MDI quantum protocol for anonymous countable veto voting

In order to construct unconditionally secure anonymous countable veto protocol, we proposed a measurement-device-independent quantum secure multiparty authenticated summation protocol. This protocol adopts perfect quantum encryption and one-time pad to achieve unconditional security. In addition, the protocol uses the weak coherent pulses of the BB84 state as the quantum resource, and only needs to perform Bell state identification to complete the calculation. Combined with the idea of grouping, it is applied to the quantum anonymous veto voting scenario, which ensures the anonymity of the protocol. Under the semi-honest model, the security of the designed protocol is proved. It can satisfy the correctness, security and relatively complete voting attributes. Finally, IBM Qiskit is used to carry out simulation experiments, and the experimental results verify the correctness and feasibility of the protocol.
