Laboratory Security Evaluation of the OpenTitan Silicon Root of Trust

This post summarizes a joint hardware security evaluation of OpenTitan® engineering and production silicon by Fraunhofer AISEC in cooperation with design teams from Google, lowRISC® and Nuvoton.
The goal was to validate OpenTitan’s security under strong attack models before deployment in servers and Chromebooks. The evaluation analysed OpenTitan’s core security properties and led to several hardening measures and tooling improvements that benefit future tape-outs and deployments.
