| 摘 要： | 建立完善的身份认证系统是实现网络考试安全的关键步骤之一，而“用户名＋密码”等传统身份认证方式存在较大的安全隐患。文章提出了一种基于MD5和RSA算法的身份认证方案，先利用MD5算法来改进“用户名＋密码”认证方法，再借助MD5和RSA算法实现的数字签名来进一步验证用户的身份。该方案可以高效确认用户身份，极大地增强了考试系统的安全性能。

| Abstract: | Establishing a good identity authentication system is one of the key steps to realize the network examination security, and tradi- tional identity authentication methods like ＂usemame ＋ password＂ have a big security risk. So an identity authentication scheme hased on MD5 and lISA Algorithm is proposed, which uses the MD5 algorithm to improve the ＂usernan~ ＋ password＂ authentication metlmd, and then uses the digital signature based on MD5 and BSA algorithm to further verify the user＇ s identity. This scheme can effectively confirm user identity, and greatly enhance the safety peffonnance of the examination system. |
