Abstract
We propose a novel variety of sensor that extends the functionality of conventional physical unclonable functions to provide authentication, unclonability, and verification of a sensed value. This new class of device addresses the vulnerability in typical sensing systems whereby an attacker can spoof measurements by interfering with the analog signals that pass from the sensor element to the embedded microprocessor. The concept can be applied to any type of analog sensor.
