Seamless handover across different access technologies is very important in the future wireless networks. 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 concern for equipment vendors and service providers. In this paper we focus specifically on security of Media Independent Information Service MIIS and present a new access authentication scheme with user anonymity for MIIS. The protocol can be used to establish a secure channel between the mobile node and the information server. Security and performance of the protocol are also analyzed in this paper. 1. Introduction 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 communication network Communication in next generation networks will use multiple access technologies creating a .
