Abstract: Physical layer security techniques exploit the inherent randomness of wireless medium for information security, but which has been significantly challenged by the rapid development and evolvement of the fifth generation of mobile communications system (5G). The research and application of physical layer security techniques in 5G wireless networks was reviewed from three aspects:the joint investigation of physical layer security techniques and the new transmission techniques, the security enhancement schemes under emerging network scenarios, and the countermeasure design against the new threats in 5G wireless networks. Based on the survey of the latest researches in these areas, the open issues and future research directions were discussed.

Key words: the fifth generation of mobile communications system, physical layer security, mmWave
