This paper presents an improved framework for physical-layer authentication (PLA) in multiuser wireless environments, where channel variations, measurement noise, and interference can make it difficult to reliably distinguish legitimate users from attackers. Traditional CSI-based authentication methods often suffer in such… Read More »Enhanced Multiuser CSI-Based Physical Layer Authentication Based on Information Reconciliation

This paper presents a machine learning–driven localization framework that leverages Angle of Arrival (AoA) as a robust feature extracted from massive MIMO OFDM channel state information (CSI). The goal is to enable accurate user or device localization in complex outdoor… Read More »High-accuracy AoA-based Localization using Hierarchical ML Classifiers in Outdoor Environments

This paper investigates whether Angle of Arrival (AoA) can serve as a reliable feature for physical-layer authentication (PLA), particularly when an adversary attempts to impersonate a legitimate transmitter. While previous PLA methods often rely on features such as channel frequency… Read More »Leveraging Angle of Arrival Estimation against Impersonation Attacks in Physical Layer Authentication

This paper examines how future 6G networks—expected to function as large-scale cyber-physical systems—will require more advanced trust and reputation management mechanisms than those used today. As autonomous vehicles, drones, robots, and other intelligent agents collaborate in real time, the accuracy… Read More »A Framework for Global Trust and Reputation Management in 6G Networks
