摘　　要：在分析现有无线网络安全性的基础上,提出利用视觉密码技术提高无线网络远程身份认证安全性的方法。以一张图像作为母图,并将母图信息分散的隐藏在多个子图中。利用伪随机数发生器与原始公钥产生新的公钥,从而使得母图具有一次一密的特点,同时采用密钥组关联保证通信的同步性。Based on comprehensive analysis about current security mechanisms of wireless network, a new way was put forward, which introduced visual cryptography to enhance the security of tele-identity authentication for wireless network. To ensure the confidentiality of master graph in Visual Cryptography System （VCS）, master graph was replaced by public key termly, and the new public key was replaced by combining pseudo-random number generator with the original public key. Thus, the master graph has the characteristic of one-time-pad. Meanwhile, different key sets were adopted to ensure the synchronization of communication between server and customer. The proposed scheme is convenient, low-cost, rapid and secure.
