Abstract

Blockchain technology has become a popular choice for electronic voting systems due to its transparency, security, and decentralization. However, it is not a perfect solution, as its inherent immutability poses challenges in blockchain-based e-voting systems. Specifically, without the physical security provided by traditional polling stations, preventing bribery and coercion becomes more difficult. Additionally, because of blockchain’s immutability, voters who are coerced or mistakenly vote cannot correct their choice. To address these issues, this paper proposes a secure blockchain-based voting system with editable ballots. The system uses chameleon hashes with ephemeral trapdoors and a timestamp mechanism, allowing voters to modify their ballots within a legitimate timeframe. Additionally, a modified Paillier cryptosystem and blind signature technology are used to ensure that any modifications leave no trace. We simulate and evaluate the system using Fabric 2.2, focusing on computational complexity and system stability. Analysis of experimental results shows that the blockchain-based voting system with an editable ballot mechanism proposed in this article has good computational cost and stability performance under normal use pressure.

安全可编辑：一种基于变色龙哈希的区块链投票系统

区块链技术由于其透明度、安全性和去中心化，已经成为电子投票系统的热门选择。然而，它并不是一个完美的解决方案，因为它固有的不变性给基于区块链的电子投票系统带来了挑战。具体来说，没有传统投票站提供的人身安全，防止贿赂和胁迫就变得更加困难。此外，由于区块链的不变性，被强迫或错误投票的选民无法纠正他们的选择。为了解决这些问题，本文提出了一种安全的基于区块链的投票系统，具有可编辑的选票。该系统使用变色龙散列，带有短暂的陷阱门和时间戳机制，允许选民在合法的时间范围内修改他们的选票。此外，还使用了改进的Paillier密码系统和盲签名技术来确保任何修改都不会留下痕迹。我们使用Fabric 2.2对系统进行模拟和评估，重点关注计算复杂度和系统稳定性。实验结果分析表明，本文提出的具有可编辑投票机制的基于区块链的投票系统在正常使用压力下具有良好的计算成本和稳定性能。
