Aircraft air-ground communication method and module, aircraft and medium

Abstract

The invention discloses an aircraft air-ground communication method and module, an aircraft and a medium, and is applied to a communication module of the aircraft, and the method comprises the steps: obtaining a random challenge number sent by a server, and obtaining communication configuration information of a session with a ground station based on the random challenge number, the communication configuration information at least comprising end point information of the ground station; establishing a secure connection with the ground station based on the endpoint information; initializing a dual-domain architecture based on the secure connection; obtaining an execution instruction sent by the ground station based on the air-ground communication domain; and based on the built-in domain, transmitting the execution instruction to a processor for security verification, and after the processor verifies that the execution instruction passes, executing a target execution action corresponding to the execution instruction. According to the method, the isolation of the communication domain and the built-in domain is realized through the double-domain architecture, and the security and reliability of instruction transmission are ensured; and meanwhile, the processor is used for performing security verification on the execution instruction, so that the communication security of the aircraft is improved.
