Securing pressure measurements using SensorPUFs Conference Paper uri icon


  • © 2016 IEEE. We present a micro-electro-mechanical (MEM) relay based physical unclonable function (PUF) that is capable of sensing pressure while providing an assurance of authenticity. The unique properties of the SensorPUF arise from the pressure sensitivity of electrostatically actuated MEM relay structures. Thus, pres sure sensing is made secure by the integration of the sensor reading with the challenge-response generation circuitry. We evaluate the pressure SensorPUF design in terms of uniqueness, diffuseness, uniformity and bit-aliasing while considering the effect of pressure.
