Security, Privacy, and Safety Aspects of Civilian Drones

Abstract

The market for civilian unmanned aerial vehicles, also known as drones, is expanding rapidly as new applications are emerging to incorporate the use of civilian drones in our daily lives. On one hand, the convenience of offering certain services via drones is attractive. On the other hand, the mere operation of these airborne machines, which rely heavily on their cyber capabilities, poses great threats to people and property. Also, while the Federal Aviation Administration NextGen project aims to integrate civilian drones into the national airspace, the regulation is still a work-in-progress and does not cope with their threats. This article surveys the main security, privacy, and safety aspects associated with the use of civilian drones in the national airspace. In particular, we identify both the physical and cyber threats of such systems and discuss the security properties required by their critical operation environment. We also identify the research challenges and possible future directions in the fields of civilian drone security, safety, and privacy. Based on our investigation, we forecast that security will be a central enabling technology for the next generation of civilian unmanned aerial vehicles.
