Example Embodiment

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings:

[0030] The scene structure diagram used in the present invention is as follows figure 1 As shown, there are 4 modules including UAV, AWACS, satellite, and ground station:

[0031] UAVs are entities that perform specific tasks, and their specific applications include control reconnaissance, surveillance, search and rescue operations, and communication relays;

[0032] The early warning probability forms a fleet with several drones. The fleet is the basic unit for performing tasks. The drones can join or leave a certain fleet at will. As the central node of the fleet, it is responsible for managing the drones in the fleet. The relay node serves the drones in the fleet and can establish a safe link between the fleets;

[0033] Satellites mainly provide group management, key management and ultra-long-distance relay services for fleets. Its functions include registration ...

Abstract

The present invention discloses a method for establishing a secure communication link in a multi-UAV environment and mainly solves the problems that the link state is unstable and data is easily captured, deleted and even tampered by a third party due to frequent changes for a network topology in the existing Unmanned Aerial Vehicle (UAV) communication technology. The technical scheme of the present invention is as follows: satellites and Airborne Early Warning Aircrafts (AEW) are efficiently utilized to manage UAV nodes in terms of data transmission requirements for the UAV; a reliable link look-up and establishing method for the UAV communication is designed; a reliable interaction protocol is used when establishing the communication link so as to avoid the false communication requests and responses and prevent the link information from being tampered by malicious nodes; and data is encrypted with a private key allocated by a ground station so as to ensure the safety of messages and improve the stability and security for the UAV communication; meanwhile, the survivability of the system is enhanced by providing effective solutions for the condition of damaged link. The method provided by the invention can be used for establishing a secure communication link in a multi-UAV environment.

Description

technical field [0001] The invention belongs to the field of network communication, and relates to dynamic networking and network security technology, especially refers to a network system in which the network topology structure of unmanned aerial vehicle systems is not fixed, and wireless links are used between nodes, which can be used for safe communication between aviation flight equipment link establishment. Background technique [0002] With the development of UAV technology, it has a wide demand in electronic countermeasures, communication relay and other application fields. At present, UAVs still mainly work on a stand-alone basis. In countries around the world, UAVs generally use the rear ground control station to directly control single or multiple UAVs when performing tasks. It is a star-shaped control topology centered on the rear control center; however, as the times The tasks undertaken by UAVs are becoming more and more complex. A single UAV can no longer com...
