Electronic voting method and device based on group signatures, electronic equipment and storage medium

Abstract

The invention provides an electronic voting method and device based on group signatures and electronic equipment. The method comprises the steps of: obtaining the historical total voting number of group members and voting information of this time; calculating the total number of current votes according to the current vote information and the total number of historical votes; generating a zero-knowledge voting proof which proves that the total number of current votes is less than or equal to the maximum voting amount; performing group signature on the to-be-signed message containing the zero-knowledge voting proof to generate group signature data; and initiating uplink storage of the voting information, the zero-knowledge voting proof and the group signature data. According to the technicalscheme provided by the invention, anonymity to other members and publicity to the group owner can be realized, so that identity protection is performed on the voter, the voter can be monitored by thegroup owner, uplink storage is initiated for current voting details, zero-knowledge voting and group signature data, and the data can be prevented from being tampered.

Description

Technical field[0001]The present application relates to the field of block chains, and in particular, to a group-signed electronic voting method and device, electronic device, computer readable storage medium.Background technique[0002]The electronic voting system is based on cryptographic principles, using technology, such as computer, Internet and other technologies to replace the traditional artificial method to realize the voting function. The electronic voting agreement is first proposed by Chaum in 1981, it is necessary to solve the legitimacy, anonymity, patch integrity, non-repeatability, unfair, and non-aerosrocation modification of the Internet environment.[0003]However, existing voting devices cannot be restricted to each person's voting due to complete anonymity of user identity. For example: User A, vote x, users can use the loop signature to be identified, completely anonymity; but due to the anonymity of voting, the number of votes of user A cannot be restricted.Invent...

AI Technical Summary

Problems solved by technology

[0003] However, due to the complete anonymity of user identity, existing voting devices cannot limit the number of votes for each person

For example: user A votes for X, the user can use ring signatures for identity protection and is completely anonymous; however, due to the anonymity of voting, the number of votes for user A cannot be limited
