Firmware authentication
Firmware authentication in Information Handling Systems (IHSs) are disclosed. In some embodiments, an IHS may include a controller having a memory, the memory configured to store a plurality of firmware volumes, each of the plurality of firmware volumes including a plurality of firmware files. The IHS may also include a Basic Input/Output System (BIOS) operably coupled to the controller, the BIOS having program instructions stored thereon that, upon execution, cause the BIOS to authenticate two or more firmware files within a given one of the plurality of firmware volumes using a single digital signature. In another embodiment, a method may include creating a firmware volume, adding a plurality of firmware files to the firmware volume, and creating a digital signature based upon at least one of the plurality of firmware files, where the digital signature, upon being authenticated, allows a BIOS to load any of the plurality of firmware files.
