A Secure Quantum Voting Scheme Based on Quantum Group Blind Signature

Abstract

We proposed a secure quantum voting scheme employing five-qubit cluster state as quantum channel. It is based on quantum group blind signature. With the help and supervision of group manager Charlie, voters Alice sends vote and opinions and proposal to verifier Bob. Meanwhile, voting requires the signature of the organization administrator David. Adopting the techniques of group signature and blind signature, it can flexibly add new voters and enhance the message owner’s anonymity. Moreover, it uses quantum key distribution and one-time pad to guarantee its unconditional security. In addition, this scheme analyses the resistance under various attacks and proves that is an efficient and secure scheme.
