摘　　要：针对电子投票中用户信息隐私泄露、重复投票、投票内容泄露、选票篡改等问题,提出一种基于属性证书的匿名电子投票方案。该文利用零知识证明协议实现基于属性的证书认证和用户的完全匿名性;利用ElGamal加密技术和引入选票管理服务器(VMT)保证了选票的公平性;采用双重Id(CertId,选票ID)形式保证选票的可验证性。理论和实验分析表明:该方案具有匿名性、公平性、唯一性等特性,解决了CA半可信以及CA与投票机构VI合谋等问题,可以广泛应用于各种选举活动。Aimed at the problems of user information privacy leakage,repeated voting,voting content leakage,and ballot tampering in electronic voting,an anonymous electronic voting scheme based on attribute certificates is proposed.It used zero-knowledge proof protocol to achieve attribute-based certificate authentication and complete user anonymity,used ElGamal encryption technology and the introduction of a vote management server(VMT)to ensure the fairness of votes,and used double Id(CertId,ballot ID)to ensure votes verifiability.Theoretical and experimental analysis shows that the scheme has the characteristics of anonymity,fairness,and uniqueness,and solves the problems of CA semi-credibility and the collusion between CA and voting agency VI,and can be widely used in various election activities.
