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…
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…
Smart Channel State Information Pre-processing for Joint Authentication and Secret Key Distillation
Muralikrishnan Srinivasan, Sotiris Skaperas, Arsenia Chorti +3
While the literature on RF fingerprinting-based authentication and key distillation is vast, the two topics have customarily been studied separately. In this paper, starting from t…
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…
Deep Learning Based Detection for Spectrally Efficient FDM Systems
David Picard, Arsenia Chorti
In this study we present how to approach the problem of building efficient detectors for spectrally efficient frequency division multiplexing (SEFDM) systems. The superiority of re…
Rate Analysis and Deep Neural Network Detectors for SEFDM FTN Systems
Arsenia Chorti, David Picard
In this work we compare the capacity and achievable rate of uncoded faster than Nyquist (FTN) signalling in the frequency domain, also referred to as spectrally efficient FDM (SEFD…
Scheduling Optimization of Heterogeneous Services by Resolving Conflicts
Sotiris Skaperas, Nasim Ferdosian, Arsenia Chorti +1
Fifth generation (5G) new radio introduced flexible numerology to provide the necessary flexibility for accommodating heterogeneous services. However, optimizing the scheduling of…
Performance Analysis of Uplink NOMA-Relevant Strategy Under Statistical Delay QoS Constraints
Mylene Pischella, Arsenia Chorti, Inbar Fijalkow
A new multiple access (MA) strategy, referred to as non orthogonal multiple access - Relevant (NOMA-R), allows selecting NOMA when this increases all individual rates, i.e., it is…
Real-Time Video Content Popularity Detection Based on Mean Change Point Analysis
Sotiris Skaperas, Lefteris Mamatas, Arsenia Chorti
Video content is responsible for more than 70% of the global IP traffic. Consequently, it is important for content delivery infrastructures to rapidly detect and respond to changes…
