Anomaly Detection for Sensing Security
Stefan Roth, Aydin Sezgin
Various approaches in the field of physical layer security involve anomaly detection, such as physical layer authentication, sensing attacks, and anti-tampering solutions. Dependin…
A Structural Analysis of the User Behavior Dynamics for Environmentally Sustainable ICT
Stefan Roth, Aydin Sezgin
The sector of information and communication technology (ICT) can contribute to the fulfillment of the Paris agreement and the sustainable development goals (SDGs) through the intro…
EMF-Constrained Artificial Noise for Secrecy Rates with Stochastic Eavesdropper Channels
Stefan Roth, Aydin Sezgin
An information-theoretic confidential communication is achievable if the eavesdropper has a degraded channel compared to the legitimate receiver. In wireless channels, beamforming…
Localization Attack by Precoder Feedback Overhearing in 5G Networks and Countermeasures
Stefan Roth, Stefano Tomasin, Marco Maso +1
In fifth-generation (5G) cellular networks, users feed back to the base station the index of the precoder (from a codebook) to be used for downlink transmission. The precoder is st…
Remote Short Blocklength Process Monitoring: Trade-off Between Resolution and Data Freshness
Stefan Roth, Ahmed Arafa, H. Vincent Poor +1
In cyber-physical systems, as in 5G and beyond, multiple physical processes require timely online monitoring at a remote device. There, the received information is used to estimate…
On The Efficiency of Widely Linear Precoding and Symbol Extension in Cellular Uplink
Ali Kariminezhad, Stefan Roth, Aydin Sezgin +1
We investigate Gaussian widely linear precoding known as improper Gaussian signaling for the cellular uplink with inter-cell interference, known as interference multiple access cha…
