Hierarchical Anonymous Voting Scheme Based on Threshold Ring Signature

Abstract

Voting is a commonly used method in modern democratic society,involving many fields such as politics,stock companies,court decisions,etc.Voting is regarded as a specific form of balloting,with only two candidates in pro and con.Blockchain is a digital accounting technology with the characteristics of time stamp,openness and non-tamperability which satisfy the transpa-rency and verifiability of voting.In order to realize the anonymity of voting,this paper uses ring signature to hide the correspondence between voting content and the voter.This paper puts forward a hierarchical anonymous voting scheme,which realizes the legitimacy,confidentiality,non-repeatability,updateability and verifiability of voting.By creating a hierarchy mechanism for the voting of virtual identities,it can be used in situations where the votes vary from vote to each voter,and this agreement applies the threshold ring signature scheme to the voting scene for the first time,making the voting process simple and efficient for the final voting results once one party has more than half of the votes cast.
