Abstract
A method is provided in one example embodiment and includes storing secure boot variables in a baseboard management controller; and sending the secure boot variables to a basic input/output system (BIOS) during a power on self-test, where the BIOS utilizes the secure boot variables during runtime to authenticate drivers and an operating system loader execution. In particular embodiments, the secure boot variables may be included in a white list, a black list, or a key list and, further, stored in erasable programmable read only memory.

A method, comprising:
- storing secure boot variables in a baseboard management controller;
- and
- sending the secure boot variables to a basic input/output system (BIOS).
One or more non-transitory media that includes instructions for execution and when executed by a processor is operable to perform operations, comprising:
- storing secure boot variables in a baseboard management controller;
- and
- sending the secure boot variables to a basic input/output system (BIOS).
A network element, comprising:
- a memory element for storing instructions;
- and
- a processor coupled to the memory element and operable to execute instructions such that the network element is configured to:
- store secure boot variables in a baseboard management controller;
- and
- send the secure boot variables to a basic input/output system (BIOS).
