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…
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…
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…
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…
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…
