Research On Identity Authentication Of Quantum Communication LAN Based On Teleportation

Quantum information science is the combination of quantum mechanics and classical informatics emerging frontier science,in recent years, through such as Jian-wei Pan, Guang-can Guo those outstanding scientists work hardly in the field of quantum communication, Both of the theory and practice of quantum communication have been won a major breakthrough, meanwhile the information security of quantum communication has become one of the striking direction accordingly.In view of the present to the most quantum communication process may happen such as "fake identity attack" or "middle men attack" and so on problems about the communication security, this article based on the basic principles of quantum transmission and LAN classic communication authentication protocol and proposed the related authentication scheme about quantum communication and use the related theory of quantum transmission formula and unitary operation of identity authentication scheme had been done good validation and analysis.This article first from the wireless LAN and wired LAN communication network structure to analyze the types of features, then for quantum communications focuses on information transmission and the identity authentication scheme, in quantum communication network, using contact transmission principle research how to realize quantum communication user authentication scheme in network communication, to ensure the safety of network information transmission process.1) Because many users communicate with the same communication terminal certification at the same time, as the result of there is no clear priority level limit between users, at the same time ’blind competition for the same communication terminal authentication information caused by classical channel congestion, or in the network communication in static when idle.This article USES the token ring network working principle and recessive transmission, the combination of both to solve the priority level of user’s communication, but also can improve the user’s network security, this certification scheme mainly for each communication between sites in the token ring LAN implementation priority appointment and identity verification.In turn, to extend the scheme to the main line or star linear topological structure of network, so as to realize identity authentication in the quantum communication network.The biggest advantages of this solution: can be determined according to the circumstance of quantum communication network identity authentication and the order of the quantity, effectively avoid the conflict between communication users or idle waste of network resources.2) Based on wireless local area network(LAN) communication network, will contact transmission principle combined with the traditional communication Authentication Protocol to form a new Authentication scheme, quantum communication scheme for smaller first ESS(Extended Service Set), wireless local area network(LAN) structure is studied, and then according to the situation analysis further promote Extended to the whole network of quantum communication, quantum communication wireless network of EAP(Extensible Authentication Protocol) Authentication.In the wireless local area network(LAN), the client, the certification system and on the base of the EPR for the authentication Server, the client through the classical channel and quantum communication channel transmit the authentication information to the authentication Server, then the RS(Radius Server) to accept the authentication Server of quantum information and the corresponding classical information conversion, validated by the client to transmit information, and determine whether certification successfully.This identity authentication scheme of study provides a more free space quantum communication network security "firewall" protection technology, in order to further promote the practical application of quantum communication network provides the theoretical support.The meaning of this solution is that: by using the RS server control end user identity authentication in wireless local area network node AP, on the one hand can guarantee the communication security of the wireless local area network(wlan), on the other hand reflects the terminal access network node more conveniently and stably.
