基于区块链和简短可链接环签名的安全电子投票方案

Secure Electronic Voting Scheme Based on Blockchain and Short Linkable Ring Signature

围绕当前多数电子投票方案存在中心化、未能实现匿名投票等问题,提出基于区块链和简短可链接环签名的安全电子投票方案.通过设计一个简短可链接环签名方案,结合区块链技术,构造了一个具体、安全、高效的电子投票方案,给出了其系统模型、算法形式化定义以及详细描述.与已有方案相比,该方案允许大规模人员投票,且支持多个投票选项以及自动计票等多个功能.安全分析和实验结果表明,该方案在满足匿名性、不可伪造性和隐私性等更多安全目标的同时在计算开销方面仍具有优势.

Surrounding the problems that most of the current electronic voting schemes are centralized and unable to achieve anonymous voting,a secure electronic voting scheme based on blockchain and short linkable ring signature is proposed.By designing a short linkable ring signature scheme and combining with blockchain technology,a specific,secure and efficient electronic voting scheme is constructed.The system model,the formal definition of the algorithms,and the detailed description are provided.Compared with the existing schemes,this scheme allows for large‐scale voting,and supports multiple voting options and automatic counting of votes.The security analysis and experimental results show that this scheme can meet more security goals such as anonymity,unforgeability,and privacy,while still with advantages in terms of computational overhead.
