Electronic voting protocol based on ring signature and secure multi-party computing

摘要

In the context of the rapid development of the Internet, traditional voting activities are generally replaced by electronic voting. In the process of electronic voting, the counting of votes mostly relies on third-party organizations, and the third party's non-dependency and complete control over the voting information can easily lead to the insecurity of information and a large number of privacy leaks. To solve this problem, this paper uses secure multi-party computing and blockchain ring signature technology to propose a fair and safe electronic voting protocol. Our uses secure multi-party calculations to enable the counting of votes to be completed without a trusted third party, and uses the unconditional anonymity and unforgeability of ring signature technology to further ensure the security of the protocol. In the end, the security of the protocol is analyzed one by one. The analysis results show that the voting protocol satisfies several security attributes of electronic voting, and is more secure and reliable than the traditional electronic voting protocol.
