Physically Unclonable Function (PUF) Enhancements Via Lithography and Design Partnership

Associate Professor Ankur Srivastava (ECE/ISR) is the principal investigator of a three-year, $500K hardware security grant from the National Science Foundation for “Physically Unclonable Function (PUF) Enhancements Via Lithography and Design Partnership.” A silicon physically unclonable function (PUF) is a supplemental circuit embedded in an IC which generates signatures unique to its native IC. This research investigates fundamentally different approaches to PUF enhancements. It leverages quantified models for fabrication randomness that have been developed in design for manufacturability related research endeavors.
