The Research Of Quantum Secure Communication Protocol With Signature

Quantum secure communication utilizes quantum physics principles to ensure security such as quantum uncertainty,quantum state collapse,and quantum state entanglement.Legitimate communicators rely on quantum mechanics to detect any eavesdropper in quantum channel to ensure secure communication.A quantum secure communication protocol not only ensures that any eavesdropper can be detected in the communication process by legitimate communicators,but also the validity and non-repudiation of the communication information.However,the proposed quantum secure communication protocols only consider the security of the communication process,and no constraints on legal communication,there is risk of that communicator may deny the communication information after communication.In order to protect the authenticity and non-repudiation of communication data in quantum communication,a new quantum communication protocol is needed to meet these security requirements.Quantum signature is a kind of communication information guarantee mechanism which depends on the principle of quantum mechanics to ensure its security.Many theoretical research and experimental results prove the absolute security of quantum signature scheme theory.The application of the quantum signature mechanism can compensate for the defect of current quantum communication protocol in which information may be denied.Based on the existing quantum secure communication model,this paper solves the above problem of quantum secure communication by using the advantages of quantum signature mechanism,and proposes a new quantum secure communication protocol to realize both communication security and reliable.The main work of this paper is:1.The advantages and disadvantages of the quantum communication protocol and the quantum signature scheme are analyzed,and the advantages of the two are combined to compensate for the defects of the quantum communication protocol.A new quantum secure communication protocol with proved security is proposed.The protocol is based on the existing quantum secure communication protocol,and the advantages and security of quantum signature are combined with quantum communication protocol and quantum signature mechanism to solve the security problem in quantum communication.Through the analysis of the security of the agreement,it proves that the scheme solves the security problem proposed in this paper.2.The above scheme can be extended to multi-party communication protocols in quantum networks.To achieve secure communication in the network environment and ensure that the information in the multi-party secure communication in the quantum network system is undeniable and forged.Quantum network communication has become a hot topic in the field of quantum physics and information science.In quantum networks,there are more quantum communication between two or more communicators,and a reliable protocol is needed to realize complex quantum communication in quantum networks.Theoretical analysis proves that the scheme can guarantee the security of multi-party communication in quantum network.
