Decentralized quantum anonymous veto voting scheme based on measurement-device-independence

To remove any trusted third party from the voting scheme, a new primitive quantum secure multiparty exclusive OR protocol based on Measurement-Device-Independence (MDI) is presented by utilizing entanglement swapping of Bell states. Based on this primitive protocol of quantum secure multiparty protocol, a novel quantum anonymous veto voting scheme is constructed, which can meet complete security attributes. Especially, this scheme does not need any third party to count the votes, while all voters can tally the voting results by themselves. At the same time, blockchain is introduced for supervision, so that the voters can verify the validity of the voting content under extreme circumstances. The voting scheme takes Bell states as quantum resources and only performs Bell states identification based on the principle of MDI, so it is feasible to implement this scheme with the present quantum information processing technologies. Finally, the proposed voting scheme is simulated in IBM Qiskit, and the simulation results show that this scheme is correct and feasible.
