PUF

Abbreviation(s): Physically Unclonable Function

PUFs depend on the uniqueness of their physical microstructure. This microstructure depends on random physical factors introduced during manufacturing. These factors are unpredictable and uncontrollable, which makes it virtually impossible to duplicate or clone the structure. Unclonability means that each PUF device has a unique and unpredictable way of mapping challenges to responses.
