By bringing its world-renowned hardware evaluation expertise to the world’s first open-source silicon Root of Trust (RoT), Fraunhofer will play a critical role in independently validating the project's resilience against advanced physical and logical attacks. OpenTitan, stewarded by the not-for-profit lowRISC®, relies on a transparent, community-driven methodology to build commercial-grade secure silicon designs. While open-source transparency allows for widespread code inspection, true hardware security also demands rigorous, specialized physical testing. Fraunhofer AISEC’s Common Criteria (CC)-certified Hardware Security Lab will provide exactly that, offering cutting-edge evaluations including side-channel analysis, fault injection testing, and secure boot verification. “Radical transparency in silicon design only achieves its full potential when paired with ruthless, independent testing,” said Javier Orensanz Martinez, CEO of lowRISC. “Fraunhofer AISEC is globally respected for its deep expertise in applied hardware security and physical attack mitigation. Having them join the OpenTitan coalition as a dedicated testing partner ensures that the OpenTitan open-source Root of Trust can confidently withstand the most sophisticated attacks in the wild.” As a security testing partner, Fraunhofer will collaborate with the OpenTitan coalition to evaluate the physical resilience of the project's silicon designs, such as the Earl Grey top level. By analyzing and testing the hardware architecture before and after tape-out, Fraunhofer will help the community refine its countermeasures, harden its cryptographic accelerators (including early integration of post-quantum cryptography), and ensure the design meets the highest evaluation assurance levels.

The evaluation analysed OpenTitan’s core security properties and led to several hardening measures and tooling improvements that benefit future tape-outs and deployments of the OpenTitan silicon root-of-trust. “We strongly believe that open-source hardware is a vital component for the future of technological sovereignty and trusted electronics,” stated Prof. Dr. Georg Sigl, Institute Director at Fraunhofer AISEC. “OpenTitan represents a paradigm shift in how secure silicon is developed. We are thrilled to apply our comprehensive spectrum of offensive hardware security analyses to this project, ensuring that the open-source community's innovations are matched by uncompromising physical robustness. With the additional high-end lab‑equipment investment made possible by initiatives like APECS and Trusted Electronic Bavaria Center (TrEB), which support applied research in trusted electronics, we can broaden our security‑analysis portfolio and extend it to cover emerging System-on-chips and chiplet technologies.” Fraunhofer joins a rapidly growing and distinguished OpenTitan coalition.
