摘要
信息安全的实现首先依赖于对客户端的身份认证。文中提出了利用密钥数据对认证用随机数进行函数变换来实现认证,此函数变换序列具有单向性。指出这种函数变换的典型例子。并对比相关认证理论,给出了安全性分析的结论,即防止重放,和拒否认。
The relization of information security first relys on the identity authentication.The article points out a way of authentication that uses key data to make function tranform on authenticaion-used random data,the function tranform sequence is one-way type.Explain the typical example of the function transform.And comparing to the related authentication theories, the article gets the conclusion of the security analysis：anti replay,non-repudiation.
