Voting protocol method based on d-dimensional three-quantum entanglement state

Abstract

The invention provides a voting protocol method based on a d-dimensional three-quantum entanglement state, and belongs to the technical field of quantum computation and quantum authentication. The voting protocol method comprises the steps that a d-dimensional three-quantum entanglement system is prepared by a voting management center, three quanta are distributed to voting groups, a scrutineer and a vote counting person correspondingly, n private shares and group authentication codes a<0> are prepared simultaneously, the private shares are distributed to n voting group registered authorized persons, t persons with the voting qualification are selected from the voting groups to participate in voting, and the group authentication codes are issued to the scrutineer; the voting groups calculate the private authentication codes of the voting groups, and vote according to the voting intentions and the private authentication codes of the voting groups; after voting is completed, the scrutineer conducts unitary operation on the quanta in the hands through the group authentication codes in the hands, and authenticate safety through measuring; and after authentication is qualified, the votecounting person obtains a voting result. Compared with other protocols, the number of the quanta required to be prepared by the voting protocol method is much less, and thus the efficiency is improved, and the protocol flexibility and universality are enhanced by using any d-dimensional quantum state.

Description

technical field [0001] The invention belongs to the technical field of quantum calculation and quantum authentication, and relates to a voting protocol method based on a d-dimensional three-quantum entangled state. Background technique [0002] In the past few decades, classical cryptography and different fields have been combined into practical applications. One of the most brilliant applications of this is group voting. The security of traditional voting protocols is mostly based on the computational complexity of discrete logarithms, quadratic residues, and factorization of large numbers in classical cryptography. However, with the rapid development of quantum technology in recent years, the powerful computing power of quantum computers poses a huge challenge to the security of these classical protocols. The quantum encryption technology in the contemporary background is based on the basic principles of quantum physics, and its security is based on the Heisenberg uncert...
