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,…
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…
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…
It Is Rude to Ask a Sensor Its Age-of-Information: Status Updates Against an Eavesdropping Node
Laura Crosara, Nicola Laurenti, Leonardo Badia
We consider periodical status updates between a transmitter and a legitimate receiver, in the presence of an eavesdropper that is sometimes able to capture pieces of information. W…
On the Limits of Cross-Authentication Checks for GNSS Signals
Francesco Ardizzon, Laura Crosara, Stefano Tomasin +1
Global navigation satellite systems (GNSSs) are implementing security mechanisms: examples are Galileo open service navigation message authentication (OS-NMA) and GPS chips-message…
On the Optimal Spoofing Attack and Countermeasure in Satellite Navigation Systems
Laura Crosara, Francesco Ardizzon, Stefano Tomasin +1
The threat of signal spoofing attacks against GNSS has grown in recent years and has motivated the study of anti-spoofing techniques. However, defense methods have been designed on…
