HELP: A Hardware-Embedded Delay PUF
Jim Aarestad, Philip Ortiz, Dhruva Acharyya, Jim Plusquellic · IEEE Design and Test · 2013
Physical Unclonable Functions enable a secure alternative method to traditional key storage and authentication schemes. This paper presents a novel PUF design that utilizes the existing path delays of a design to generate a random and stable bitstring of desired length with minimal area and performance overhead.
