ISAC-Assisted Channel Knowledge Map Generation for Physical Layer Authentication
Luca Bonaventura, Edoardo Gardin, Alessia Barison +2
Integrated sensing and communication (ISAC) enables the acquisition of environmental information by leveraging wireless signals transmitted for communication purposes. In this pape…
Physical Layer Authentication With Channel Knowledge Maps in Indoor Environments
Luca Bonaventura, Francesco Ardizzon, Stefano Tomasin
Physical layer authentication (PLA) allows to authenticate the user by comparing measurements over time, assuming their time consistency or by modeling their evolution. However, th…
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…
Physical Layer-Based Device Fingerprinting for Wireless Security: From Theory to Practice
Junqing Zhang, Francesco Ardizzon, Mattia Piana +2
The identification of the devices from which a message is received is part of security mechanisms to ensure authentication in wireless communications. Conventional authentication a…
Learning The Likelihood Test With One-Class Classifiers for Physical Layer Authentication
Francesco Ardizzon, Stefano Tomasin
In physical layer authentication (PLA) mechanisms, a verifier decides whether a received message has been transmitted by a legitimate user or an intruder, according to some feature…
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…
