Fast Handover with Privacy Preserving Authentication Protocol for Mobile WiMAX Networks

Abstract

In this paper, we propose new fast handover authentication scheme with privacy preservation to improve the capabilities of IEEE 802.16m network. New metric is presented for handover authentication protocols in wireless networks. It’s the required time for base station and mobile station to detect the undesirable messages. We propose a new scheme which gives a minimum time of detection to these fault and undesirable messages. Our protocol uses symmetric encryption which gives a good level of secrecy. The identity of the mobile station (MS) is changed for every hop which preserves privacy. Numerical analysis results show that our protocol is better than IEEE 802.11 m authentication in authentication delay parameter.
