HMIPv6技术能够实现无线Mesh网络的无缝切换,针对其绑定更新过程中执行路由优化存在的安全问题,提出了一种适用于无线Mesh网络的基于椭圆曲线公钥自认证体制的安全路由优化方案.该方案使用户在执行路由优化的过程中能够实现对绑定更新消息的认证与授权,且通过有效的会话密钥协商机制为绑定更新消息的传输提供了安全保障,具有可证明安全性.最后通过性能分析表明,该方案简化了标准路由优化方案的流程,提高了一般注册过程的效率.%HMIPv6 technology can implement the seamless handover in wireless mesh network. To address the security issues of route optimization in the mobile handover binding update procedure,a elliptic curve cryptography self-certified public key cryptosystem based secure route optimization scheme was proposed, which is applicable to the wireless mesh network. The proposed scheme not only addresses authentication and authorization of binding update messages in route optimization for mesh clients, but also provides security for the binding update messages by effective session-key negotiation mechanism, which affords provable security. Furthermore, the performance analysis shows that the proposed scheme can simplify the procedure of standard routing optimization scheme and improve the efficiency of the general registration procedure.
