wolfSSL and OpenTitan: Securing the Open Silicon Era

wolfSSL is initiating support for OpenTitan, the open-source silicon Root of Trust. Our implementation will integrate with OpenTitan’s hardware accelerators, specifically the OpenTitan Big Number (OTBN) unit, AES, and HMAC/KMAC blocks, to offload cryptographic operations from the host RISC-V core. This integration provides a transparent, FIPS-ready security stack for embedded designs.

The programmable OTBN unit enables efficient execution of Post-Quantum Cryptography (PQC). We aim to support accelerated lattice-based algorithms, including ML-DSA (Dilithium) and ML-KEM (Kyber), directly on the hardware. This architecture addresses requirements for the EU Cyber Resilience Act and FIPS 140-3 standards without reliance on proprietary security modules.

We are gauging user interest to prioritize specific features. If you are developing on OpenTitan Earl Grey or the integrated Darjeeling architecture, let us know your requirements. Contact facts@wolfssl.com to register interest and shape the roadmap.

If you have questions about any of the above, please contact us at facts@wolfssl.com or call us at +1 425 245 8247.
