论文摘要
本文介绍了两种隐私投票系统的方法:基于盲人签名的投票(BSV)和基于均匀加密的投票(HEV)。 BSV是简单,稳定且可扩展的,但需要与区块链通信中的其他匿名属性。 HEV同时保护投票隐私免受交通分析的攻击,以防止恶意选民的合作中断,但可伸缩性有限。我们进一步应用采样以减轻HEV中的可伸缩性问题,并在不同的投票组规模和样本数量下模拟性能。
This paper presents two approaches of privacy-preserving voting system: Blind Signature-based Voting (BSV) and Homorphic Encryption Based Voting (HEV). BSV is simple, stable, and scalable, but requires additional anonymous property in the communication with the blockchain. HEV simultaneously protects voting privacy against traffic-analysis attacks, prevents cooperation interruption by malicious voters with a high probability, but the scalability is limited. We further apply sampling to mitigate the scalability problem in HEV and simulate the performance under different voting group size and number of samples.
