Description

Technical Field

[0001] The invention belongs to the technical field of surveying and mapping space data processing, and in particular relates to a method and device for removing false information from low-altitude unmanned aerial vehicles. Background Art

[0002] In recent years, with the development of drone technology and the reduction of costs, drones have been applied in more and more fields. Low-altitude unmanned aerial vehicles, as the application of drones at low altitudes (below 200m), have also had a negative impact on people's daily lives and brought huge challenges to the management of business and military.

[0003] In order to supervise low-altitude unmanned aerial vehicles, it is necessary to report the flight data of the aircraft to the supervision system. One way of reporting data is that the low-altitude unmanned aerial vehicle can broadcast the data, and the ground collection equipment receives the broadcast data and then reports the data to the supervision system through the network. However, this method will bring the risk of forging flight data and then forging false targets. These false data and false targets will greatly affect the decision-making of the system and affect the accuracy and effectiveness of supervision.

[0004] Currently, there is a way to solve this problem, which is to use radar / laser / infrared and other means to detect pseudo targets, and report the detected data to the supervision system. The supervision system will also receive the flight data, and then compare the two phases of data in terms of location, characteristics, etc. to filter out pseudo targets. This method can effectively remove some pseudo targets. However, this method has the following problems:

[0005] (1) High cost. This method requires the deployment of radar / laser / infrared and other hardware facilities, which is very expensive.

[0006] (2) Low efficiency. This method compares data obtained by two different methods and requires a lot of processing. The efficiency of removing false targets is very low, and it is difficult to effectively remove false targets. Summary of the invention

[0007] The present invention aims to provide a method and device for removing counterfeit of low-altitude unmanned aerial vehicles to improve the above-mentioned problem.

[0008] The method for removing fake low-altitude unmanned aerial vehicles comprises the following steps:

[0009] Step 1: Add a low-altitude unmanned aerial vehicle to the system. The parameters include at least the unique number of the low-altitude unmanned aerial vehicle. The system generates a corresponding authentication key based on the unique number of the low-altitude unmanned aerial vehicle.

[0010] Step 2: Use the tool to communicate with the low-altitude unmanned aerial vehicle and obtain its unique number;

[0011] Step 3: The tool sends a request to the system with the unique number of the low-altitude unmanned aerial vehicle as a parameter to obtain the low-altitude unmanned aerial vehicle authentication key;

[0012] Step 4: After the tool obtains the authentication key, it communicates with the low-altitude unmanned aerial vehicle again and writes the authentication key into the low-altitude unmanned aerial vehicle;

[0013] Step 5: When the low-altitude unmanned aerial vehicle generates data, it generates a digital signature together with the unique number of the low-altitude unmanned aerial vehicle, the data and the authentication key, and the data and the signature are packaged into one piece of data and broadcasted;

[0014] Step 6: When the ground acquisition device receives the broadcast data, it obtains the unique number of the low-altitude unmanned aerial vehicle from the data, and then sends a request to the system with the unique number of the low-altitude unmanned aerial vehicle as a parameter to obtain the authentication key of the low-altitude unmanned aerial vehicle;

[0015] Step 7: The ground collection equipment verifies whether the data, authentication key, and digital signature match. If they match, the data is real; if they do not match, the data is fake.

[0016] Step 1, add a remote identification module to the supervision system; the remote identification module's unique number is its serial number. When adding a remote identification module, at least the serial number should be filled in. This system also fills in the remote identification module model, the bound drone manufacturer, model, and drone fuselage information;

[0017] In step 5, the flight data is encrypted with the authentication key and then a digital signature is generated using the SM3 algorithm. Then the remote identification module serial number, flight data, digital signature and other parameters are assembled according to the RemoteID specification, and the assembled data is broadcasted via WiFi or Bluetooth.

[0018] In step 7, the ground collection equipment encrypts the original flight data using the authentication key, generates a digital signature using the SM3 algorithm, and then verifies whether the digital signature broadcast by the remote identification module matches the digital signature. If they match, the data is authentic and is reported to the regulatory system. If they do not match, the data is forged and is not reported.

[0019] A low-altitude unmanned aerial vehicle anti-counterfeiting device is also provided, which is used to implement the low-altitude unmanned aerial vehicle anti-counterfeiting method, comprising:

[0020] Ground collection equipment is a device for receiving data broadcast by the device, used to receive the data broadcast by the device, and connected to the system through the network to communicate with the system;

[0021] The system is a low-altitude monitoring system used to manage equipment information, ground collection equipment information, and key information;

[0022] The tool is an APP or PC tool that communicates with the device through WiFi, Bluetooth, or serial port to obtain device data. It also connects to the system through the network to communicate with the system.

[0023] Beneficial effects of this method:

[0024] The present invention uses digital signature authentication, generates a digital signature at the low-altitude unmanned aerial vehicle end, and verifies the digital signature at the ground collection device. Forged data can only reach the ground collection device at most, and cannot reach the supervision system, thereby reducing the reporting of forged data. The system server needs to process less data, reduces the pressure on the server, and also reduces interference with the system's decision-making, making low-altitude supervision more efficient and accurate.
