摘要: 典型的无线网状网门限认证方案存在客户端执行多次公钥加密使效率较低,不能实现客户端与接入点的双向认证。针对该问题,提出一个防失效的门限认证方案,采用改进的ECDSA签名、门限签名方法进行认证。结果证明,该方案客户端操作次数较少,能实现客户端、接入点与服务器之间的双向认证,有效防止服务器失效。

Abstract: The original scheme can’t achieve mutual authentication between client and AP. Aiming at this problem, this paper analyses one classic threshold authentication scheme for Wireless Mesh Network(WMN) in which the client has to excute asymmetrical encryption causing less efficient. It proposes one compromise-resilient threshold authentication scheme. It adopts improved ECDSA signature, threshold signature. Result shows the clients in this scheme do less operation. It achieves mutual authentication between client, AP and AS. It prevents the server-compromise effectively.

Key words: compromise-resilient, threshold authentication, Wireless Mesh Network(WMN)
