Trustworthiness and Sustainability for 6G

The European research project COREnext aims to build a computing architecture and components for sustainable and trustworthy B5G and 6G processing. B5G stands for "Beyond 5G," which refers to the next generation of wireless communication networks that will come after 5G.

The initiative brings together 23 European partners from ten different countries to build together a trustworthy-by-design computing platform for 6G flagship use cases to consolidate European digital sovereignty and unlock a new economic perspective.

Barkhausen Institut takes on the responsibility of overall project coordination of 23 partners, while also involved in the technical development. We participate in defining the overall digital architecture of future mobile networks to ensure that our notion of trust by isolation is reflected. To advance the processing capabilities, we contribute our M³ platform, which can integrate energy-efficient accelerators into a system-on-chip together with a system platform designed for trustworthiness.

The computing architecture that COREnext is working on must support an open, multi-vendor and multi-tenant disaggregated RAN (Radio Access Network) by employing virtualization technology. That means the system design must be flexible enough to work with different computing devices that are connected over the network. Multiple applications should be able transparently access these devices while still being strongly isolated from each other.

A step forward in digital component design must be made to increase the speed and to create highly energy-efficient computer systems. This is addressed by the development of powerful and efficient heterogeneous accelerators, purpose-built for RAN computation and signal processing. In addition, ultra-high-speed and low-power interconnects will be engineered to separate computing resources so that they can work independently and efficiently.

A cornerstone of the project is trustworthiness. The pervasiveness of B5G and 6G use cases requires deeply embedded hardware trust anchors to enable secure disaggregated compute systems. To realize these goals, the project brings together major telecommunications and microelectronics players as well as academic research partners. A strategic roadmap will offer a transparent path towards future exploitation of the generated research results, fostering a continuing European strategy for the emergence of European digital capabilities in this communication-computing domain.

The project is funded by the European Union.
