一种动态口令认证方案的研究与改进

Study and Improve on a Dynamic Password Authentication Scheme

分析研究了一种动态口令方案,针对其不足,对原方案中认证依据的产生以及连接认证依据的产生进行了改进,增强了原方案的认证依据产生和修改的灵活性,实现了连接认证双方协商产生,并保留了原方案的设计思想。改进方案提高了原方案的整体安全性,并更具实用性。

Based on studying a dynamic password authentication scheme, an improved dynamic password authentication scheme is proposed, the scheme holds the design purpose of the original scheme. The generating login authentication basis and connect authentication basis is improved. In the scheme, the flexibility of generating and modifying the login authentica- tion basis is enhanced, and the connect authentication basis generation is consulted with user and server. The improved scheme is more security and practical than the original scheme, and more practical.
