Quantum anonymous one-vote veto protocol based on BB84 states

In order to construct unconditionally secure one-vote veto protocol, a primitive protocol of secure multiparty computations was defined, i.e., secure multiparty disjunction. Furthermore, by introducing a quantum cloud, a quantum secure multiparty disjunction (QSMD) protocol was proposed. BB84 states were took as quantum resources and only single-photon operations and measurements were needed. To avoid the flaws of infeasibility, i.e., most of existing quantum voting protocols need to perform operations and measurements in high-dimensional Hilbert space, a quantum anonymous one-vote veto protocol with a quantum cloud (QAOVC) was designed by using the QSMD protocol. In addition, to decentralize, a quantum anonymous one-vote veto (QAOV) protocol without any third party was presented. Compared with related protocols, the proposed protocols require less quantum resources and simpler operations, so they have better feasibility. Under the semi-honest model, quantum perfect encryption and classical one-time pad can ensure the unconditional security of the proposed protocols, i.e., it can completely meet secure requirements of one-vote veto and perfectly protect the privacy of the voters. Finally, simulation experiments are implemented on IBM Qiskit, and the experimental results show that the protocols are correct and feasible. © 2022 Editorial Board of Journal on Communications.
