Brief Report on QoSec, Context Aware Security and the Role of Physical Layer Security in 6G Wireless
Arsenia Chorti
While the security literature predominantly focuses on the core network, the enhancement of the security of the beyond fifth generation (B5G) access network becomes of critical imp…
5G New Radio Resource Allocation Optimization for Heterogeneous Services
Nasim Ferdosian, Sara Berri, Arsenia Chorti
5G new radio (NR) introduced flexible numerology to provide the necessary flexibility for multiplexing the communication of heterogeneous services on a shared channel. One of the f…
Multi-factor Physical Layer Security Authentication in Short Blocklength Communication
Miroslav Mitev, Mahdi Shekiba-Herfeh, Arsenia Chorti +1
Lightweight and low latency security schemes at the physical layer that have recently attracted a lot of attention include: (i) physical unclonable functions (PUFs), (ii) localizat…
Asymptotic Performance Analysis of NOMA Uplink Networks Under Statistical QoS Delay Constraints
Mouktar Bello, Arsenia Chorti, Inbar Fijalkow +2
In this paper, we study the performance of an uplink non-orthogonal multiple access (NOMA) network under statistical quality of service (QoS) delay constraints, captured through ea…
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…
Man-in-the-Middle and Denial of Service Attacks in Wireless Secret Key Generation
Miroslav Mitev, Arsenia Chorti, E. Veronica Belmega +1
Wireless secret key generation (W-SKG) from shared randomness (e.g., from the wireless channel fading realizations), is a well established scheme that can be used for session key a…
Denial of Service Attacks Detection in Software-Defined Wireless Sensor Networks
Gustavo A. Nunez Segura, Sotiris Skaperas, Arsenia Chorti +2
Software-defined networking (SDN) is a promising technology to overcome many challenges in wireless sensor networks (WSN), particularly with respect to flexibility and reuse. Conve…
Performance Analysis of NOMA Uplink Networks under Statistical QoS Delay Constraints
Mouktar Bello, Wenjuan Yu, Arsenia Chorti +1
In the fifth generation and beyond (B5G), delayconstraints emerge as a topic of particular interest, e.g. forultra-reliable low latency communications (URLLC) such asautonomous veh…
Flexible Multiple Access Enabling Low-Latency Communications: Introducing NOMA-R
Mouktar Bello, Wenjuan Yu, Mylene Pischella +3
Various verticals in 5G and beyond (B5G) networks require very stringent latency guarantees, while at the same time envisioning massive connectivity. As a result, choosing the opti…
Physical Layer Security: Authentication, Integrity and Confidentiality
Mahdi Shakiba-Herfeh, Arsenia Chorti, H. Vince Poor
The goal of physical layer security (PLS) is to make use of the properties of the physical layer, including the wireless communication medium and the transceiver hardware, to enabl…
Authenticated Secret Key Generation in Delay Constrained Wireless Systems
Miroslav Mitev, Arsenia Chorti, Martin Reed +1
With the emergence of 5G low latency applications, such as haptics and V2X, low complexity and low latency security mechanisms are sought. Promising lightweight mechanisms include…
