网络安全与身份认证技术的研究与实现

摘要
身份认证就是证实用户真实身份与其所声称的身份是否相符，以防止非法用户通过身份欺诈访问系统资源的过程。一次性口令身份认证技术安全性高、使用方便、管理简单、成本便宜，具有广泛的应用前景。一次性口令就是在登录过程中加入不确定因素，使每次登录传送的认证信息都不相同，以提高登录过程安全性。本文设计了一个一次性口令身份认证系统，对网络结构工作流程密码算法等进行了详细论述。

Abstract
Identity authentication is a process that is used to approve whether the true identity of user is matched to the identity which the user claims, so that the illegal user can not access the system resource by identity cheat. One time password has good application future because it is secure, convenience in use, simple managed and cheaper cost. By adding uncertain factors to entering course, one time password makes authentication information dynamically at every time, so as to improve the security. A one time password identity authentication system is designed in this paper.
