Abstract
A method includes storing a golden copy of a device tree binary of a system in a trusted execution environment, identifying whether one or more parameters of a running copy of a device tree binary of the system are different from corresponding parameters of the golden copy by comparing the running copy with the golden copy, and performing a corrective action responsive to an indication that at least one of the one or more parameters of the running copy are different from the corresponding parameters of the golden copy.
