Trusted sensors and remote sensing

Abstract

Remote trusted operation is essential for many types of sensors in an even greater number of applications. It is often crucial to secure guarantees that a particular sensor sample is taken by a specific sensor at a particular time and stated location. We present the first generic system architecture and security protocol that provides low cost, low power, and low latency trusted remote sensing. The approach employs already known randomized challenges and public physically unclonable function with a new concept of interleaved operational and security circuitry.
