Abstract
In one embodiment, an apparatus includes: a device having a physically unclonable function (PUF) circuit including a plurality of PUF cells to generate a PUF sample responsive to at least one control signal; a controller coupled to the device, the controller to send the at least one control signal to the PUF circuit and to receive a plurality of PUF samples from the PUF circuit; a buffer having a plurality of entries each to store at least one of the plurality of PUF samples; and a filter to filter the plurality of PUF samples to output a filtered value, wherein the controller is to generate a unique identifier for the device based at least in part on the filtered value. Other embodiments are described and claimed.
