A hierarchical authentication scheme for M1Pv6 node with local movement property

초록

To reduce the amount of the signaling messages occurred in movement, Hierarchical Mobile IPv6 (HMIPv6) has been introduced as the hierarchical mobility management architecture for MlPv6 by regarding the micro movement. When approaching the visited link, the authentication procedure should be done successfully prior to any mobility support message exchanges. The Authentication, Authorization and Account (AAA) authentication service is applied gradually to the wireless LAN(Local Area Network) and Cellular networks. However, it may bring about the service latency for the sessions of needing the real-time processing due to not providing the optimized signaling in local and frequent movements. In this paper, we propose the authentication architecture with 'delegation' scheme to reduce the amount of signaling message and latency to resume for local movements by integrating it with HMIPv6 architecture. We provide the integrated authentication model and analyze materials comparing to the exiting authentication scheme. It cuts down the cost to 33.6% at average measurement.
