On the Robustness of AoA as an Authentication Feature Under Spoofing: Fundamental Limits from Misspecified Cramer Rao Theory
Sotiris Skaperas, Arsenia Chorti
The robustness of angle of arrival (AoA) as a physical layer authentication (PLA) feature under spoofing attacks is studied, assuming a digital uniform linear array verifier. The v…
Misspecified Crame-Rao Bound for AoA Estimation at a ULA under a Spoofing Attack
Sotiris Skaperas, Arsenia Chorti
A framework is presented for analyzing the impact of active attacks to location-based physical layer authentication (PLA) using the machinery of misspecified Cramér--Rao bound (MC…
Channel State Information Preprocessing for CSI-based Physical-Layer Authentication Using Reconciliation
Atsu Kokuvi Angelo Passah, Rodrigo C. de Lamare, Arsenia Chorti
This paper introduces an adaptive preprocessing technique to enhance the accuracy of channel state information-based physical layer authentication (CSI-PLA) alleviating CSI variati…
Secret Key Generation Rates for Line of Sight Multipath Channels in the Presence of Eavesdroppers
Amitha Mayya, Arsenia Chorti, Rafael F. Schaefer +1
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 foc…
Physical Layer Authentication Using Information Reconciliation
Atsu Kokuvi Angélo Passah, Rodrigo C. de Lamare, Arsenia Chorti
User authentication in future wireless communication networks is expected to become more complicated due to their large scale and heterogeneity. Furthermore, the computational comp…
