Module: Physical Layer Security (40246)

About the Module

Security is a prerequisite of modern wireless communication systems and user services. In this course we will introduce a new security paradigm for communication systems, called physical layer security (PLS). PLS is an advanced method envisioned to meet the advanced requirements of future communication systems such as low latency ('fast security') and 'plug&secure' functionality. PLS is based on a well defined mathematical theory exploiting the inherent properties of the wireless channel, such as noise and fading. This module introduces information-theoretic foundations of PLS including the definition of secrecy capacity for the point-to-point wireless channel with an eavesdropper, as well as secret key agreement from stochastic channel measurements. Several potential deployment scenarios such as the Internet of Things will be discussed.
