Abstract
This application discloses a physical unclonable function device including physical unclonable function units, each capable of generating an output. The physical unclonable function device can extract bits from the outputs at various inspection locations and utilize the extracted bits to generate an identifier for the physical unclonable function device. An inspection configuration tool can identify the inspection locations and configure the physical unclonable function device with the inspection locations. The inspection configuration tool can sample the physical unclonable function circuitry to identify a plurality of multi-bit outputs, select bit locations in the multi-bit outputs as inspection locations based on bit value stability for the bit locations, and configure the identifier generation circuitry in physical unclonable function device with the inspection locations.
