基于椭圆曲线的盲签名方案设计及其应用

盲签名技术作为一种特殊的数字签名技术,在电子现金、电子投票等领域得到了越来越广泛的使用;描述了ANSI(1999)颁布的标准椭圆曲线数字签名算法和盲签名技术原理,在结合椭圆曲线密码优越性的基础上,给出了一种新的强盲签名方案,经过分析和验证,新方案具有更好的安全性;最后给出了在电子现金和电子投票系统中的应用实例,解决了电子现金中的隐私与安全问题,以及在电子投票选举中具有匿名性和公正性的问题。

Design plan of blind signature based on elliptic curve and its application

Blind signature technique,as a special digital signature technique,is more and more widely used in electronic cash,electronic poll and so on.This paper describes standard elliptic curve digital signature algorithm and blind signature technique principle which are issued by ANSI in 1999,gives a new strong blind signature plan in combination of the advantages of elliptic curve code,after analysis and test of the plan,finds that the new plan has better application safety, and,finally,gives practical examples in electronic cash and electronic ballot system.The examples given solve the problems in secrets and safety of electronic cash and in anonymity and judgment of electronic ballot election.
