Signalverarbeitung am Kanaleingang für sichere Übertragungen über Fast-Fading-Kanäle mit statistischer Kanalkenntnis am Sender
Zusammenfassung der Projektergebnisse
In this project we have investigated several topics in physical layer security. The first and the most important one is about the fast fading wiretap channel with statistical CSIT. We partly solve the open problem on the ergodic secrecy capacity by deriving a sufficient condition on the fading distributions of the legitimate’s and the eavedropper’s channel gains. We later form a framework and use it to prove the ergodic capacity regions of Gaussian interference channels with strong and very strong interferences, binary interference channels with weak and strong interferences, and also Gaussian broadcast channels. All are with statistical CSIT. The same framework is also used to prove the stealthy secret key capacity under Maurer’s satellite model. During this project, we also investigated code generation for Gaussian wiretap channel by the neural network and also the secrecy energy efficiency for broadcast and interference channels with confidential messages. We also investigated the physical layer privacy by merging the concepts from physical layer security and the secrecy from computer science, i.e., the differential privacy and the receiver message unlinkability.
