Cyber Research Hub · NATO NSPA

Role: Key Lead (SnT – SIGCOM / 6GSPACE Lab)
Funding & Partnership: Cyber Research Hub (Luxembourg Directorate of Defence & University of Luxembourg) in collaboration with the NATO Support and Procurement Agency (NSPA)
Official Announcement: NSPA and University of Luxembourg Announce Joint Project to Support NATO’s Anti-Jamming Activities (nspa.nato.int)

Executive Summary

CRH WARRIOR is a strategic defense research project initiated under the Cyber Research Hub partnership between the Luxembourg Directorate of Defence and the University of Luxembourg (SnT), executed in collaboration with the NATO Support and Procurement Agency (NSPA). The project strengthens NATO’s anti-jamming capabilities in satellite communications (SATCOM) and uncrewed aerial systems (UAS), including critical missions operated by the NATO Intelligence, Surveillance and Reconnaissance Force (NISRF) RQ-4D Phoenix fleet.

Key Objectives & Technical Contributions

Adaptive AI Anti-Jamming at Allied Ground Stations: Developing real-time artificial intelligence and machine learning models hosted at ground stations to detect, classify, geolocate, and counteract rapidly evolving dynamic jamming attacks.
Operational SATCOM & UAS Resilience: Combining SIGCOM / 6GSPACE Lab’s satellite signal processing expertise with NATO operational scenarios to protect command-and-control (C2) and high-rate telemetry links.
Hardware-in-the-Loop Validation: Experimental validation on the 6GSPACE Lab RF spectrum monitoring and software-defined radio (SDR) testbeds.

SENTINEL – Uplink JCAS for Jamming Detection & Geolocation in LEO NTN

Wed, 01 Jan 2025 00:00:00 +0000

FNR Luxembourg

Role: Co-Principal Investigator (SnT – SIGCOM / 6GSPACE Lab)
Funding: FNR Joint Call Defense (with OQ Technology)
Official Page: uni.lu/snt-en/research-projects/sentinel/

Executive Summary

SENTINEL is a defense research project funded under the FNR Joint Call Defense programme in partnership with OQ Technology. The project leverages Joint Communications and Sensing (JCAS) on 5G-NTN Low Earth Orbit (LEO) satellite uplinks to detect, classify, and geolocate malicious interference sources and authenticate legitimate ground terminals.

Key Objectives & Contributions

Uplink Jammer Detection & Geolocation: Real-time sensing of broadband uplink jammers, reactive PRACH jammers, and pilot spoofing attacks from LEO payloads.
Motion-Adaptive 5D Physical Authentication: Exploiting spatial, temporal, frequency (Doppler), delay, and polarization signatures to verify terminal authenticity under high-mobility satellite passes.

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

Wed, 01 May 2024 00:00:00 +0000

Horizon Europe SNS JU

Role: Pilot 4 Lead (SnT – SIGCOM / 6GSPACE Lab)
Funding: European Commission (Horizon Europe Smart Networks and Services Joint Undertaking – SNS JU)
Official Page: uni.lu/snt-en/research-projects/xtrust-6g/

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.
