Abstract
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.
Highlights
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 generation networks will use multiple access technologies, creating a heterogeneous network environment [1]
The IEEE 802.21 standard aims at optimizing handovers among heterogeneous wireless networks
We propose an anonymous access authentication protocol for Media Independent Information Service (MIIS) defined in the 802.21 standard
Summary
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 generation networks will use multiple access technologies, creating a heterogeneous network environment [1]. During the handover execution phase, the connections need to be rerouted from the existing network to the new network in a seamless manner This phase includes the authentication and authorization, and the transfer of user’s context information. Recent efforts by the IEEE 802.21 working group have designed a framework [15] to facilitate handover between heterogeneous networks by providing mobile users with information useful for making handover decisions. The task of the group is [17]: (i) to reduce the latency during authentication and key establishment for handovers between heterogeneous access networks that support IEEE 802.21 (ii) to provide data integrity, confidentiality, replay protection, and data origin authentication to MIH protocol exchanges and enable authorization for MIH services.
