DHS-Voting: A Distributed Homomorphic Signcryption E-Voting

Abstract

In electronic voting, voters encrypt their ballots and post them on a bulletin board, where the results are tallied by authorities. The right to tally is fully controlled by authorities, who generates a certificate to prove the results are correct, but their attempts to tamper with the bulletin board and falsify the certificate are inevitable. Therefore, we propose an electronic voting scheme based on distributed encryption and homomorphic signcryption, DHS-Voting, which can not only enable the verification of signatures to be completed quickly, but also allows anyone to get the result of the election with the help of the authorities, making the election results more credible. In addition, we prove that DHS-Voting satisfies the ballot privacy and some necessary properties of electronic voting, which we will prove in detail in the paper.
