Authentication mechanism for network mobility based on local security associations
基于本地安全关联的移动网络接入认证机制

In order to reduce the impact of identity authentication on performance of network mobility, this paper introduced an authentication mechanism. In the mechanism, integrated the authentication and binding update procedures by adding address registration information into authentication messages. With the help of local mobility management strategy and local security associations, the mechanism localized the message flow of the intra-domain handoff, protected the address registration information and eliminated the tunnel-in-tunnel problem. Analysis shows that, the mechanism not only implements the mutual authentication but also resists various attacks such as modified attack. The proposed solution outperforms the counterparts in terms of the computation cost and handoff latency.
