利用群签名协议和时限承诺协议,本文给出了一种新的基于匿名通讯信道的安全电子投票方案.诚实投票者的身份无条件保持匿名,然而不诚实的投票者一定能被可信赖的注册机构追踪到.可证明:即使管理机构和计票机构勾结,在计票前可同时保证选票的秘密性和公平性.除此之外,我们的方案解决了"选票碰撞","投票者弃权或中途退出"等问题.

A secure electronic voting scheme based on anonymous communication channel is proposed by using group signature protocol and timed commitment protocol.The identity information of honest voters can be protected unconditionally while dishonest voters are sure to be traced by the trusted registration agent.We can also prove:Even the administrator and the counting agent conspire,the voting privacy and fairness can be realized simultaneously before the counting.Besides,we also solved the problems such as "vote collision","voter abstains from voting or quits midway" et al.
