基于身份认证的WLAN安全研究

Research on WLAN security based on identity authentication

针对当前传统身份认证算法在安全性上的问题,以及结合WLAN无线网络的特点,根据椭圆曲线算法的优势,提出一种基于椭圆曲线算法的WLAN身份认证。在该认证模式中,通过参数的设置,从而构建加密体系密钥的多样性;通过在有限域上对密钥和公钥的计算,以保证关键信息的安全性,以防止攻击者通过传输对关键信息的获取、篡改等。最后,通过C＋＋语言的编程,验证了上述方案的可行性,从而为我国无线网络安全提供了一种新的借鉴与参考。

In view of the security problems of the current traditional identity authentication algorithm and the characteristics of WLAN wireless network,a WLAN identity authentication based on elliptic curve algorithm is proposed based on the advantages of the elliptic curve algorithm. In the authentication mode,the diversity of the encryption system key is constructed by setting the parameters,and the key and public key are calculated on the limited domain to ensure the security of the key information,so as to prevent the attacker from obtaining and tampering of the key information through transmission. Finally,the feasibility of the above scheme is verified by programming in C ＋ ＋language,thus providing a new reference and reference for China’s wireless network security.
