基于服务器端动态时钟的网络一次一密口令模型

The Model of Net Once One Password based on Server Dynamical System Time

网络一次一密口令的提出,可以较好地克服现行口令机制的缺陷,论文在已有模型的基础上,提出了由服务器端动态分配系统时间,实现整体网络用户口令的一次一密;同时系统初始化密码和用户口令密码分离,兼顾了系统口令的安全性与用户口令的简便性。模型对穷举攻击等也有极好的防御能力。

The net once one password can overcome the drawback of current password system. Based on the current model, this article suggests that the server could dynamically distribute the system time and make net users on network once one password, and at the same time the initial cryptogram and user password are separated, thus giving consideration to both system password security and user password simplicity. The model can defend net from exhaustive attack
