盲签名是一种所签的消息对签名者不可知的数字签名。从1983年David Chaum首先提出了盲签名的概念以来,许多实现方案相继推出。文章提出了基于离散对数问题的一般盲签名方案,对其完备性、不可伪造性、安全性以及盲性进行了分析,并给出了用该方案设计一个有效的盲签名协议应该满足的参数规则。

A blind signature is a digital signature in which the message to be signed is blind to the signer.After David Chaum introduced this concept in 1983,many implementations have come into being.In this paper,we present a general blind signature scheme based on the discrete logarithm problem.Then,a detailed analysis on its completeness,unforgeability,security and blindness is given.We also discuss some rules,which have to be followed to design a valid discrete-logarithm-based blind signature protocol with this scheme.
