Quantum secret data chain communication system

Abstract

The invention discloses a quantum secret data link communication system, which comprises two identical quantum secrecy devices, each quantum secrecy device comprises quantum key generation equipment, a key management control server and a plurality of secrecy terminals, wherein each key management control server is bound with a plurality of confidential terminals; the two pieces of quantum key generation equipment are used for transmitting the partial normal single light quantum through a channel, operating a BB84 protocol and generating symmetrical quantum keys; putting into respective key pools; then respectively issuing to the secret key management control servers which are respectively connected with the server; the key management control server is used for receiving and verifying the quantum key issued by the key pool and then distributing the quantum key to a plurality of bound confidential terminals; and the security terminal is used for establishing a binding connection with the key management control server through a built-in authentication key, and receiving and storing the quantum key. The system disclosed by the invention has the advantages of high security, high independence, and convenience, rapidness and simplicity in deployment.

Description

technical field [0001] The present invention relates to the field of secure communication / communication technology, in particular to a quantum secure data link communication system. Background technique [0002] As more and more traditional manual services are replaced by online electronic services, such as the rise of online banking, online tax declaration, online securities and other services, it indicates that the construction of my country's information superhighway has entered a stage of vigorous development. Encryption technology, authentication technology, digital signature and many other technical problems need to be solved urgently, among which the status of information cipher and security is particularly prominent. Quantum cryptography, based on the uncertainty principle and the indivisibility of single photons, has become the most secure encryption method at present, with unlimited application prospects. The research of quantum cryptography provides a technical g...

AI Technical Summary

Problems solved by technology

[0011] The current quantum secure communication network is mainly a wired network based on optical fiber, and its application layer is a closed wired protection subnet, and its ease of use is greatly limited. At present, there is no practical and feasible solution for using quantum keys on portable terminals.
