摘要： 以椭圆曲线密码学为基础，通过分析无线局域网的工程环境，选取合适的椭圆曲线参数，构造一种基于椭圆曲线数字签名、三元鉴别的双重签名方案。该方案可以强化对无线局域网中所有实体的鉴别，通信的任何一方都需要得到其他两方的身份验证，从而增强了无线网络环境下对访问控制的安全控制，可以抵制中间人攻击，支持无线网络中的宽带传输。

Abstract: Based on ECC, by analyzing the engineering environment in WLAN and choosing appropriate ECC parameters, this paper describes a dual-signature scheme with tri-element authentication method. The scheme strengthens authentication for all the entities in WLAN. Any party’s identity should be checked by others when associating, so that it can enhance the security of access control in wireless network, restrict man-in-the-middle attack, and support the bandwidth transport in wireless network.

Key words: Elliptic Curve Digital Signature Algorithm(ECDSA), WLAN, man-in-the-middle attack, tri-element authentication
