摘要: 在分析盲签名固有缺点的基础上介绍了部分盲签名的概念和协议,设计了3种基于离散对数数字签名算法的部分盲签名算法,并对其安全性进行了分析.

关键词: 部分盲签名, 算法设计, 安全性分析

Abstract: The blind signature is used for hiding the message to be signed and hiding the identities of message providers. The concept and protocol of the partial blind signature are explained after the analysis of teh inherent defects of the blind signature. Three partial blind signature schemes based on the discrete logarithm are introduced and their security are analysed.

Key words: partial blind, arithmetic design, security analyses
