Wireless communication has already had a transfor-mative impact on lifestyles, as well as the way of interacting andcommunicating, throughout many years. This transformation isaccelerated by technological drivers such as Artificial Intelligence(AI) as well as the ever-increasing demand for bandwidth andthroughput. However, it is already foreseeable that the FifthGeneration (5G) cellular networks will not be sufficient to copewith the volume of mobile communication in 2030 and beyond.This paper considers Beyond 5G (B5G) and Sixth Generation(6G) mobile communications and outlines challenges for them.Alongside the technical requirements, the security, confidentialityand trustworthiness are of major importance. Therefore, thepaper discusses the various 6G research areas such as VisibleLight Communication (VLC), Reconfigurable Intelligent Surfaces(RISs) and (sub)Terahertz (THz) communication and highlightshow the research areas contribute to Physical Layer Security(PhySec) and how the development of 6G will act as catalyst forPhySec.
