Abstract:

In many embedded systems and the Internet of Things (IoT) applications, resources like CPU, memory, and battery power are so limited that they cannot afford the classic cryptographic security solutions. Meanwhile, the security requirement on these systems/devices is not as high as the traditional secure systems. This creates the challenge and opportunity for the study of lightweight security on resource constrained systems. In this talk, we use authentication as an example to demonstrate how hardware and system physical characteristics can help to build lightweight security primitives. More specifically, after a brief introduction of IoT system's demand of authentication and the circuit fingerprinting techniques for chip identification, we will focus on how to elevate the fabrication variation during chip manufacturing process to high level applications for authentication purposes. We will report our recent work on image processing under voltage over scaling for device authentication, GPS spoofing detection and survival, and machine learning model inversion attack defense. These practical approaches are promising alternatives for the classical crypto-based authentication protocols for the embedded and IoT devices in the smart world.
