Abstract

A method for securely updating a firmware (FW) of a component of an information handling system (IHS) includes: receiving an update package for the component; analyzing the update package to extract at least a manifest and an FW update file associated with the component; making a first determination that the manifest is authenticated; making, based on the first determination, a second determination that a key revocation criterion is met, in which the key revocation criterion specifies that a certificate revocation list (CRL) does not specify an authentication key to be used to authenticate an updated FW of the component; updating, based on the second determination, the FW of the component using the FW update file, in which, after being updated, the component has the updated FW; and initiating notification of a user of the IHS about the updated FW of the component.
