Abstract

This paper describes a technique that exploits the statistical delay variations of wires and transistors across ICs to build a secret key unique to each IC. To explore its feasibility, we fabricated a candidate circuit to generate a response based on its delay characteristics. We show that there exists enough delay variation across ICs implementing the proposed circuit to identify individual ICs. Further, the circuit functions reliably over a practical range of environmental variation such as temperature and voltage.
