Physical unclonable function

A physical unclonable function, or PUF, is a physical object whose operation cannot be reproduced ("cloned") in a physical way (by making another system using the same technology), such that for a given input and conditions (challenge), provides a physically defined "digital fingerprint" output (response) that serves as a unique identifier—most often for…
