Research On Trust Management Of Node Behavior In Quantum Communication Network

The research topic of this paper is derived from the National Natural Science Foundation(No.61572086,No.61402058).Compared with the classical communication network,quantum communication network can realize the security of strict mathematical proof,and it has become the next generation communication network which has been developed by all countries in the field of information security.Western developed countries even to raise the level of national security strategy,increase investment efforts to ensure that the next generation of communication network before the advent of seize the commanding heights of information technology to ensure that the information technology industry and high-tech industry's great advantage.However,quantum communication is currently the main means of communication is point to point communication,and the classic communication network of multi-user,network distance is also very different.Because of the existing conditions can not meet the ideal physical communication of quantum communication,resulting in quantum communication network there are many uncertainties and security,if not a good solution to these uncertainties and security issues,will become a constraint quantum communication in the development of network applications.In fact,the future of quantum communication and traditional communications,the same there is the node of the tampering information,behavior,and node privacy disclosure of the problem.How to solve these problems is to solve the problem of trusted management of node behavior,and the key to solve these problems lies in combining with the basic physical characteristics of quantum communication,and research and put forward a trusted management model and method of node behavior for quantum communication network.Based on the above background,this paper first studies the basic characteristics of quantum(including quantum entanglement and quantum teleportation),and introduce the trusted factors that affect the behavior of node nodes,and uses quantum teleportation to securely transmit node-related trust information Based on this,a credible evaluation model of intuitionistic fuzzy set theory node behavior based on analytic hierarchy process is proposed.The model can be used to evaluate the node behavior in quantum communication network,and the model is verified by an example.Feasibility and security.Secondly,this paper proposes a quantum group signature scheme based on GHZ state to solve the problem of trusted management of node behavior,which may be related to information tampering,behavior denial and node privacy disclosure in the quantum communication network.This paper validates that the model can effectively prevent the tampering of the node information,the behavior of the discrepancy and the privacy disclosure.Finally,the essence of the communication is that the resource sharing is the largest and the resource sharing is the largest in the quantum communication network.Through the study of quantum entanglement properties By combining resource sharing with quantum entanglement,a resource access control protocol based on Bell state is proposed.At the same time,the feasibility of the protocol is verified and the security of the protocol is analyzed.This is the node of future quantum secure communication Behavioral trust management provides a valuable new idea.
