基于区块链的可追踪匿名电子投票方案

Traceable anonymous electronic voting scheme based on blockchain

电子投票在为人们提供便利并得到广泛应用的同时,也存在着数据隐私泄露等安全性问题。文章提出了一种基于区块链的可追踪匿名电子投票方案,实现了匿名性、可追踪性、公平性以及普遍可验证性。方案通过使用K次匿名认证协议,不仅保护了正常投票人的身份隐私,还能揭露多次投票的恶意投票人身份。采用基于时间释放的加密方法,可以保证任何人都不会在投票结束前知道实时的投票情况。此外,利用区块链技术可以保证选票时不被篡改,并且任何人都能在不依赖可信计票中心的情况下对选票进行验证。最后,实验结果和安全性分析表明了方案是安全可行的。

While electronic voting provides convenience for people and is widely used,there are also security problems such as data privacy disclosure.This paper proposed a traceable anonymous electronic voting scheme based on blockchain,which realizes anonymity,traceability,fairness and universal verifiability.By using k-times anonymous authentication protocol,the scheme not only protects the privacy of normal voter identity,but also reveals the identity of the malicious voter who has voted multiple times;Using a time-released encryption method,it can guarantee that no one will know the real-time voting situation before the end of the voting;In addition,the use of blockchain technology can ensure that the vote will not be tampered with,and anyone can verify the votes without relying on a trusted counting center.Finally,experimental results and security analysis show that the scheme is safe and feasible.
