摘要: 本文给出了一个新的实用的电子投票方案。投票人被划分为不同类别,可以分别统计每一类投票人对问题的看法。协议采用了比特承诺技术和基于双线性配对的部分盲签名技术。投票人利用比特承诺技术来隐匿选票,认证中心将投票人类别标识嵌入到签名信息中,用来区分不同的类别。与文献[4,5]相比,实现该协议的计算量小,无论将投票人划分为多少个类别,协议所需的轮数不变,而且可以适应多种类型的选举。

Abstract: A new and practical electronic voting scheme is proposed by using bit commitment technology and partially blind signature which is based on bilinear pairing. In the protocol, voters were divided into the different category and we can count the view of different category. Voters keep the confidentiality of votes with bit commitment. Authentication center inserts the ID of privilege subsets into signatures, which can be used to distinguish different privilege subsets. Compared with the protocol of [4,5], Computational complexity is small,the round of voting is independent of the number of privilege subsets and can adapt many kinds of election.

Key words: electronic voting, partially blind signature, bilinear pairing, bit commitment
