Physical unclonable function
Unreproducible object used in digital security
A physical unclonable function, or PUF, is a physical object whose operation cannot be reproduced ("cloned") in physical way, 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 a semiconductor device such as a microprocessor. PUFs are often based on unique physical variations occurring naturally during semiconductor manufacturing. A PUF is a physical entity embodied in a physical structure. PUFs are implemented in integrated circuits, including FPGAs, and can be used in applications with high-security requirements, more specifically cryptography, Internet of Things (IOT) devices and privacy protection.
