XTRUST-6G – AI-Driven Physical Layer Security & O-RAN Zero-Trust (Pilot 4)

Role: Pilot 4 Lead (SnT – SIGCOM / 6GSPACE Lab)
Funding: European Commission (Horizon Europe Smart Networks and Services Joint Undertaking – SNS JU)

Executive Summary

Within the XTRUST-6G Horizon Europe SNS JU project, the 6GSPACE Lab at SnT leads Pilot 4 on AI-Driven Physical Layer Security and Zero-Trust O-RAN Resilience. The activity develops real-time AI/ML defenses at the radio physical layer and Open RAN Near-Real-Time RAN Intelligent Controller (Near-RT RIC) to protect 6G terrestrial, UAV, and non-terrestrial links against smart jamming and adversarial waveforms.

Key Objectives & Contributions

• Adversarial-Resilient Neural Receivers: Deep-learning physical layer receivers hardened against protocol-aware and adversarial RF attacks.
• Near-RT RIC Security xApps: Real-time interference classification, physical-layer key generation, and automated spectrum/beam mitigation via O-RAN E2 interfaces.
