Abstract

In this paper, we propose local authentication scheme to locally authorize intra-domain mobile nodes (MNs) for efficient authentication in Mobile IPv6 networks, which are based on authentication, authorization, accounting (AAA) architecture. Frequent authentication requests in standard AAA mechanism impose a great burden to deliver the authentication messages between a MN and its AAA server. To solve this problem, we propose this scheme to establish local security associations (SAs) for authentication, so the proposed scheme reduces delay and the risk during MNs roam around a local domain. The performance evaluation results show that the proposed scheme reduces the latency up to 60.7% while maintaining the similar level of security to the previous researches.
