Abstract: Systems and methods for codependent physical unclonable function (PUF)/random number generator (RNG) generator pairing for physical provenance are described herein. In one example a device includes physical unclonable function (PUF) circuitry configured to produce a PUF output in response to an input and random number generator (RNG) circuitry configured to output one or more random numbers. The PUF circuitry and the RNG circuitry share one or more components such that an alteration of the RNG circuitry alters the PUF circuitry. The device is configured to determine whether the RNG circuitry is an untainted source of random numbers based on an output of the PUF circuitry.

Abstract: A system is provided. The system includes a physical unclonable function (PUF) circuit having an input, an output and an embedded microelectromechanical system (MEMS) device; and an interface, coupled to the PUF circuit, and being configured to be coupled to a mechanical structure; wherein the embedded MEMS device is configured to detect a parameter or characteristic associated with the mechanical structure and to provide an input to the PUF circuit based on the detected parameter, whereby the PUF circuit uses the input from the embedded MEMS device to extend trust to the mechanical structure.

Abstract: A system that includes: a microelectromechanical system (MEMS) device for generating an output signal at an output of the MEMS device, the MEMS device receiving at least one input signal at an input of the MEMS device; a storage medium configured to store a signal injection function and an output generation function; and a processor, in communication with the MEMS device and the storage medium, the processor configured to run the signal injection function to selectively modify the at least one input signal to produce a modified input signal and to provide the modified input signal to the input of the MEMS device, and that is configured to run an output generation function to extract a random component and a unique component from the output signal, wherein the random component and the unique component are generated by the MEMS device based on the modified at least one input signal.
