The Life of a Token: from Words to Bits on the Wire
Davide Avesani, Pengwenlong Gu, Sotiris Skaperas +1
Large Language Models (LLMs) transform vast collections of unstructured text into semantic patterns used for language generation and reasoning tasks. Behind their ease of use lies…
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…
An Open-Source Experimentation Framework for the Edge Cloud Continuum
Georgios Koukis, Sotiris Skaperas, Ioanna Angeliki Kapetanidou +2
The CODECO Experimentation Framework is an open-source solution designed for the rapid experimentation of Kubernetes-based edge cloud deployments. It adopts a microservice-based ar…
ClusterSlice: A Zero-touch Deployment Platform for the Edge Cloud Continuum
Lefteris Mamatas, Sotiris Skaperas, Ilias Sakellariou
We demonstrate ClusterSlice, an open-source solution for automated Kubernetes-center deployments for the edge continuum. ClusterSlice is an infrastructure-as-a-service, platform-as…
A Pragmatical Approach to Anomaly Detection Evaluation in Edge Cloud Systems
Sotiris Skaperas, George Koukis, Ioanna Angeliki Kapetanidou +2
Anomaly detection (AD) has been recently employed in the context of edge cloud computing, e.g., for intrusion detection and identification of performance issues. However, state-of-…
