IoT Blockchain Security from Intrinsic-ID and Guardtime

Guardtime, platform for ensuring the integrity of data and systems, and embedded authentication company Intrinsic-ID have announced they are to co-operate to deliver customer solutions combining Intrinsic-ID’s SRAM Physical Unclonable Functions (PUFs) and Guardtime’s Keyless Signature Infrastructure (KSI) blockchain technology, providing scalable security and governance for the Internet of Things.

A series of pilots will be conducted in order to showcase customer security solutions, leveraging Intrinsic-ID’s SRAM PUF-based key management system, and Guardtime’s KSI Blockchain. The initial focus is on mission assurance for defence customers, as well as telecom operators rolling out smart city solutions in energy, health care and transportation.

Matthew Johnson, Guardtime CTO, said: “Having worked with PUF technologies over the last 15 years, I’m convinced that Intrinsic-ID is the first company to successfully industrialize the technology and bring it to the mainstream. We are extremely excited to be working with the team at Intrinsic-ID and look forward to building solutions that solve hard customer problems.”

Intrinsic-ID CEO, Pim Tuyls commented: “We are thrilled to be working with Guardtime to integrate PUF technology with Guardtime’s KSI Blockchain. The combination of PUF technology and Blockchains represents a new level of security and governance for customers who wish to deploy IOT devices at scale.”

By using PUF Technology to uniquely authenticate a device and registering that device with ownership information on a ledger, the provenance and integrity of every piece of data generated by that device can be cryptographically proven and linked back to an authenticated device with end to end chain of custody. In this way the data integrity and authentication perimeter is extended all the way to the silicon chips where the data originates.
