Research And Design Of Semi-Quantum Voting Protocol

With the development and popularization of computer networks,electronic voting has become the most common used voting method due to its low cost and easy operation.It can be applied to network surveys,various elections and other scenarios.Since the security of classical electronic voting relies on solving difficult mathematical problems,it faces many security risks with the advent of quantum computers.The security of quantum voting based on the principles of quantum mechanics provides a new way to solve this problem.It not only prevents the leakage of important information,but also protects the security of voting information.However,factors such as the incomplete maturity of quantum computers and the expensive quantum resources limit the application of quantum voting in practical scenarios.Semi-quantum voting has the same security as quantum voting,and requires fewer quantum resources,which is more suitable for the current level of quantum technology.This thesis studies how to resist attacks from illegal voters and use less quantum resources to build a secure semi-quantum voting protocol.The main work of the thesis is as follows:1.Aiming at the problems of cumbersome voter voting operations and excessive quantum resources consumed in the existing quantum voting protocols,a semi-quantum voting protocol based on single particles is proposed,which greatly reduces the cost of quantum voting.In this protocol,the voters are semi-quantum parties,and voting can be completed by simple operations on the voting particles,which reduces the workload of the tellers accordingly.The semi-quantum voting protocol has the same security as quantum voting,and requires fewer quantum resources and it is more practical.At the same time,the protocol uses a single particle as a carrier,which has a qubit usage efficiency that cannot be achieved by other protocols.2.Aiming at the problem that the existing quantum voting protocol cannot effectively resist the false signal attack and the distributed voting consumes too much quantum resources,a new semi-quantum voting protocol based on the distribution model is proposed.The protocol not only meets the security requirements of legitimacy,non-reusability,and privacy,but also effectively resists internal and external attacks.Compared with the currently proposed protocol,the semi-quantum model strictly limits user capabilities to save costs.The protocol uses this advantage to reduce the consumption of quantum resources to a certain extent.
