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.
