一次性口令技术的研究

The Study of One Time Password Technology

LeslieLamport一次性口令认证方案是一种著名的口令认证方案,但存在不足之处:如果用户想为远程系统重新生成口令链,或为新的远程系统生成口令链,则必须再次到特定的系统注册,这很不方便,也不灵活 为解决该问题,提出了一种初始化和修改一次性口令的方案.

Lamports OTP authentication is one of the famous password authentication schemes.But there are some disadvantages:when a user re generates the password chain for the original remote system or generates the password chain for new remote system,he has to register to the special system again,which is inconvenient and not flexible enough.In order to solve these problems,a kind of scheme to initialize and modify OTP is proposed in this paper.
