Research On Trusted Access Model Of Nodes In Quantum Communication Network

The research topic of this paper comes from the funding of the National Natural Science Foundation of China(No.61572086,No.61402058).At present,China's quantum communication technology has been the top in the world.It uses the unique characteristics of quantum states to achieve absolute security of communication,which is the biggest difference from classical communication modes.In the quantum communication research field,more and more outstanding achievements have emerged today,quantum communication technology has also become increasingly perfect.For example,the transmission distance for teleportation becomes longer and longer,and the number of entangled states of multiple particles increases.On this basis,with the investment of key infrastructures such as the Beijing-Shanghai Trunkline and the Mozi satellite,quantum communication has gradually shifted from a peer-to-peer model to a large-scale,heterogeneous,heterogeneous network model.Quantum communication networks it has also gradually entered the stage of practical application.The development of quantum communication networks is also facing some of the security issues faced by classical networks,such as how to ensure the reliable access of nodes in quantum communication networks.In the field of quantum security communications,although research results such as quantum authentication protocols,signature protocols,and key distribution protocols have been proposed,there are few studies on the trusted access aspects of nodes.In view of the above reasons,this paper takes the quantum communication network as the research background.Firstly,it analyzes many security problems in the structured quantum communication network based on trusted third parties.With the help of quantum entanglement,the decentralized pure distributed unstructured system is proposed.Quantum communication network;Secondly,it analyzes the security problems brought about by node access in the current quantum communication network,and proposes a strict authentication and credib ility evaluation for each newly added node,and proposes a node in the quantum communication network.Trusted evaluation model;Finally,by studying the security of node access in quantum communication network environment,using the quantum identity authentication and the trustworthy evaluation model of quantum nodes,a trusted access model for nodes in quantum communication networks based on entangled states is established.At the same time,the feasibility and security are analyzed and illustrated.This gives a new idea for the research on the trusted access of nodes in quantum communication networks.
