SUNNYVALE, Calif., March 23, 2022 – Intrinsic ID, the world’s leading provider of non-clonable physical function (PUF) security IP, today announced that its flagship hardware IP product, QuiddiKey®, is now compatible with the OpenTitan Root of Trust (RoT) interface ). OpenTitan is an open source project that makes the design and implementation of RoT silicon more transparent, reliable, and secure for enterprises, platform vendors, and end users.

A RoT is a component that can always be trusted within a cryptographic system and forms the basis of the system’s security architecture. It ensures that basic operations are performed securely, such as booting a device and storing confidential information and cryptographic keys, thereby establishing a basic level of trust in the system.

OpenTitan is the first collaborative open-source silicon project to build transparent, high-quality reference design and integration guidelines for hardware RoTs. The project is administered by lowRISC and is a collaboration between multiple partners – including Google, Western Digital, Seagate and others – to produce high-quality open IP for instantiation as a full product. Designers using OpenTitan RoT technology benefit from its transparency, quality and flexibility. As an open source design, OpenTitan can be inspected and evaluated by anyone, and is vendor and platform independent.

“The development of the OpenTitan family of IPs, including the Ibex RISC-V core and other blocks that connect to it, is a community effort,” said Gavin Ferris, CEO of lowRISC. “We are pleased to see companies like Intrinsic ID working to make their technology compatible with OpenTitan, grow its ecosystem, and help address the pressing need for reliable, transparent, and portable security solutions in the semi industry. -drivers.”

“At Intrinsic ID, we recognize the value OpenTitan offers as a reliable and fully transparent RoT. That is why we are pleased to announce that QuiddiKey now comes with an interface that is fully compatible with OpenTitan,” said Pim Tuyls , CEO of Intrinsic ID. “The integration was a straightforward effort for our engineering team, as OpenTitan’s open source framework and publicly available documentation provided all the information required for the task. Now any designer using the OpenTitan architecture OpenTitan can easily integrate PUF-based key storage into its designs to further increase the strength of its hardware security.

QuiddiKey IP can be applied easily to almost any chip – from tiny microcontrollers to high-performance SoCs, to secure products with internally generated, device-unique cryptographic keys. It uses the inherently random boot values ​​of SRAM as PUFs, which generates the entropy required for strong hardware RoT. Since SRAM is a standard component available during the initial release of any process technology, IP can be used with any foundry and process node technology. QuiddiKey has been deployed and proven on hundreds of millions of devices and has successfully passed certifications from NIST, EMVCo, Visa, CC EAL6+, PSA, ioXt and governments around the world.
