提出一个基于离散对数的部分盲签名方案,分析其安全性和效率.该方案满足部分盲性、不可追踪性和不可伪造性,可以防止消息提供者滥用签名,保证签名者不能侵犯消息提供者的身份隐私.与基于Schnorr签名算法和基于DSA变形签名算法的部分盲签名方案相比,该方案效率较高.

This paper proposes a partially blind signature scheme based on discrete logarithm and analyzes its security and performance. This scheme is partially blind, untraceable and unforgeable. It prevents user abusing signature and ensures that the identity privacy of message provider can not be infringed by the signer. The scheme is more efficient than the two others based on Schnorr signature algorithm and DSA changed signature algorithm respectively.
