Leung velung@ece.ubc.ca Received 31 January 2009 Accepted 21 September 2009 Recommended by Yang Xiao The IEEE 802.21 framework for Media Independent Handover MIH provides seamless vertical handover support for multimode mobile terminals. MIH messages are exchanged over various wireless media between mobile terminals and access networks to facilitate seamless handover. This calls for the need to secure MIH messages against network security threats in the wireless medium. In this paper we first analyze IPSec IKEv2 and DTLS security solution for secure MIH message transport. We show that handover latency can be an impediment to the use of IPSec and DTLS solutions. To overcome the handover overhead and hence minimize authentication time a new secure MIH message transport solution referred as MIHSec in this paper is proposed. Experimental results are obtained for MIH between WLAN and Ethernet networks and the impacts of MIH message security on the handover latency are evaluated for IPSec DTLS and MIHSec security solutions. The effectiveness of MIHSec is demonstrated. Copyright 2009 Jeong-Jae Won et al.
