摘　　要：移动IPv6支持路由优化模式,实现了移动节点和通信节点直接通信,提高了效率。然而该模式没有真正实现通信双方的身份认证,存在伪造攻击的可能,而且不适合在大规模网络环境下使用。本文针对此问题提出一种基于HIBE的改进方案,并从安全性以及执行效率方面与现有的方式进行了分析和比较。该方案充分利用HIBE机制和移动代理的特点,保证了通信双方的相互认证,实现了移动节点同时到多个通信节点的注册,不仅提高了移动IPv6的安全性,而且效率更高。Mobile Node and Correspondent Node can communicate directly in Mobile IPv6 routability optimization, so communications efficiency is improved. However, the two nodes haven＇t really carried out identity authentication which is most likely attacked by fake nodes, and can not be employed in a large scale of network. To solve the above problem, this paper proposes an improved scheme based on HIBE. We analyzed compared the proposed scheme with current one in terms of security and executive efficiency, and the results show that, the new scheme makes the best use of HIBE and mobile agent, guarantee the identity authentication of nodes, and realized the registration of mobile node to multi correspondent nodes synchronously. The new scheme improves mobile IPv6 security and the efficiency as well.
