Part of BMBF funded "6G Research and Innovation Cluster (6G-RIC)" under project identification number 16KISK020K (https://6g-ric.de/) with FUB focus on "Innovative Security Mechanisms and AI for 6G"

Joint project with 33 partners led by Fraunhofer HHI Berlin, until end 2025

In the overall 6G-RIC project, the FUB sub-project is investigating the key technologies of AI and post-quantum security with two focal points: i) post-quantum crypto and physical layer security ii) AI-based anomaly detection and demonstration of an AI engine

The first focus is on post-quantum secure codes that adapt to the propagation conditions in the radio field possibly with the help of intelligent, reflective surfaces or “secrecy maps”. This requires the development of robust methods for the characterization, measurement and even control of information-theoretical, and thus post-quantum secure security metrics. On the other hand, device-specific radio field and RF front-end parameters are used to derive a robust (radiometric) fingerprint. Here, too, robust methods for the algorithmic estimation of data protection and identity metrics must be developed on the basis of a fundamental information-theoretical analysis.

In the second focus area, AI-based anomaly detection methods for 6G networks are being investigated, with all layers being considered in principle. The sub-project pursues an innovative architecture approach in which the enormous amounts of data are distributed in the network (device, edge, cloud) and calculated using both central and local models, taking data protection into account. Within this distributed architecture, innovative methods for feature extraction, classification and detection are developed on the basis of generative models and finally combined with the federated approach in an ML engine. Finally, a software demonstrator for the ML engine will be developed, implemented and evaluated as a proof-of-concept within the 6G architecture of the overall project.
