摘　　要：随着科技的不断发展,越来越多的网络设备接入到无线网络中,为了确保合法用户的正确识别连接,在WenLi认证方案的基础上提出了一种基于Hash函数的无线双向安全认证方案。该方案通过引入发送包序列号代替时间戳,避免网络延时对认证过程产生影响,且不需要设备之间时钟的严格同步。安全性与运算量的对比分析表明,较Wen-Li方案,所提方案能有效避免各种常见的网络攻击,具有更高的安全性,且运算量较小,计算复杂度较低,能有效降低实际系统的开销。With the development of science and technology,more and more network devices are connected to the wireless network.In order to ensure the legitimate users＇ correct identification and connections,based on the Wen-Li authentication scheme,a novel two-way security authentication wireless scheme based on hash function（TSAWSH）was proposed.By using the send packet sequence number instead of of timestamp,the TSAWSH can avoid the influence to the certification process caused by the network delay and needn＇t the strict clock synchronization between the devices.By comparing the security and complexity analyses with the Wen-Li scheme,the TSAWSH can effectively avoid the common network attacks,has higher safe property and less computational quantity,and also has lower computational complexity.The TSAWSH can effectively reduce the overhead of the actual system.
