Silicon root of trust (RoT) technology is important for embedding security mechanisms at silicon level for a wide range of products from mobile devices to network cards to webscale servers. It is increasingly important as fears about 5G and cloud security rise, but it is also highly proprietary to each equipment vendor. To address that issues, an open source project called OpenTitan says it will produce a reference design and integration guidelines for silicon RoT. Although Google is a leading figure in the group, and its own RoT design is called Titan, OpenTitan will not be an open source version of that technology. All participants will co-develop a design from scratch that will be agnostic to platform and vendor, said…
