Distributed electronic voting method and system based on block chain

Abstract

The invention discloses a distributed electronic voting method and system based on a block chain. A homomorphic signcryption algorithm is utilized to hide votes, the homomorphic attribute and the aggregation attribute of homomorphic signcryption can enable voters to realize vote allocation and distributed vote counting under the condition of not revealing the content of the votes, and meanwhile, the signcryption attribute can guarantee the confidentiality and verifiability of the votes. Based on the block chain platform, vote collection, vote counting process and result disclosure are all carried out on the block chain system, and two rounds of verification are added in voting and vote counting stages, so that malicious behaviors of dishonest voters are prevented. In addition, the voting method can ensure that the voting process is highly transparent, votes cannot be forged and tampered, and a third party is not needed.

Description

technical field

[0001] The present invention relates to the technical field of distributed electronic voting, in particular to a blockchain-based distributed electronic voting method and system. Background technique

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Electronic voting has gradually become the mainstream voting method, but there are many challenges in electronic voting, and there are many attribute requirements for electronic voting, such as: security, anonymity, legality, fairness, and verifiability. Most electronic voting mechanisms do not fully satisfy all of the above requirements, and seldom achieve efficient multi-candidate voting while satisfying the basic properties. In the prior art, many electronic voting schemes require a third party to supervise the voting and counting of votes, which will lead to leakage of voters' privacy, increase t...
