Abstract [eng] The purpose of the final master’s thesis was to analyse in as much detail as possible the possibility of breaching the control of a single layer UAV swarm by using an electronic attack. The object of the study is an UAV swarm consisting of 10 agents, i.e. 9 slaves and one master. The swarm is fully autonomous - it has no direct contact with the human factor throughout the mission. The architecture of the UAV swarm is analysed in this work. It has been determined in what way the UAV swarm agents do not collide and maintain the structure. To determine the vulnerability of an UAV swarm, it is important to identify all possible communications between swarm agents and the communication architecture. The Ad-hock communication architecture has been chosen to investigate in more detail. It has been chosen to use an UAV swarm in the study which consists of 9 slaves and 1 master This configuration is used because of the clarity of the control algorithms and to test the accuracy and applicability. Several control algorithms have been developed to represent the simulation data. To test the accuracy of the control algorithms, one simulation without a swarm leader is presented and it is found that the precision of this algorithm is more than 99 %. Based on the STRIDE methodology, security threats to UAV swarms in the FANET are identified. The 4 UAV swarm communication links have 6 potential threats in cyberspace and the 2 nodes have 6 threats to themselves. A software architecture based on Linux software has been developed and a cyber-attack against the assumed leader of the UAV swarm has been performed. It was noticed that the DoS attack radically changed the movement trajectory of the assumed leader. Research has shown that UAV swarms use an open network to communicate. An algorithm for a distributed FANET connection method was developed based on the choice of a leader in an open network of one or more frequency bands. An electronic attack model based on probability equations has been developed. The model is applied to an unspecified control system and is based on vulnerability conditions that are defined when the attacker aircraft connects to the swarm network architecture.
