摘要
Lamport一次性口令认证方案是一种著名的口令认证方案 ,但存在如下不足之处 :如果用户想为原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 ,这是很不方便的 ,也是很不灵活的 .为解决这些问题 ,文中提出了一种新的一次性口令认证方案 .分析表明 ,该方案与Lamport方案同样安全、有效 ,但却比Lamport方案灵活、方便 .
Lamport's one_time password authentication is one of the famous password authentication schemes. But there are some disadvantages: when the user re_generates the password chain for the original remote system or generates the password chain for a new remote system, he has to register to the dedicated system again, which is inconvenient and not flexible enough. In order to solve these problems, a kind of one_time password authentication scheme is proposed in the paper. It is shown that our scheme is as secure and almost as efficient as Lamport's scheme, but our scheme is more flexible and convenient than Lamport's scheme.
