摘　　要：电子投票由于其高效率的优势已在大多数国家被投入使用,但现存电子投票方案都存在一定程度上的隐私泄漏问题。采用区块链和安全多方计算技术构造了一种匿名条件下多候选者的电子投票方法,可保证在匿名条件下单个实体对多名候选者进行投票的同时,无法获得其他投票者的投票情况,并可以在计票阶段保证计票结果的真实与准确,不可篡改。该方法满足电子投票系统的基本安全标准。Electronic voting has been used in most countries in the world due to its greater efficiency.However,the existing e-voting solutions have some degree of privacy leakage problems.Secure multi-party computing as a kind of invisible technology for data availability has natural advantages for the protection of users’privacy information,while blockchain itself has characteristics of decentralization and data immutabilities.This paper constructs a multi-candidate e-voting method under anonymous conditions by using blockchain and secure multi-party computing technology.The system can ensure that a single entity can vote for multiple candidates under anonymous conditions and cannot obtain the votes of other voters,and can guarantee the true and accurate vote counting results in the vote-counting stage without tampering.The method meets the basic security standards of e-voting systems.
