Fabrication Begins for Production OpenTitan Silicon – Google Open Source Blog


OpenTitan is an open-source Root of Trust (RoT) project initiated by Google and developed with a community of partners to enhance device security.

In products composed of an interconnected jungle of hardware and software, like Chromebooks and our Cloud infrastructure, we rely on a small dedicated secure microcontroller called a Root of Trust (RoT). Open source is often the most economically efficient solution for developing foundational technology: it enables companies to work together and pool resources to build common, compatible products. Google and project partners – Nuvoton, ETH Zurich, G+D Mobile Security, lowRISC, Rivos, Seagate, Western Digital, Winbond, zeroRISC, and a number of independent contributors – provide open source hardware register-transfer level (RTL) and design verification (DV) code, along with integration guidelines, and reference firmware to drive adoption throughout industry.
