| 摘 要： | 为进一步完善ELGam al盲签名体制,研究了基于ELGam al签名方程的盲签名方案。概述了盲签名的定义及其分类标准,基于不同的签名方程,和有限域上离散对数难解性假设,得到了相应的强盲签名和弱盲签名方案。首次系统地对不同的ELGam al签名方程进行了盲性研究,并对每个盲签名方案进行了盲性分析和安全性分析。

| Abstract: | In order to improve the ELGamal blind signature scheme,this paper studies the blind signature schemes based on the ELGamal signature equations.Following a summary of the definition and classification standard of blind signature,based on the different signature equations and the assumption of difficulty in solving the discrete logarithm problem on the finite field,we get the corresponding strong blind signature and weak blind signature schemes.It's the first time to analyze the blind properties of the different ELGamal signature equations.Finally we give the blind analysis and security analysis to each blind signature scheme. |
