Sicherheit auf der Übertragungsschicht 2

In this course we will learn more advanced topics in physical layer security, continuing the discussion from the lecture Physical Layer Security 1. More specifically, the sequential key distillation for secret key generation, strong secrecy, privacy issues tackled by physical layer schemes, and the more general setting where the eavesdropper is active.

Content:

• Review of information theory and physical layer security
• Sequential key distillation
• Gaussian wiretap channel with multiple antennas: the optimal input distribution
• Fading channels, ergodic and outage capacities, and artificial noise design
• Strong secrecy
• Privacy: differential privacy, stealth and covert communications, private information retrieval, wireless privacy
• Finite block length analysis and wiretap code implementations
• Active attacker

Latest Information

We will have an introduction of the lectures and tutorials on Thuesday, 20.10.2020  11:30 - 13:00.
Additionally, we will discuss the procedure throughout the semester.
The procedure will be as follows.

We will upload videos of the lectures and the tutorials at the corresponding time (lectures on Thuesdays, tutorials on Wednesdays every second week). Following this approach, you are able to watch the videos as you like. We will ask the you to send us your questions with respect to the lectures and tutorials throughout the semester. Here again, we will prepare videos answering those questions and upload them together with the next lecture/tutorial video. At the end of the semester we are planning to have a BlueButton event in order to clarify all remaining questions in preparation of the examination.

Latest Information regarding the lecture and excercise can be found at StudIP, too.
