摘　　要：对接入用户实施认证是移动IPv6实用化的前提.提出一种适用于移动IPv6网络环境的层次化接入认证方法HAMIPv6,对接入认证和移动注册进行层次化管理,利用认证矢量和消息捎带,减少切换认证过程中移动节点与家乡域的交互.HAMIPv6简化了切换认证处理流程,减小了切换延时和信令开销,实现了用户与网络相互认证及会话密钥发放.通过分析比较证明,HAMIPv6比传统方法处理效率更高,尤其是在MN远离家乡域及在一定范围内频繁微移动的情况下.Access authentication is very important for mobile IPv6 networks. In this paper, hierarchical access authentication method in mobile IPv6 （HAMIPv6） is proposed. The method can accomplish access authentication and mobile registration while reducing exchanges between mobile node and home domain by utilizing authentication vector and message piggyback. The method simplifies handoff authentication process by reducing handoff delay and cost. Also the method supports mutual authentication between terminal and network. Performance evaluation shows that the proposed method is better than the others, especially in the conditions that MN is far from home domain and move frequently within a domain.
