一个基于Mix net的电子投票方案

An Electronic Voting Scheme Based on A New Mix Net

电子投票是电子政务活动中的一项基本功能 .本文设计了一个新的具有 (t- 1,N - 2 ) AA弹性的可验证Mixnet协议 ,该协议具有秘密性、正确性和可验证性 .协议所需的通信量和计算量优于已知方案 .利用它给出了一个电子投票方案 ,具有选举的秘密性、唯一性、完整性、匿名性、可公开性、可验证性等优点 ,适宜于大规模选举 .

A new Mix net protocol is presented.Given an array of encrypted messages,two different groups of mix servers blind and decrypt the same array,which makes our protocol( t,N-2) AA -resilience.Its communication and computing costs are less than other verifiable Mix net that we know presently.A secure electronic voting scheme based on it is also proposed which has the following property:privacy,fairness,publicity,public verifiability,and voter's anonymity simultaneously.
