Abstract

Systems and methods for an active transistor PUF circuit with MEMS uniqueness are described herein. In one example, a PUF circuit includes one or more MEMS structures configured to provide an output, wherein the output includes active oscillations, charge, resistance, inductance, and/or capacitance values. The PUF circuit further includes active transistor PUF circuitry communicatively coupled to the one or more MEMS structures. The active transistor PUF circuitry is configured to receive a challenge input and generate a PUF response in response to the challenge input. The PUF response is generated based on the output provided by the one or more MEMS structures and manufacturing variation in components of the active transistor PUF circuitry. The PUF response generated by the active transistor PUF circuitry is an output of the PUF circuit.
