Secure Transmission in IRS-Assisted MIMO Systems with Active Eavesdroppers
Ali Bereyhi, Saba Asaad, Ralf R. Müller +2
This work studies secure transmission in intelligent reflecting surfaces (IRS)-assisted MIMO systems when an active eavesdropper is available in the network. We consider a scenario…
Shannon Meets Turing: Non-Computability and Non-Approximability of the Finite State Channel Capacity
Holger Boche, Rafael F. Schaefer, H. Vincent Poor
The capacity of finite state channels (FSCs) has been established as the limit of a sequence of multi-letter expressions only and, despite tremendous effort, a corresponding finite…
Neural Mutual Information Estimation for Channel Coding: State-of-the-Art Estimators, Analysis, and Performance Comparison
Rick Fritschek, Rafael F. Schaefer, Gerhard Wunder
Deep learning based physical layer design, i.e., using dense neural networks as encoders and decoders, has received considerable interest recently. However, while such an approach…
Randomized Nested Polar Subcode Constructions for Privacy, Secrecy, and Storage
Onur Günlü, Peter Trifonov, Muah Kim +2
We consider polar subcodes (PSCs), which are polar codes (PCs) with dynamically-frozen symbols, to increase the minimum distance as compared to corresponding PCs. A randomized nest…
Biometric and Physical Identifiers with Correlated Noise for Controllable Private Authentication
Onur Günlü, Rafael F. Schaefer, H. Vincent Poor
The problem of secret-key based authentication under privacy and storage constraints on the source sequence is considered. The identifier measurement channels during authentication…
