Abstract
A method includes a unified extensible firmware interface of a compute node identifying an option ROM or an OS boot loader within the compute node, wherein the option ROM or OS boot loader stores a signed image that can be verified using a required digital certificate. The method further includes determining that the unified extensible firmware interface does not store the required digital certificate in a revocation database or in an authorization database. Still further, the method includes automatically identifying the required digital certificate in a database of digital certificates other than the revocation database or the authorization database, and providing the required digital certificate to the authorization database.
