Single particle electronic voting scheme based on quantum ring signature

Abstract

Based on the ring signature approach, this paper proposes a quantum voting protocol using single-particle states where voters can choose their voters from among the candidates without revealing their identities. In this protocol, voters hide their voting information into the envelope prepared by the voting center and the vote-counter through the quantum Fourier transform and the unitary operation, the voting center and the vote-counter will each generate only half of the voter’s identity information, and the voter’s identity information is secured by the mutual supervision of the voting center and the vote-counter. Because the protocol uses single particle states, which effectively reduces the difficulty of implementing this protocol, the security analysis shows that the protocol is secure.
