【摘要】 很多的身份认证系统对于合法用户的登录特征的控制审核上存在着许多的缺陷。设计通过加入时间戳的方式,实现了一种在登录时间上不可否认的增强的可审核机制;采用基于DSA数字签名的认证方案,在法律上保障了本系统的安全性;系统设计模型实现了客户端软件和密钥存储物理上的分离,在安全性、实用性和可扩展性方面得到了增强。更多还原

【Abstract】 There were lots of defects for logging characters about legal users in many Identity authentication systems.By the means of additional time-stamp,this system realized a kind of stronger audited mechanism,in which logging time was undeniable to customers.Authentication measure made use of the DSA digital-signature to guarantee the safety of this system on the law.The design model to this system realized the separation of client software and password key in physical location,thus it was strengthen about security,practicability and expansibility.更多还原
