Quantum Voting Protocol Based on Blind Signature

Abstract

AbstractAiming at the problem of high technical difficulty in the implementation of quantum voting protocol, a quantum voting protocol based on blind signature is proposed, which avoids the use of complex quantum fingerprint function and realizes the voting process of quantum blind signature by using the five particle entangled state in quantum cryptography. Among them, voter Alice transmits voting information by measuring particle state, and Bob, Charlie and Trent complete signature, verification and audit by measuring single particle state through Z-basis. Since the signed message is invisible to the signer, it is a quantum voting protocol to protect the anonymity of signed messages. Therefore, all keys in this protocol are issued by BB84 protocol, and one-time encryption algorithm is adopted, which has unconditional security, Compared with the existing quantum voting protocols, the proposed voting protocol selects a simpler measurement base, has simple measurement operation, easy implementation and high execution efficiency. It is a safe and efficient quantum voting protocol.KeywordsQuantum voting protocolBlind signatureQuantum cryptographyFive particle entangled state
