Abstract: Physical layer security is a promising approach that can benefit traditionalencryption methods. The idea of physical layer security is to take advantage ofthe features of the propagation medium and its impairments to ensure securecommunication in the physical layer. This work introduces a comprehensivereview of the main information-theoretic metrics used to measure the secrecyperformance in physical layer security. Furthermore, a theoretical frameworkrelated to the most commonly used physical layer security techniques to improvethe secrecy performance is provided. Finally, our work surveys physical layersecurity research over several enabling 5G technologies, such as massivemultiple-input multiple-output, millimeter-wave communications, heterogeneousnetworks, non-orthogonal multiple access, and full-duplex. Also, we include thekey concepts of each of the aforementioned technologies. Future fields ofresearch and technical challenges of physical layer security are alsoidentified.
