N2 - Unmanned aerial vehicle (UAV) wireless communication has been considered to be a promising solution to provide ubiquitous coverage and enhanced capacity performance in the sixth-generation (6G) wireless networks. Against this background, safeguarding the UAV networks using physical layer security (PLS) techniques has been attracting significant research attention. In this chapter, we provide a comprehensive overview of PLS techniques in the UAV networks. Open problems and opportunities for PLS in the UAV networks are discussed. In addition, we take a UAV wiretap channel as an example and demonstrate how the design of the secure transmission scheme can effectively improve the secrecy performance of the considered UAV wiretap channel. To be more specific, we consider a UAV wiretap channel, in which a source communicates with a legitimate UAV in the presence of an eavesdropper. We assume the eavesdropper works in a full-duplex mode. That is, the eavesdropper is capable of performing both eavesdropping and malicious jamming at the same time. The source transmits artificial noise (AN) signals, along with information signals, to interfere with the eavesdropper. We derive the hybrid outage probability, which considers both the transmission outage probability and the secrecy outage probability. We also derive an analytical expression of the asymptotic hybrid outage probability in the regime where the transmit power becomes large. Through analysis and the simulation results, we show how the minimum hybrid outage probability can be achieved by adaptively adjusting the altitude of the UAV, and the power allocation between the AN signals and the information signals.
