SimHAT: Simulated Hardware-based Attestation evaluation Tool

Embedded devices have come to play an important role in our daily lives. Increasingly, diverse fields like healthcare systems, banks and more are using these devices to automate underlying complex tasks. This reliance has led to a significant development – exposure of devices to malicious attacks, including control and subversion of software onboard. Software attestation has been herald as a solution to minimize the effects of malicious attacks on the devices. With low power, relatively small memory size and less processor frequency, standard software attestation techniques cannot be directly applied to embedded devices. To solve this problem, we propose a novel design of simulated hardware-based tool. Our tool can be used to evaluate competing attestation techniques. Furthermore, We present a reference implementation and evaluate the runtime cost of a home-grown attestation procedure.
