Towards a Multi-Layer Defence Framework for Securing Near-Real-Time Operations in Open RAN
Hamed Alimohammadi, Samara Mayhoub, Sotiris Chatzimiltis +2
Securing the near-real-time (near-RT) control operations in Open Radio Access Networks (Open RAN) is increasingly critical, yet remains insufficiently addressed, as new runtime thr…
Interpretable Anomaly-Based DDoS Detection in AI-RAN with XAI and LLMs
Sotiris Chatzimiltis, Mohammad Shojafar, Mahdi Boloursaz Mashhadi +1
Next generation Radio Access Networks (RANs) introduce programmability, intelligence, and near real-time control through intelligent controllers, enabling enhanced security within…
KPI Poisoning: An Attack in Open RAN Near Real-Time Control Loop
Hamed Alimohammadi, Sotiris Chatzimiltis, Samara Mayhoub +4
Open Radio Access Network (Open RAN) is a new paradigm to provide fundamental features for supporting next-generation mobile networks. Disaggregation, virtualisation, closed-loop d…
Surviving the Storm: The Impacts of Open RAN Disaggregation on Latency and Resilience
Sotiris Chatzimiltis, Mohammad Shojafar, Mahdi Boloursaz Mashhadi +1
The development of Open Radio Access Networks (Open RAN), with their disaggregated architectures and virtualization of network functions, has brought considerable flexibility and c…
