SRAM PUF-based key provisioning system to secure IoT

February 14, 2017 // By Julien Happich
Intrinsic ID's newly announced CITADEL is an SRAM Physical Unclonable Function (PUF)-based key provisioning system, delivered in a package that includes hardware or software IP, manufacturing tools and an OEM management suite.

These features come bundled in a new business model that incentivizes companies to implement security across their entire product portfolios without having to make a choice between security and the margin pressures in the IoT market.

CITADEL relies on Intrinsic ID's unique SRAM PUF technology to generate root keys internally from silicon, minimizing the liabilities in the supply chain. Any sensitive material on the chip is fully protected by keys derived from the invisible SRAM PUF root key. Since the root keys are internally generated, secure provisioning can take place at any point in the supply chain. This gives an OEM the opportunity to tighten its "Trust Silo" and puts it in complete control of provisioning without requiring an expensive infrastructure. CITADEL can leverage Intrinsic ID's BROADKEY, which is powered by SRAM PUF in software, so essentially any chip can have a unique secret key or ID. This capability enables CITADEL users to quickly take advantage of the growing ecosystem being built around chip-to-cloud authentication.

With CITADEL, Intrinsic ID claims it has created the world's first provisioning system that easily scales both in cost and technology, addressing the needs of IoT.
