ABSTRACT:
A device and method for providing a secure execution environment includes retrieving a boot loader, for example, from the memory of an electronic device or from a peripheral component. Next, a determination is made as to whether the boot loader is authorized to be executed on the corresponding electronic device. If the boot loader is authorized, then the boot loader code is executed. By only allowing execution of authorized boot loaders, security related breaches are substantially reduced or eliminated; thereby, enhancing device integrity.
