Advances and Rethinking of Physical Layer Security Technologies

ABSTRACT

Physical layer security technologies, built upon device and channel characteristics, possess uniqueness and non-clonability. Compared to traditional upper-layer security technologies, they offer higher security, lower overhead, and greater compatibility. In wireless communication or mobile network environments, they even exhibit the "one-time pad" perfect secrecy characteristic. This talk begins by introducing the classification of existing physical layer security technologies, their respective assumptions, and their advantages and disadvantages, including physical layer authentication, physical layer covert communication, physical layer key generation, physical layer low probability detection, and physical layer anti-eavesdropping. The talk then focuses on innovative algorithms for physical layer authentication technologies, followed by an introduction to the application extensions of these technologies. Finally, it discusses future research prospects in physical layer security technologies.
