Abstract
The present disclosure presents various systems and methods for implementing a physical unclonable function device. One such method comprises providing an integrated circuit having a plurality of set/reset flip flop logic circuits, wherein each of the set/reset flip flop logic circuits enters a metastable state for a particular input sequence. The method includes varying circuit parameters for each of the plurality of set/reset flip flop logic circuits to account for manufacturing variations in the set/reset flip flop logic circuits and enable generating a stable but random output in response to the particular input sequence. Thus, by applying the particular input sequence to the integrated circuit, a unique identifier for the integrated circuit can be derived from an output response of the plurality of set/reset flip flop logic circuits.
