Abstract
In recent years, due to rapid advances in science and technology and the continuous reduction of manufacturing costs, unmanned aerial vehicles (UAVs) have expanded from the military field to the civil field and are used in a variety of scenarios. However, while bringing convenience to people, the security problems with UAVs are becoming more and more obvious. It is therefore critically important to take the cybersecurity of UAVs into account. In the present paper, we introduce the composition structure and various applications of the UAVs, and analyze the research status of UAV cybersecurity. Then we discuss the cybersecurity issues faced by UAVs from the aspects of confidentiality, integrity and availability. In particular, the vulnerability analysis technologies used in the UAV software systems are introduced. At last, the future research directions of UAV cybersecurity are discussed.
