APPLICATION OF A PERMUTATION DECODING METHOD IN A SMALL-CLASS UNMANNED AERIAL VEHICLE CONTROL SYSTEM (DRONES, MULTICOPTERS)

This paper analyzes the theory of control of unmanned aerial vehicles. Permutation decoding tools have been found to allow masking of the actual signal structure for a short period of time. Cyber espionage and data leakage are common practices, and this can immediately influence the security of these complex machines. Cyber-attacks, network vulnerability, malware attacks to steal data from special projects, as well as unmanned aircraft technology are among the most desirable targets. This article will examine the ability of an attacker transmitting falsified GPS signals that affect the behavior of an autonomous UAV. The requirements for an open and hidden capture of the UAV navigation system were presented along with the results of live tests of fake attacks against several commercial GPS receivers. When analyzing the related dynamics of the UAV and spoofing, it was shown that the GPS spoofing attack can force the UAV to unconsciously follow the trajectory imposed by the trigger mechanism. The strict upper limit of the UAV reference acceleration trajectory was shown to lead to the construction of the Spoofer example of stealth testing based on innovation. Finally, field testing showed that a destructive GPS spoofing attack on a rotary-wing UAV is both technically and efficiently feasible. The demonstration is a proof of the concept of a simple special case in a wide class of GPS spoofing attacks on mobile targets.
