| Abstract: | The high mobility of Unmanned Aerial Vehicles (UAVs) can be utilized to meet requirements of the next-generation communication networks such as high coverage and low latency, while due to the broadcast nature of wireless channels and the increasing number of nodes, the problem of secure transmission also needs to be urgently addressed. Since UAVs are resource-constrained aerial platforms, upper-layer encryption techniques can hardly play an equally effective role in UAV communication networks. The essence of physical layer security is to design artificially the communication channel so as to maximize the difference between the legitimate and eavesdropping channel, and the application of physical layer security technology to UAV communication networks can assist to achieve a compromise between confidential transmission and energy efficiency. This paper reviews the current researches on physical layer security transmission technology of UAV communication networks. Specifically, typical physical layer security transmission technologies are firstly introduced in scenarios, and then the challenges in their applications into UAV communication networks are analyzed. Finally, new scenarios, technologies, and methods for the development of physical layer security transmission technologies in UAV communication networks are prospected to provide a new perspective for the research on physical layer security transmission technology of UAV communication networks. |
