Secret Key Agreement with Physical Unclonable Functions: An Optimality Summary
Onur Günlü, Rafael F. Schaefer
We address security and privacy problems for digital devices and biometrics from an information-theoretic optimality perspective, where a secret key is generated for authentication…
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…
Low-complexity and Reliable Transforms for Physical Unclonable Functions
Onur Günlü, Rafael F. Schaefer
Noisy measurements of a physical unclonable function (PUF) are used to store secret keys with reliability, security, privacy, and complexity constraints. A new set of low-complexit…
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…
