Abstract:

The use of security protocols to protect the privacy of voter and ensure the fair and effective voting is the basis of electronic voting applications, but the complexity of the security protocol is the biggest obstacle to electronic voting applications. A multicandidate electronic voting protocol based on RLWE homomorphic encryption algorithm,which can support multicandidates and satisfy the privacy protection of voters. Based on additive homomorphic properties of the RLWE homomorphic encryption algorithm, this protocol protects voters by counting cryptograph in the count stage, and uses the nature of the Chinese remainder theorem to improve the counting ability. This  protocol can support multicandidates to vote and eventually know the final vote number of each candidate,and set up publicity institutions to show every voting process in each steps for public verification.
