Physical layer security (PLS) offers a promising alternative to traditional cryptographic methods, particularly for resource-constrained devices such as IoT sensors. However, secret key generation (SKG) techniques typically rely on channel variations caused by mobility—making them less effective in low-mobility or… Read More »Enhancing Secret Key Generation in Low-Mobility Scenarios by Locally Generated Pilots

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
