摘要
针对电子投票中胁迫选票、重复投票、投票人隐私泄露等安全性问题,文章基于联盟链提出了一种全匿名电子投票方案。该方案利用区块链技术中的智能合约完成计票过程,避免了传统可信第三方的约束,确保投票的公平性。方案采用可链接环签名实现对投票者身份的无条件匿名。理论分析的结果表明:该方案具有保密性、匿名性、公平性等性质,可以广泛应用于特定团体内的电子投票。
An anonymous electronic voting scheme based on alliance chain was proposed to solve the security problems such as intimidation of votes, repetition of votes and disclosure of voters’ privacy in electronic voting. The smart contract in blockchain technology is applied to complete the counting process, avoiding the constraints of the traditional trusted third party, and ensuring the fairness of voting. For purpose of realizing unconditional anonymity of the user’s identity, a linkable ring signature is adopted in this scheme. The theoretical analysis results show that the scheme has the characteristics of confidentiality, anonymity, fairness, and can be widely used in electronic voting in specific groups.
