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 investigates a physical layer authentication (PLA) scheme designed to overcome the limitations of traditional cryptographic approaches in large-scale and heterogeneous wireless networks, particularly for resource-constrained IoT devices. The proposed method introduces a reconciliation-based approach that leverages distributed source coding (Slepian-Wolf) with polar… Read More »Physical Layer Authentication Using Information Reconciliation
