摘　　要：无线通信中存在移动设备宽带不稳定和存储容量少的问题,802.1X认证、VPN认证、PKI认证等方式无法满足客户端接入企业网络过程中无线通信身份认证的安全问题,提出了一种基于组合公钥(CPK)的无线身份认证方案.首先,提出的改进方案是基于原椭圆曲线上对密钥协商协议进行的改进,实现在无线网络下安全通信;然后,研究在该协议下基于组合公钥登录认证的实现过程,基于组合公钥的认证技术支持客户端的访问;最后,对改进的方案进行安全性分析.通过模拟实验对比,证明基于组合公钥的无线身份认证方案有较强的安全性并缩短了认证的时间.Due to the limitation of the broadband and storage of mobile devices,802.1X authentication,VPN authentication and PKI authentication can not meet the requirements of wireless communication authentication in the process of client access to enterprise network.A CPK-based wireless authentication scheme is proposed.Firstly,the improved scheme is based on the original elliptic curve,which improves the key agreement protocol and realizes the communication in wireless network.Then,the implementation process of CPK-based login authentication under this protocol is studied to support client access.Finally,the security of the improved scheme is analyzed.The simulation results show that the scheme based on CPK has strong security and computational efficiency.
