The rapid proliferation of mobile networks has made security an important issue, particularly for transaction oriented applications. Recently, Jo et al. presented an efficient authentication protocol for wireless mobile networks and asserted that their proposed approach provides all known security functionalities including session key (SK) security under the assumption of the widely-accepted Canetti–Krawczyk (CK) model. We reviewed Jo et al.’s proposed roaming protocol and we demonstrate that it fails to provide the SK-security under the CK-adversary setting. We then propose an enhancement to Jo et al.’s roaming protocol to address the security drawback found in Jo et al.’s protocol. In the enhanced roaming protocol, we achieve the SK-security along with reduced computation, communication and storage costs. We also simulate the enhanced roaming protocol using NS2 for end-to-end delay and network throughput, and the simulation results obtained demonstrate the efficiency of our protocol.
