ISC-FLAT: On the Conflict Between Control Flow Attestation and Real-Time Operations. (arXiv:2303.03561v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
The wide adoption of IoT gadgets and Cyber-Physical Systems (CPS) makes
embedded devices increasingly important. While some of these devices perform
mission-critical tasks, they are usually implemented using Micro-Controller
Units (MCUs) that lack security mechanisms on par with those available to
general-purpose computers, making them more susceptible to remote exploits that
could corrupt their software integrity. Motivated by this problem, prior work
has proposed techniques to remotely assess the trustworthiness of embedded MCU
software. Among them, Control Flow Attestation (CFA) …
