QCMI-Based Quantum Markov Blanket Discovery for Semantic Quantum Networks
Evangelos K. Markakis, Ilias Politis
Quantum-enabled semantic communication networks (QESCs) leverage quantum technologies to transmit data meaning efficiently, yet face challenges from costly resources and noise. Thi…
eBPF-Based Cybersecurity Mechanisms: A Systematic Literature Review
Stamatios Kostopoulos, Panagiotis Tsakonas, Evangelos K. Markakis
Extended Berkeley Packet Filter (eBPF) has emerged as a kernel-level framework enabling dynamic security enforcement in modern operating systems. While eBPF's cybersecurity potenti…
From Graphs to Gradients: Physics-Inspired Structural Attribution for Cyber-Physical IoT Systems and Beyond
Spyridon Evangelatos, Christos Diou, Georgios Th. Papadopoulos +2
Interpretable explanation methods in Artificial Intelligence aim to uncover the underlying causes and their effects, enabling a deeper understanding of why a system behaves in a ce…
Human Vulnerability Assessment in Cybersecurity: A Systematic Literature Review of Methods, Models, and Instruments
Dimitra Papatsaroucha, Stavroula Psaroudaki, Eleftheria Vassilaki +4
In cybersecurity, vulnerability assessment has typically focused on identifying and measuring vulnerabilities within digital assets and technical infrastructures. However, there is…
Kernel-Based ReLU Approximation for Homomorphic Encryption-Compatible Privacy-preserving Deep Learning Models
Dimitrios Sygletos, Dimitra Papatsaroucha, Marios Choudetsanakis +2
As privacy concerns in AI technologies continue to grow, Homomorphic Encryption (HE) offers a way to perform computations on encrypted data without the need of decryption during op…
Foundation Models in Robotics: A Comprehensive Review of Methods, Models, Datasets, Challenges and Future Research Directions
Aggelos Psiris, Vasileios Argyriou, Evangelos K. Markakis +5
Over the recent years, the field of robotics has been undergoing a transformative paradigm shift from fixed, single-task, domain-specific solutions towards adaptive, multi-function…
The Decentralisation Paradox in Digital Identity: Centralising Decentralisation with Digital Wallets?
Ioannis Konstantinidis, Ioannis Mavridis, Evangelos K. Markakis
Digital identity is shifting from service- and network-centric approaches toward user-centric ones that promise users increased control over their data. Despite their decentralised…
Pool Formation in Oceanic Games: Shapley Value and Proportional Sharing
Aggelos Kiayias, Elias Koutsoupias, Evangelos Markakis +1
We study a game-theoretic model for pool formation in Proof of Stake blockchain protocols. In such systems, stakeholders can form pools as a means of obtaining regular rewards from…
Malware Detection in Docker Containers: An Image is Worth a Thousand Logs
Akis Nousias, Efklidis Katsaros, Evangelos Syrmos +7
Malware detection is increasingly challenged by evolving techniques like obfuscation and polymorphism, limiting the effectiveness of traditional methods. Meanwhile, the widespread…
An impossibility result for strongly group-strategyproof multi-winner approval-based voting
Ioannis Caragiannis, Rob LeGrand, Evangelos Markakis +1
Multi-winner approval-based voting has received considerable attention recently. A voting rule in this setting takes as input ballots in which each agent approves a subset of the a…
Blockchain Participation Games
Pyrros Chaidos, Aggelos Kiayias, Evangelos Markakis
We study game-theoretic models for capturing participation in blockchain systems. Permissionless blockchains can be naturally viewed as games, where a set of potentially interested…
