摘要
回顾了电子现金的研究现状,并对几种常见方案进行了分析。基于盲签名在线电子现全系统,设计了一种基于可信第三方的电子现金系统。方案除具有一般电子现金系统的匿名性和可控性外,增加了电子现金跟踪和电子现金所有者跟踪双重功能。使用了部分盲签名技术,减小了数据库大小,提高了查找速度,在安全性和可控性方面得到了加强和提高。
Research status quo of electronic cash is reviewed and several common schemes are analyzed in this paper. Based on the online electronic cash system of blind signature, an electronic cash scheme based on the trusted third-party is proposed and implemen-ted. In addition to the anonymity and controllability of the general electronic cash system, the dual function of electronic cash tracking and electronic cash owners tracking are added to the proposed scheme. Meanwhile, with partial blind signature technology to reduce the database size, the search speed, the security and controllability are all enhanced.
