Communication link encryption system and encryption method suitable for unmanned aerial vehicle

Abstract

The invention discloses a communication link encryption system and encryption method suitable for an unmanned aerial vehicle. An unmanned aerial vehicle end encryption system comprises an unmanned aerial vehicle end data transmission module used for sending data to a ground end equipment encryption system and receiving data from the ground end equipment encryption system; the unmanned aerial vehicle end key database module is used for storing or changing a key; the unmanned aerial vehicle end encryption module is used for encrypting or decrypting the unmanned aerial vehicle end data through the secret key; the ground end encryption system comprises a ground end data transmission module used for sending data to the unmanned aerial vehicle end equipment encryption system and receiving data from the unmanned aerial vehicle end equipment encryption system; the ground end key management module is used for generating, storing or changing a key; and the ground end encryption module is used for encrypting or decrypting the ground end data through the secret key. The communication link encryption system suitable for the unmanned aerial vehicle is simple in link and high in decryption accuracy.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle communication control, and more specifically relates to a communication link encryption system and encryption method suitable for unmanned aerial vehicles. Background technique [0002] During the flight test, the UAV needs to keep in touch with the ground at any time, subject to the limitation of the operating speed of the UAV equipment, common encryption algorithms such as the Advanced Encryption Algorithm (AES) become inapplicable due to the time-consuming encryption; at the same time The security of information between UAV-side equipment and ground-side equipment is becoming more and more important in communication. Different encryption methods on the communication link increase the security of information, but multiple encryption methods that are independent of each other and exist at the same time will increase the The complexity of the link increases the risk of errors in th...
