Title: Physical layer security for 6G
Abstract: Physical-layer security (PLS) is increasingly regarded as a promising component of sixth-generation (6G) communication systems, owing to its potential to address stringent delay, power, and computational constraints. Motivated by these considerations, this talk pursues two main objectives. First, we revisit the fundamental security requirements for authentication and key agreement (AKA), and examine how these requirements can be translated into concrete PLS design goals. Second, we present novel AKA mechanisms that leverage trustworthy physical features—such as the angle of arrival in digital-array multiple-input multiple-output systems—as well as machine learning techniques to enable fast, low-overhead AKA protocols that are provably robust against both passive and active adversaries. Finally, we outline prospective use cases and research directions for PLS within emerging 6G networks.
