移动IPv6的安全策路是移动IPv6体系的一个重要组成部分。针对现有的移动IPv6安全策略,着重研究通信主 机绑定更新过程的安全性。通过对主机绑定更新过程的分析,指出其存在的安全隐患,并针对移动主机可能 受到拒绝服务攻击的问题提出相应的改进策略,提高通信主机绑定更新过程的安全性。 Mobile IPv6 security policy is an important part of the mobile IPv6 system. In view of the existing mobile IPv6 security policy, the research focuses on the security of the communication host binding update process. According to the analysis of host binding update process, the existing security risks are pointed out. Corresponding improvement strategies are proposed to solve the problem that mobile hosts may be attacked by denial of service, and the security of the host binding update process is improved.
