The Damage Model And Repair Strategy Research Of Quantum Signaling Based On Malicious Attacked

Quantum communication as an absolutely safe new communication, its biggest advantage is its security confidentiality, therefore, this paper mainly security confidentiality of the communication process to make certain studies.We focus on quantum signaling transport security. Quantum signaling plays a control role in quantum communication, so its study is essential. This paper focuses on the attacks damage model and repair strategies of the third-party malicious in quantum signaling transmission, and conducted in two parts:one is that a quantum signaling transmission system of multi-user is presented, elaborated in the transmission process signaling channels, make quantum communication in the reality of a step closer to a large scale application. We considers the damage model of Photon Number Splitting attack (Photon Number Splitting, PNS) to signaling in the transmission process, and the idea of decoy state is introduced to the safety of quantum signaling in direct communication, Analyzed the different light intensity to send the light pulse to overcome PNS attack,so as to improve the safety of the signal transmission.The simulation result shows that repair strategy of multi-user quantum signaling transmission system being attacked can effective detect the Photon Number Splitting attack, and increase distance of security transmission,to ensure the signaling transmission process safely and effectively.Another is that a quantum signaling tree transmission system of multi-user is presented, elaborated the transmission process of signaling.We consider the damage model of Trojan horse attack to signaling in the transmission process and the necessity of repair. The idea of quantum key distribution is introduced to the safety of quantum signaling in direct communication analyzed non-orthogonal quantum states to overcome the problem of Trojan horse attack. So as to improve the safety of the signal transmission.Quantum signaling tree transmission system of multi-user is improved, a new general transmission model of multi-user quantum signaling tree topology is presented. The result shows that repair strategy of multi-user quantum signaling transmission system being attacked can effective detect the Trojan horse attack, and increase distance of security transmission, to ensure the signaling transmission process safely and effectively.
