Quantum encryption microwave relay communication system and quantum encryption microwave relay communication method

Abstract

The invention discloses a quantum encryption microwave relay communication system and a quantum encryption microwave relay communication method. The system comprises a terminal station I, a relay station, and a terminal station II. The terminal station I is used for performing encryption operation on a key k with a key k1 to generate a key e1 and sending the key e1 to the relay station. The relay station is used for performing decryption operation on the key e1 with the key k1 to generate the key k, performing encryption operation on the key k with a key k2 to generate a key e2, and sending the key e2 to the terminal station II. The terminal station II is used for performing decryption operation on the key e2 with the key k2 to generate the key k. The key k1 is generated by the terminal station I and the relay station through a quantum key distribution terminal. The key k2 is generated by the terminal station II and the relay station through the quantum key distribution terminal. Finally, the terminal station I and the terminal station II have the same key k. The key k is relayed through the process. Through key relay transfer, transfer of the key k from the terminal station I to the terminal station II is realized.

Description

technical field

[0001] The present invention relates to a relay communication system and method, in particular to a quantum encryption microwave relay communication system and method. Background technique

[0002] Since the main mode of microwave communication is line-of-sight communication, relaying is required after the line-of-sight is exceeded. Generally speaking, due to the influence of the curved surface of the earth and the loss of space transmission, it is necessary to set up relay stations at certain distances to amplify and forward radio waves to extend them. This communication method is also called microwave relay communication or microwave relay communication. A complete long-distance transmission microwave system consists of terminal stations, hub stations, branch stations and several relay stations. Quantum optical free space transmission is also line-of-sight communication. When the loss of space transmission is too large, key relay is also required, such as ...
