Secure communication is expected to become even more critical in future 6G networks, particularly as emerging technologies such as quantum computing threaten traditional public-key encryption schemes. To explore alternative security approaches, researchers have developed a context-aware secret key generation (SKG)… Read More »Context-Aware Secret Key Generation Demonstrator based on Physical Layer Security

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
