双向隐私保护量子投票协议

Two-way Privacy-protected Quantum Voting Protocol

量子投票协议是利用量子的部分特性设计的电子投票协议.目前的量子投票协议忽略了双向隐私保护,即在保证投票者隐私的前提下,对落选者投票信息的隐私保护.设计了一个六方参与的量子投票协议,应用五粒子纠缠态实现量子代理盲签名,应用半量子秘密比较协议实现票数的秘密比较.前者能够分离投票者身份信息和投票信息以实现对投票者隐私的保护,后者能够秘密比较候选人票数以实现对候选人隐私的保护.设计的量子投票协议以传统量子投票协议为框架,增添了新功能,投票过程安全可靠可监督,协议传统安全性和抗量子性得到了保证,且无过多量子资源的使用,可以实现完整的大基数投票过程.

Quantum voting protocol is an electronic voting protocol designed by using some properties of quantum.The current quantum voting protocol ignores the two-way privacy protection,that is,the privacy protection of the unsuccessful candidate's voting information on the premise of ensuring the privacy of voters.A six-party quantum voting protocol was designed,which uses the five-particle entangled state to realize the quantum proxy blind signature,and uses the semi-quantum secret comparison protocol to realize the secret comparison of votes.The former can separate voter identity information from voting information to protect the privacy of voters,while the latter can secretly compare the votes of candidates to protect the privacy of candidates.The designed quantum voting protocol took the traditional quantum voting protocol as the framework and added new functions.The voting process was safe and reliable and can be supervised.The traditional security and quantum resistance of the protocol were guaranteed,and there was no excessive use of quantum resources,which can realize a complete large-base voting process.
