K3Y Ltd authors a paper on “Trustworthy Analytics in ETSI ZSM: A 5G Security Case Study”

K3Y Ltd is proud to announce that the paper titled "Trustworthy Analytics in ETSI ZSM: A 5G Security Case Study" was published in IEEE Open Journal of the Communications Society: https://ieeexplore.ieee.org/document/10766438

The authors (Panagiotis Radoglou Grammatikis, Efklidis Katsaros, Evangelos Syrmos, Georgios P. Katsikas, Dimitrios Klonidis, Vasileios Argyriou, Thomas Lagkas and Panagiotis Sarigiannidis) explore how cross-domain storage, communication, and analytics services can enhance security within the 5G core. Specifically, the study examines the deployment of a User Plane Function (UPF) with AI-powered intrusion detection, ensuring its security before onboarding. The research models the attacker and defender strategies through a novel security game, where the attacker attempts to deceive the defender with adversarial attacks, while the defender leverages early detection and adversarial training to protect the AI models. In this security game, the Bayesian Nash equilibrium determines the optimal strategy for both attackers and defenders. Furthermore, experimental results demonstrate how cross-domain analytics can be utilized to assess AI security risks and enhance network resilience.
