Nuvoton introduces the first security chip based on OpenTitan open-source silicon Root of Trust

OpenTitan demo board Nuvoton open source security chip

Google has announced the start of the fabrication of a Nuvoton security chip featuring OpenTitan open-source silicon Root of Trust (RoT), the first such production-ready chip. It will soon be available in lowRISC’s Voyager 1 demo board, and later this year in Chromebooks and data centers. We first wrote about OpenTitan open-source Root of Trust (RoT) chips in 2020 as a collaboration between Google, Seagate, Nuvoton, Western Digital, lowRISC, as well as some other companies, projects, and universities that aimed at “building a transparent, high-quality reference design and integration guidelines for silicon root of trust (RoT) chips”. OpenTitan itself reached commercial availability last year, after the first engineering samples were released in 2023, and Google now says the Nuvoton chip (yet to have a proper name) is the first production-ready OpenTitan chip. Hardware Root of Trust (RoT) are small secure microcontrollers that are the equivalent of Certificate Authorities (CAs) to […]
