XTRUST-6G

This pilot integrates Quantum Key Distribution (QKD) with 6G networks to provide quantum-resistant encryption for end-to-end communications. It aims to manage the key rate and encryption flow across various 6G components, maintaining performance without compromising security. The pilot will take place at the University of Luxembourg’s campuses (Belval and Kirchberg), testing these technologies within a secure academic infrastructure. As traditional key exchange and encryption protocols become increasingly vulnerable, QKD offers a quantum-secure channel resistant to computationally unbounded attackers. The pilot addresses key challenges such as secure authentication, seamless key distribution, and efficient key relay mechanisms. SNT will use its Quantum Lab, 6GSpaceLab, and QKD infrastructure to design, implement, and validate QKD integration within 6G networks. The setup includes a QKD star topology with iDQ XGR devices, interconnected via dedicated dark fibers, and a 5G+/6G testbed using open-source core networks and software-defined radios.
