基于MD5算法和Schnorr协议的双因素身份认证系统

Double-factor System of Identity Authentication Based onMD5 Algorithm and Schnorr Protocol

身份认证就是通过某种手段对用户所声称的身份进行认证的过程,它是实现系统安全的重要机制。将静态口令机制和动态口令机制结合起来,提出了一个双因素身份认证方案,静态口令用安全的散列函数MD5算法加密,动态口令基于著名的Schnorr协议生成。在此方案的基础上,使用Java语言实现了该身份认证系统。

One important mechanism for the security of application system is identity authentication that is the process of confirming a valid user by some means. Joining the static-password mechanism and the dynamic-password mechanism,a double-factor identity authentication scheme is developed.The static password is encrypted using the MD5 algorithm and the dynamic password is implemented based on the famous Schnorr protocol. At last the identity authentication system is implemented in Java.
