摘要: 移动IPv6为IPv6网络提供移动性支持,移动IPv6路由优化消除了移动IP中移动节点和通信对端存在的三角路由问题。但同时,移动IPv6也引入了一些安全上的威胁,其中有很大一部分是关于路由优化中的绑定更新的授权和认证问题。传统的返回可路由机制和CGA生成家乡地址的方法仍然存在安全上的问题,在CAM-DH协议的基础上进行改进,提出了一种新的增强方案,提高了安全性,优化了计算负载和报文交换性能。

Abstract: Mobile IPv6 provides mobility support for the IPv6 Internet.Route optimization eliminates the triangular routing problem existing between the mobile node and correspondent node in mobile IP.However,mobile IPv6 brings some security threats at the same time,a great part of the threats are about the authorization and authentication problem of binding update in route optimization.Some security threats still exist in the return routability protocol and CGA-based protocol,the CAM-DH protocol is improved,a new enhanced protocol is proposed,the security is improved,and the computation and message exchange performance is optimized.
