This paper analyzes a new attack strategy targeting challenge–response physical layer authentication (CR-PLA) systems that rely on intelligent reflecting surfaces (IRSs). The authors extend prior KL-divergence–based bounds for conventional PLA to the CR-PLA setting, where Bob randomizes the IRS phase… Read More »Divergence-Minimizing Attack Against Challenge-Response Authentication with IRSs
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
In this paper, the feasibility of implementing a lightweight key distribution scheme using physical layer security for secret key generation (SKG) is explored. Specifically, we focus on examining SKG with the received signal strength (RSS) serving as the primary source… Read More »Secret Key Generation Rates for Line of Sight Multipath Channels in the Presence of Eavesdroppers
