A blockchain-based privacy protection electronic voting method and system

Abstract

The invention discloses a privacy protection electronic voting method and system based on a block chain. The method includes: determining voting rules, and establishing multiple voting nodes and one or more verification nodes in the block chain according to the voting rules; Generate voting keys and corresponding homomorphic encryption algorithms according to preset rules; each node of the plurality of voting nodes receives votes from voting participants, and encrypts the votes according to the voting keys, and encrypts the votes Send to the verification node; the verification node receives the encrypted votes sent by multiple voting nodes, performs voting statistics calculation according to the homomorphic encryption algorithm, and obtains the encrypted voting statistics result; according to the decryption corresponding to the voting key The key decrypts the encrypted voting statistical results to obtain the voting statistical results; the method and system realize the openness, transparency and privacy security guarantee of electronic voting by setting the key and based on homomorphic encryption and zero-knowledge proof.

Description

technical field [0001] The present invention relates to the field of Internet technologies, and more specifically, to a method and system for privacy-protected electronic voting based on blockchain. Background technique [0002] With the development of Internet technology and modern cryptography technology, electronic voting, as a new voting method, has gradually attracted the attention of the society, and many experts and scholars have invested in research in the field of electronic voting. Electronic voting is based on various cryptography technologies and completes the entire voting process through computers and networks. Its goal is to provide a safe, convenient and efficient voting environment on the Internet. Compared with traditional voting, electronic voting has the advantages of fast and accurate counting, saving manpower and expenses, and ease of use of voting. However, voting through the Internet has brought some problems, such as fraudulent votes, repeated votin...
