SMART: Secure and Minimal Architecture for (Establishing a Dynamic) Root of Trust

Remote attestation is the process of securely verifying internal state of a remote hardware platform. It can be achieved either statically (at boot time) or dynamically, at run-time in order to establish a dynamic root of trust. The latter allows full isolation of a code region from preexisting software (including the operating system) and guarantees untampered execution of this code. Despite the untrusted state of the overall platform, a dynamic root of trust facilitates execution of critical code. Prior software-based techniques lack concrete security guarantees, while hardware-based approaches involve security co-processors that are too costly for low-end embedded devices
