A multi-die device a first die containing a plurality of first die signal path elements configured to propagate a stimulus signal and a second die containing a plurality of second die signal path elements configured to propagate the stimulus signal. The multi-die device further includes an interposer configured to establish signal communication between the first die and the second die so as to deliver the stimulus signal from the plurality of first die signal path elements to the plurality of second die signal path elements to generate a propagation delay. The propagation delay is used to generate a single unified PUF response that is indicative of the authenticity of the multi-die device.

A wideband small-scale cavity oscillator includes a single resonating chamber, a negative resistance diode, at least one capacitive waveguide obstacle, and a tap. The single resonating chamber includes a length, width, and height. The length is greater than the width and height. The negative resistance diode is centrally disposed in the single resonating chamber, and the at least one capacitive waveguide obstacle is disposed in the single resonating chamber. The tap is disposed along the length of the single resonating chamber. A method of manufacturing a wideband small-scale cavity oscillator is provided, which includes providing a single resonating chamber including a length, width, and height, disposing a negative resistance diode centrally in the single resonating chamber, disposing at least one capacitive waveguide obstacle in the single resonating chamber, and disposing a tap along the length of the single resonating chamber.
