基于部分盲签名的新型电子现金安全系统研究

Research of New E-Cash System Based on Partial Blind Signature

针对当前电子现金系统中顾客信息的匿名保护及普遍存在的否认、丢失、滥用、偷窃等问题,提出了一种基于部分盲签名的新型电子现金系统,该系统的主要安全方案是在盲签名消息中加入临时匿名公钥,系统协议分析可知,该方案具有较好的综合安全性能。

Many problems exist in the systems like denying, losing, misusing, stealing, and double-spending. A new e-cash system using a modified partial blind signature scheme is introduced. This paper proposes an e-cash system in which a temporary anonymous public key is embedded in the partial blind signature against the above attacks.
