Physical Layer Anomaly Detection via Adaptive Gaussian Mixture Model
Mamady Delamou, Luan Chen, Arsenia Chorti
Physical-layer spoofing attacks pose a critical threat to wireless localization systems by manipulating channel state information (CSI). Detecting such attacks becomes particularly…
Near-Field Physical-Layer Authentication Under Impersonation Attacks
Hajar El Hassani, Linda Senigagliesi, Arsenia Chorti
This paper studies physical-layer authentication (PLA) in the near-field regime under impersonation attacks. Unlike the far-field case, where the steering vector depends only on th…
Channel Chart Location Privacy Based on Geo-Indistinguishability
Atsu Kokuvi Angélo Passah, Rodrigo C. de Lamare, Arsenia Chorti
Channel charting enables location-based services (LBSs) without requiring explicit position information by using pseudo-locations from the channel chart. While this property implie…
Adaptive Learning Strategies for AoA-Based Outdoor Localization: A Comprehensive Framework
Bac Trinh-Nguyen, Sara Berri, Sin G. Teo +2
Localization in 5G and 6G networks is essential for important use cases such as intelligent transportation, smart factories, and smart cities. Although deep learning has enabled im…
On the Robustness of AoA as an Authentication Feature Under Spoofing: Fundamental Limits from Misspecified Cramer Rao Theory
Sotiris Skaperas, Arsenia Chorti
The robustness of angle of arrival (AoA) as a physical layer authentication (PLA) feature under spoofing attacks is studied, assuming a digital uniform linear array verifier. The v…
Misspecified Crame-Rao Bound for AoA Estimation at a ULA under a Spoofing Attack
Sotiris Skaperas, Arsenia Chorti
A framework is presented for analyzing the impact of active attacks to location-based physical layer authentication (PLA) using the machinery of misspecified Cramér--Rao bound (MCR…
