Intrinsic PUF to support blockchain security

EE Times Europe | By Graham Prophet
Embedded hardware security company Intrinsic-ID BV (Sunnyvale, Calif.) has agreed to combine its SRAM-based Physical Unclonable Function (PUF) technology with Keyless Signature Infrastructure (KSI) blockchain technology from GuardTime (Tallinn, Estonia).

Guardtime and Intrinsic-ID will conduct a series of pilots 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.
