Abstract: HMIPv6 technology can implement the seamless handover in wireless mesh network. ho 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. hhe 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 negotianon 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.
