Guardtime, Intrinsic-ID Deliver Blockchain IoT Device Identity & Security

Guardtime 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 defense customers, as well as telecom operators rolling out smart city solutions in energy, health care and transportation.

According to the partners, 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.
