结合现实生活中人工投票的实际需求,提出了一种新的基于量子秘密共享的安全投票协议。在该协议中,每一组四重态GHZ中的4个粒子依次 分发给投票人Alice、验证人Bob、签名人兼内部审计人Charlie以及外部审计人Trent, Alice测量自己的粒子将投票信息传递出去, Charlie、 Bob和Trent通过测量自己的粒子完成签名、验证和审计工作。与以往协议相比,该协议角色全面且都能实质性地参与投票的相关活动, 避免了使用复杂的量子指纹函数,技术上易于实现。由于采用了双重监督,选票管理中心内部、外部对选举结果的权威性均高度认同。

Combined with the actual demand of artificial vote in real life, a new secure voting protocol based on quantum secret sharing is proposed. In the protocol, four particles of each group of four-particle GHZ-state are delivered to the voter Alice, verifier Bob, signatory and internal auditor Charlie and external auditor Trent respectively. Alice measures the particles of her own to vote her message out. Charlie, Bob and Trent complete the signature, verification and audit work by measuring their own particles. Compared with the previous protocols, the roles in the proposed protocol are comprehensive and they can be substantially involved in voting related activities. It avoids the use of complex quantum fingerprint function, so it 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.
