Abstract
A method and an information handling system (IHS) for authenticating unified extensible firmware interface (UEFI) images in an IHS. The method includes receiving, by a processor of the IHS, a request to authenticate an image. The method also includes determining a type of the image and retrieving, from an entry within a UEFI signature database, a certificate utilized to sign the image. The method further includes determining a verification entry of a verification database of the HIS that corresponds to the entry of the UEFI signature database and identifying, from the verification entry, a particular type of image which the certificate may be used to authenticate. The method further includes determining whether the type of the image is the particular type. In response to determining the type of the image is the particular type, the method includes authenticating the image using the certificate.
