XTRUST-6G is a Horizon Europe project building an end-to-end, zero-trust security framework for 6G networks. As 6G moves towards open, virtualised and AI-driven architectures such as O-RAN, both the attack surface and the long-term threat posed by quantum computing are growing significantly. XTRUST-6G responds with quantum-safe and intelligent security delivered as orchestrated services within the 6G and O-RAN infrastructure. At SnT, ��Vlog, the project develops two key technologies. The first turns quantum key distribution into an orchestrated, standards-compliant security service that provides resilient, quantum-safe key delivery to the 6G core and O-RAN. The second is an AI-driven physical-layer security module that protects the 6G wireless link against intelligent jamming, combining an adversarially robust neural receiver with real-time jamming detection and adaptive mitigation. Together, these technologies help ensure that critical 6G infrastructure remains secure, trustworthy and resilient against evolving cyber and quantum-enabled threats.
