Abstract:
Systems and method are provided for determining a reliability of a physically unclonable function (PUF) cell of a device. One or more activation signals are provided to a PUF cell under a plurality of conditions. A PUF cell output provided by the PUF cell under each of the plurality of conditions is determined. A determination is made of a number of times the PUF cell output of the PUF cell is consistent. And a device classification value is determined based on the determined number of times for a plurality of PUF cells.
