Abstract
Various embodiments are generally directed to authenticating a chain of components of boot software of a computing device. An apparatus comprises a processor circuit and storage storing an initial boot software component comprising instructions operative on the processor circuit to select a first set of boot software components of multiple sets of boot software components, each set of boot software components defines a pathway that branches from the initial boot software component and that rejoins at a latter boot software component; authenticate a first boot software component of the first set of boot software components; and execute a sequence of instructions of the first boot software component to authenticate a second boot software component of the first set of boot software components to form a chain of authentication through a first pathway defined by the first set of boot software components. Other embodiments are described and claimed herein.
