講座內容：

This tutorial is on a new family of physical-layer security technologies for future wireless networks. The physical-layer security (PLS) is a promising concept to complement the cryptographic technologies at upper layers in wireless networks. Various channel-based approaches, e.g., secret-key extraction, directional modulation, and artificial-noise injection, have been conceived to exploit wireless channel characteristics in providing PLS. Recently, legitimate channel-gain-mapped sources have been developed to constitute a novel technology of the physical-layer secret key generation, referred to as metasource-based secret key (MBSK). In contrast to the channel-based approaches, the MBSK technology not only promotes the actual realisation of the PLS concept but also induces green communications for future wireless networks. This tutorial introduces the MBSK technology through discussing its design principles, the latest advantages, the challenges, and the road ahead in the research. Our hope is to facilitate researchers who might have interests in the PLS concept would like to kick-start their understanding of recently developed techniques in the MBSK realm.
