Protecting actuators in safety-critical IoT systems from control spoofing attacks
Proceedings of the 2nd International ACM Workshop on Security and Privacy …, 2019•dl.acm.org
In this paper, we propose a framework called Contego-TEE to secure Internet-of-Things (IoT)
edge devices with timing requirements from control spoofing attacks where an adversary
sends malicious control signals to the actuators. We use a trusted computing base available
in commodity processors (such as ARM TrustZone) and propose an invariant checking
mechanism to ensure the security and safety of the physical system. A working prototype of
Contego-TEE was developed using embedded Linux kernel. We demonstrate the feasibility …
