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
Matteo Varotto, Stefan Valentin, Stefano Tomasin
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…
