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 (MCR…
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…
Physical Layer Security for 6G Systems why it is needed and how to make it happen
Arsenia Chorti
Sixth generations (6G) systems will be required to meet diverse constraints in an integrated ground-air-space global network. In particular, meeting overly aggressive latency const…
Distributed DoS Attack Detection in SDN: Trade offs in Resource Constrained Wireless Networks
Gustavo A. Nunez Segura, Arsenia Chorti, Cintia Borges Margi
The Software-defined networking(SDN) paradigm centralizes control decisions to improve programmability and simplify network management. However, this centralization turns the netwo…
Comparison of Short Blocklength Slepian-Wolf Coding for Key Reconciliation
Mahdi Shakiba-Herfeh, Arsenia Chorti
We focus Slepian-Wolf (SW) coding in the short blocklength for reconciliation in secret key generation and physical unclonable functions. In the problem formulation, two legitimate…
