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…
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…
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…
