摘要
给出了一个新的实用的电子投票协议,主要采用了基于双线性对的门限部分盲签名方案和比特承诺技术。门限签名方案将密钥进行分享,限制了由单个签名者所组成的系统的不安全性。而通过部分盲签名技术的使用,可以使签证中心将投票人类别标识嵌入到签名信息中,进行分类统计。该协议不仅满足一个理想电子投票系统的基本性质,而且增加了安全性和灵活性,是一个较为实用的方案。
A new and practical electronic voting scheme is proposed by using threshold partially blind signature scheme from bilinear pairing and bit commitment technology.A threshold signature scheme distributes the signing abilities to a group of signers and avoids the system insecurity.Using partially blind signature,authentication center can insert the identification of voter＇s class into signatures and count the view of different classes.This protocol has all properties of an ideal protocol and also enhances the security and flexibility.It has practicality.
