摘　　要：在基于IEEE802.1x的无线局域网中,所有站点只能和接入点直接通信,从而导致无线局域网的吞吐率较低,接入点运算负荷过大。针对这一问题,文章提出将改进的消息可恢复Rabin-PSS概率签名算法和El-Gamal签名算法相结合,采用非对称认证的方式进行无线局域网接入认证,减轻接入点的运算负荷。同时,Rabin-PSS概率签名算法具有消息可恢复功能,可节省通信的带宽。In the wireless local area network based on IEEE802.1x,all stations can only communicate with the access point,which causes some problems such as low throughput efficiency,heavy load of operation.In order to resolve these problems,a new authentication method is proposed based on the ElGamal digital signature algorithm and the improved Rabin-PSS digital signature algorithm.By asymmetric authentication,this method releases the pressure of the access point.And the Rabin-PSS digital signature algorithm has the function of message recovery and saves the communication bandwidth.
