Embodiment Construction

[0013] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0014] In one of the embodiments, the present invention proposes a communication encryption method between the UAV and the ground station, such as figure 1 As shown, the method includes the following steps:

[0015] The S1 ground station sends control commands to the UAV;

[0016] The S2 UAV verifies the control command, and sends the UAV ID to the ground station after the verification is passed;

[0017] The S3 ground station receives the UAV ID, verifies the UAV ID, sends a data request to the UAV after the verification is passed, and exposes the public key of the ground station to the UAV;

[0018] After the S4 UAV receives the data request and the ground station public key, it generates a session key, encrypts the session key and the return data with the ground station public key, and sends the encrypted sess...

Abstract

The invention relates to a method for encrypting the communication between a UAV (unmanned aerial vehicle) and a ground station. The method comprises the steps that the ground station sends a controlcommand to the UAV; the UAV verifies the control command, and after verification succeeds, the UAV sends a UAV ID to the ground station; the ground station verifies the UAV ID, after verification succeeds, the ground station sends a data request to the UAV, and reveals a ground station public key to the UAV; the UAV receives the data request and the ground station public key, then generates a session key, encrypts the session key and returned data by using the ground station public key, then packs and sends the encrypted session key and returned data to the ground station; and the ground station performs decryption according to a ground station private key. According to the method, data transmitted between the UAV and the ground station is encrypted based on an asymmetrical encryption method, uplink data and downlink data between the UAV and the ground station are guaranteed to be transmitted in a form of ciphertext, so that the UAV is prevented from being controlled maliciously and data is prevented from being stolen and being used illegally, and communication between the UAV and the ground station is safer.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a communication encryption method between an unmanned aerial vehicle and a ground station. Background technique [0002] With the development of drone technology, drones have been widely used in aerial photography, safety inspections, and agricultural operations. They have the advantages of flexible deployment, precise operation, high efficiency and environmental protection, and can save a lot of labor costs. At present, the communication between the drone and the ground station is basically not encrypted. Once the drone is maliciously captured and disassembled, it is very easy to counterfeit the control information, and it is also easy to cause the data to be stolen and embezzled. . Contents of the invention [0003] Based on this, it is necessary to provide a communication between the UAV and the ground station to solve the problem that the current communica...
