  Abstract

This paper proposes a fast authentication scheme based on hierarchical key structure (HiFA) for roaming mobile nodes in both intra-domain and inter-domain. The full authentication procedure standardized in IEEE 802.11 and 802.16 is difficult to be applied to a handover since it needs a heavy operation and long delay time during a handover. Though a number of schemes were proposed to solve the problem, the existing schemes might degrade the security of authentication or impose heavy administrative burden on the home authentication server. The main contribution of this paper is to reduce the communication and computation overhead of the home authentication server without degrading the security strength of the fast roaming authentication using hierarchical authentication key structure. The proposed scheme in this paper decentralizes the administrative burden of the home authentication server to other network entities such as a local authentication server or access point and supports the security separation of the authentication key among local authentication servers using hash key chain.
