一个隐私保护、去中心化和功能性的比特币电子投票协议

A privacy-preserving, decentralized and functional Bitcoin e-voting protocol

Zijian Bao, Bin Wang, Wenbo Shi

摘要:

比特币作为一种去中心化的数字货币,引起了广泛的研究兴趣。基于比特币相关协议的研究很多,基于比特币的投票协议也受到了相关文献的关注。在本文中,我们提出了一个基于比特币的去中心化隐私保护投票机制。假设有n个选民和m个候选人。获得t张选票的候选人可以从每个选民那里获得x个比特币,即总共nx个比特币。我们使用洗牌机制来保护选民的投票隐私,同时使用分散的门限签名来保证安全性和分配投票权。该协议具有正确性、去中心化和隐私保护的特点。与其他方案相比,我们的协议具有更少的事务数,可以实现更功能的投票方法。

英文摘要:

Bitcoin, as a decentralized digital currency, has caused extensive research interest. There are many studies based on related protocols on Bitcoin, Bitcoin-based voting protocols also received attention in related literature. In this paper, we propose a Bitcoin-based decentralized privacy-preserving voting mechanism. It is assumed that there are n voters and m candidates. The candidate who obtains t ballots can get x Bitcoins from each voter, namely nx Bitcoins in total. We use a shuffling mechanism to protect voter's voting privacy, at the same time, decentralized threshold signatures were used to guarantee security and assign voting rights. The protocol can achieve correctness, decentralization and privacy-preservings. By contrast with other schemes, our protocol has a smaller number of transactions and can achieve a more functional voting method.
