Abstract: According to the actual demand of artificial vote in real life, the paper proposes a new secure voting protocol based on quantum secret sharing. In the protocol, the four particles of each group of four-particle GHZ-state are delivered to the voter Alice, the verifier Bob, the signatory and internal auditor Charlie and external auditor Trent respectively. Alice measures the particles of her own to vote her message out implicitly, and then Charlie, Bob, and Trent complete the rest signature, verification and audit work by measuring their own particles. Compared with previous protocols, the roles in the protocol are comprehensive and they can be substantially involved in voting related activities. In particular, the use of complex quantum fingerprint function is avoided, so the protocol is easy to implement technically. Because of the dual supervision, the authority of the election result will be highly recognized by the internal and external of the ballot management center.
