Idea
Platform detecting Blind DoS attacks in 5G networks using LLMs for real-time security.
Research Paper
Core Innovation
This paper introduces an LLM-based anomaly detection framework that operates in zero-shot mode using short natural language attack descriptions, overcoming the need for predefined rules or large training datasets. It integrates within the O-RAN architecture, ensuring compliance and real-time performance, and demonstrates superior detection quality driven by semantic completeness rather than description length or phrasing.
Why It Matters
Mobile networks face increasing security threats from Blind DoS attacks exploiting control-plane vulnerabilities, risking service quality and user experience. This solution enables real-time, explainable detection without extensive training data, improving network resilience and operational efficiency. It scales across evolving 5G and beyond infrastructures, supporting proactive defense.
