Problems solved by technology

[0003] In the current electronic voting system, since the vote counting process of the vote counting nodes is not open, it is difficult to ensure the fairness of the vote counting nodes when counting votes
In addition, when voting is implemented based on ring signature technology, each voting node needs to interact with other voting nodes to generate its own ring signature. Therefore, when the number of voting nodes is large, the process of generating ring signatures for each voting node is complicated. , the amount of calculation is large, it is difficult to guarantee the overall voting efficiency, and it will affect the usability of the electronic voting system

Abstract

The invention discloses a voting method, a voting device and voting equipment based on Blockchain, and a medium. The method comprises the steps of: obtaining voting values representing a voting intention in each voting node; encrypting each voting value according to the homomorphic public key of the counting nodes generated by a homomorphic encryption algorithm to generate encrypted values; transmitting each encrypted value to a consensus node running a blockchain smart contract, and controlling the consensus node to perform a summation operation on each encrypted value to obtain an encryptedvoting result; decrypting the encrypted voting result by controlling the homomorphic private key of the counting nodes generated by the homomorphic encryption algorithm to obtain an original voting result, and recording the original voting result in the blockchain through the blockchain smart contract for publicity for each node in the blockchain network. This method ensures the fairness of the counting process and the overall voting efficiency. In addition, the invention also provides a voting device and voting equipment based on Blockchain, and a medium, having the beneficial effects the same as described above.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular to a voting method, device, equipment and medium based on block chain. Background technique [0002] Current electronic voting (e-voting) systems are often centralized systems based on blind signatures and ring signatures. During the voting process, voting nodes either interact with vote counting nodes to generate voting blind signatures, or generate voting ring signatures through the public keys of other voting nodes to achieve anonymous voting. Finally, voting nodes send blind signatures or ring signatures to The vote counting node counts the votes and publicizes the results. [0003] In the current electronic voting system, since the vote counting process of the vote counting nodes is not disclosed, it is also difficult to ensure the fairness of the vote counting nodes when counting votes. In addition, when voting is implemented based on ring signature technology, e...
