Secure Access Authentication for Media Independent Information Service
To optimize vertical handover in heterogeneous networks, IEEE 802.21 standard defines Media Independent Handover (MIH) services. The MIH services can be a new target to attackers, which will be the main concerns for equipment vendors and service providers. In this paper, the authors focus specifically on security of Media Independent Information Service (MIIS), and present a new access authentication scheme for MIIS based on Kerberos. Security and performance of the protocol are also analyzed in this paper. Recent advances in wireless communication technologies have resulted in the evolution of various wireless networks, such as cellular network, wireless local area network, ad hoc network, personal communications networks.
