Quantum secure communication system

Abstract

The invention discloses a quantum secure communication system. The system comprises a quantum random number generator, a key management and distribution server and a plurality of quantum secure terminals, wherein the plurality of quantum security terminals are bound with the key management and distribution server; the quantum random number generator is used for generating a quantum true random number as a quantum key for secret communication and sending the quantum key to a key management and distribution server; the key management and distribution server is used for controlling the quantum random number generator and is also used for receiving the quantum key and safely issuing the quantum key to the plurality of quantum secret terminals; and the quantum security terminal is used for establishing a binding connection with the distribution server through the built-in authentication key and key management, and receiving and storing the quantum key. In the system provided by the invention, the quantum key is locally distributed to the communication terminal through the single quantum random number generator and the quantum key management and distribution server, the system is simple, and the security is reliable.

Description

technical field [0001] The invention belongs to the field of secure communication, and in particular relates to a quantum secure communication system. Background technique [0002] The basic process of data encryption is to process the original text and the encryption key with a certain algorithm to obtain an unreadable code, which is the ciphertext, which is the encryption process. When the ciphertext is transmitted to the recipient through the network, the recipient can convert the ciphertext into the original plaintext content through the decryption key and the inverse operation of the encryption algorithm, which is the decryption process. Whether it is encryption or decryption, a lot of computing work is involved. [0003] At present, cryptographic systems are divided into two types: symmetric and asymmetric. If the encryption key and the decryption key are the same, it is a symmetric cryptosystem. The technology is characterized by open algorithms and high encryption...

Problems solved by technology

[0010] 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.
