Problems solved by technology

[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 the decryption process and reduces the reliability of the information
