Intrinsic ID optimises SRAM PUF security technology

1 min read

Intrinsic ID, a provider of Physical Unclonable Function (PUF) security IP, has announced the new release of its flagship hardware IP product, QuiddiKey.

The release has been adapted to the needs of semiconductor designs targeting advanced process nodes. QuiddiKey 4.x provides additional security countermeasures, extended testability, and requires less non-volatile memory than previous versions.

“The need for trusted, transparent, and scalable security solutions in the semiconductor industry has never been greater,” said Pim Tuyls, CEO of Intrinsic ID. “Specialised applications in data centres, high-performance computing and artificial intelligence push computing limits and are driving the new features of QuiddiKey. The new product offers security IP that is future-proof and does not require redesign as process nodes keep shrinking and designs become more complex.”

QuiddiKey 4.x is the latest in a family of hardware IP solutions that enable chip designers to secure their silicon with internally generated, device-unique cryptographic keys. Using the inherently random start-up values of SRAM as a PUF, QuiddiKey generates the entropy required for a strong hardware root of trust by assuring that a device’s keys and sensitive data are never stored, but instead are re-created from the PUF each time they are needed.

Security solutions based on QuiddiKey are able to scale with the decrease in size of advanced technology nodes. This is because QuiddiKey uses SRAM to derive its cryptographic keys, which is a standard component available upon initial release of any process technology. This allows the Quiddikey IP to be used with any foundry and process node.

In addition, to further accommodate the needs of chip designers for small nodes, QuiddiKey 4.x also requires significantly less non-volatile data storage, as this type of storage can be scarce in advanced nodes.

QuiddiKey 4.x builds on previous releases of the product, which have been applied in a vast range of chips, from tiny microcontrollers to high-performance systems-on-chip. QuiddiKey IP has been validated for NIST CAVP and has been deployed and proven in more than 350 million devices, which have been certified by EMVCo, Visa, CC EAL6+, PSA, ioXt, and governments across the globe.
