Embodiments of the present invention provide a method, system and device for detecting spoofing attacks of UAVs, the method including: receiving a plurality of information to be processed; according to the first position of the UAV when receiving each information to be processed, and The second position of the ground base station connected by the UAV and the transmission power of the ground base station determine the theoretical received signal strength value of each message to be processed; calculate the actual received signal strength value of each message to be processed and the theoretical received signal strength value The absolute value of the difference is used as the signal strength error value corresponding to the information to be processed; whether there is attack information in multiple information to be processed is detected, and the attack information is the information to be processed whose corresponding signal strength error value is greater than the preset error threshold; if If there is attack information, it is determined that the UAV is subjected to a spoofing attack. The accuracy of detecting spoofing attacks of drones is improved by the above method.
Description
technical field [0001] The invention relates to the technical field of UAV communication, in particular to a method, system and device for detecting spoofing attacks of UAVs. Background technique [0002] With the rapid advancement of science and technology, drone technology is developing rapidly. Due to its high flexibility and other advantages, UAVs have been widely used in many fields. For example, UAVs can be used as air BS (Base Station, base station), which can provide reliable and cost-effective wireless communication to the required area. In addition, the unmanned aerial vehicle can also coexist with the ground user equipment and be used as an aerial UE (User Equipment, user equipment) called a cellular unmanned aerial vehicle. Due to the openness of the wireless environment, when the UAV is used as an air UE, the UAV is similar to the ground user equipment. When communicating with the GCS (Ground Control Station, ground base station), it is vulnerable to malicious...
