用户身份认证技术在计算机信息安全中的应用

Application of User Identity Authentication Technology in Computer in Information Security

用户身份认证是安全的第一道大门,是各种安全措施可以发挥作用的前提。在计算机信息安全领域中,身份认证是一门重要课程。通过概述信息用户身份认证技术在学校数字校园网络中的应用,阐述了身份认证系统的设计目标,提出了身份认证系统要能以多种方式加以运用,然后对基于PHP的互联网身份认证系统的原理及实现进行了分析,对动态口令用户身份验证流程进行了研究。最后,对依托图片动态验证码实现身份认证和应用MD5算法实现身份验证方法进行了举例分析。

The user identity authentication is the first gate security, is the premise of various security measures can play a role. In the field of computer information security, identity authentication is an important course. Through the application of information the user identity authentication technology in the digital campus network, expounds the design target identity authentication system. This paper presents the identity authentication system to be used in a variety of ways. Based on the principle of Intamet authentication system of PHP and its implementation is analyzed based on the dynamic password, the user authentication process were studied. Finally, this paper studies the dynamic verification code to achieve authentication. The article also analyzes the realization of authentication based on MD5 algorithm.
