Thee Role of AI in 6G Security

AI brings cognition to thee network edge. Instad of reacting after a breach, AI systems can continuously monitor traffic, user behavor, and device health tu preempt attacks. The core capabilities fall into several domains.

Real- Czas Anomalii Detection

AI models, particularly deep learning and graph neural networks, can analyze packet-level flows and application-layer interactions at line rate. By learning the ‘normal’ traffic patterns across thousands of slices and services, these systems flag deviations—such as unusual inter-arrival times, unexpected protocol headers, or anomalous routing paths—in real time. For example, a 6G base station serving a smart factory might see a sudden spike in control commands from a non-authenticated source; an AI-driven security agent would quarantine that session within microseconds, preventing a potential sabotage of industrial robots.

Adaptive Access Control

Static uwierzytelniation (np., passwords or certificates) is inquident in dynamic 6G environments. AI enables continuos certification bye fusing multiple signals: biometrics, device fingerprints, geolocation, behavoral Patterns, and radio frequency (RF) signures. Machine lening models can assign a risk score to every acquirs requesto and adaft permissions in real time.
