| Summary: | The fast development of mobile networks and compact mobile devices bring attention to the users for wireless mobile communication. But providing security and protecting the privacy of users are the main challenges of wireless mobile communication. Recently, Authenticated Key Agreement protocols are used for secure and reliable communication in wireless mobile communication. However, the User-to-User Mutual Authentication and Key Agreement scheme is based on bilinear pairings, which involves relatively high computation cost when compared to elliptic curve scalar point multiplication. Hence, in this paper, we propose a Pairing-Free Identity-Based Mutual Authentication and Key Agreement protocol for wireless mobile communications. It consists of the following phases: Setup and Key generation, Mobility Management Entity authentication and Proxy Signature generation, Proxy Signature verification and User-to-User authentication. Experimental results show that Pairing-Free Identity-Based Mutual Authentication and Key Agreement attains significantly less computational and communication cost when compared to User-to-User Mutual Authentication and Key Agreement scheme.
