A Secure Voting Scheme Based on Quantum Walk

Quantum walks is a technology that has been widely used in quantum computing and quantum signatures. This article proposes a secure voting scheme based on quantum walks to address issues such as number limitations in quantum voting. The proposed scheme utilizes single-qubit particles to blind the voting information, and then uses quantum walks techniques to transmit the information. This scheme utilizes quantum encryption technology, ensuring its unconditional security in theoretical terms. The security analysis indicates that the scheme can effectively defend against various forms of attacks. Theoretically, it achieves unconditional security and provides effective anonymity protection for voters' identity information. Compared with other quantum voting schemes, the proposed approach has better feasibility.
