Abstract

The secure chain of trust steps to boot-up a computing device are split between the shutdown procedure of the computing device and the boot-up procedure of the computing device to reduce the time required for the computing device to boot-up. The main image associated with a central processing unit of the computing device is validated during the shutdown procedure of the computing device such that the operating system for the central processing unit is available when the computing device receives an action to power on. The boot-up time for the computing device is reduced, which allows the computing device to boot-up within an established time frame.
