FedSwitch: Federated Region Classification From Wireless Channel Measurements
Mattia Piana, Stefano Rini, Stefano Tomasin
Wireless Internet-of-Things (IoT) networks can leverage locally observed channel state information (CSI) at base-stations (BSs) to perform region classification, i.e., infer the re…
From Identification to Authentication for Micro-CSI RF Fingerprinting in OFDM Systems
Matteo Varotto, Stefano Tomasin
We consider a scenario where a legitimate user (Alice) authenticates itself to an authenticator (Bob) by transmitting orthogonal frequency division multiplexing (OFDM) pilots, from…
Model-Driven Learning-Based Physical Layer Authentication for Mobile Wi-Fi Devices
Yijia Guo, Junqing Zhang, Yao-Win Peter Hong +1
The rise of wireless technologies has made the Internet of Things (IoT) ubiquitous, but the broadcast nature of wireless communications exposes IoT to authentication risks. Physica…
Lightweight Pilot Estimation on LEO Satellite Signals for Enhanced SOP Navigation
Francesco Zanirato, Alessio Curzio, Francesco Ardizzon +5
The computation of positioning, navigation and timing (PNT) via signal of opportunity (SOP), where signals originally transmitted for communication, such as 5G, Wi-Fi, or DVB-S, ar…
Jamming Detection in Cell-Free MIMO with Dynamic Graphs
Ali Hossary, Laura Crosara, Stefano Tomasin
Jamming attacks pose a critical threat to wireless networks, particularly in cell-free massive MIMO systems, where distributed access points and user equipment (UE) create complex,…
VBSF: A Visual-Based Spam Filtering Technique for Obfuscated Emails
Ali Hossary, Stefano Tomasin
Recent spam email techniques exploit visual effects in text messages, such as poisoning text, obfuscating words, and hidden text salting techniques. These effects were able to evad…
Hybrid Channel- and Coding-Based Challenge-Response Physical-Layer Authentication
Laura Crosara, Mahtab Mirmohseni, Stefano Tomasin
This letter proposes a new physical layer authentication mechanism operating at the physical layer of a communication system where the receiver has partial control of the channel c…
Authentication by Location Tracking in Underwater Acoustic Networks
Gianmaria Ventura, Francesco Ardizzon, Stefano Tomasin
Physical layer message authentication in underwater acoustic networks (UWANs) leverages the characteristics of the underwater acoustic channel (UWAC) as a fingerprint of the transm…
Challenge-Response to Authenticate Drone Communications: A Game Theoretic Approach
Mattia Piana, Francesco Ardizzon, Stefano Tomasin
As drones are increasingly used in various civilian applications, the security of drone communications is a growing concern. In this context, we propose novel strategies for challe…
Performance Limits for Signals of Opportunity-Based Navigation
Francesco Zanirato, Francesco Ardizzon, Laura Crosara +4
This paper investigates the potential of non-terrestrial and terrestrial signals of opportunity (SOOP) for navigation applications. Non-terrestrial SOOP analysis employs modified C…
Detecting 5G Signal Jammers Using Spectrograms with Supervised and Unsupervised Learning

Cellular networks are potential targets of jamming attacks to disrupt wireless communications. Since the fifth generation (5G) of cellular networks enables mission-critical applica…
One-Class Classification as GLRT for Jamming Detection in Private 5G Networks
Matteo Varotto, Stefan Valentin, Francesco Ardizzon +2
5G mobile networks are vulnerable to jamming attacks that may jeopardize valuable applications such as industry automation. In this paper, we propose to analyze radio signals with…
Energy-Based Optimization of Physical-Layer Challenge-Response Authentication with Drones
Francesco Ardizzon, Damiano Salvaterra, Mattia Piana +1
Drones are expected to be used for many tasks in the future and require secure communication protocols. In this work, we propose a novel physical layer authentication (PLA)-based c…
Detecting 5G Narrowband Jammers with CNN, k-nearest Neighbors, and Support Vector Machines
Matteo Varotto, Florian Heinrichs, Timo Schuerg +2
5G cellular networks are particularly vulnerable against narrowband jammers that target specific control sub-channels in the radio signal. One mitigation approach is to detect such…
