communication.
