基于多方排序协议的安全电子投票方案

摘要

Compared with the traditional voting, electronic voting(e-voting) not only has many advantages, but also exists many security problems. The full privacy of electronic voting is an important index to evaluate the security of the voting scheme, it implies the privacy of the voters and candidates for privacy protection, especially the protection of total votes for the losers. This paper designs a secure multi-party ranking protocol via using the verifiable secret sharing. We propose a new secure electronic voting scheme based on the proposed multi-party ranking protocol. The e-voting scheme is full privacy.%与传统投票相比较, 电子投票拥有许多优势, 也存在重要的安全问题. 电子投票的全隐私性是评估投票方案安全的重要指标, 它是指对投票者的隐私保护和候选者的隐私保护, 特别是落选者的得票数的保护. 利用可验证秘密共享的思想提出了一个安全多方排序协议, 并将它运用到电子投票中, 设计了一个新的安全的电子投票协议, 本协议具有全隐私性.
