Abstract
A pre-boot initialization technique for a computing system allows for encrypting both a manufacturer and original equipment manufacturer firmware routines, as well as handing off data between the manufacturer and original equipment manufacturer firmware routines encrypted with a key provisioned in field programmable fuses with an original equipment manufacturer key. By encrypting the firmware routines and handoff data, security of the pre-boot initialization process is enhanced. Original equipment manufacturer updatable product data may also be encrypted with the original equipment manufacturer key. Additional security may be provided by using trusted input/output capabilities of a trusted execution environment to display information to and receive information from a user. Furthermore, multiple secure phases of configuration may be achieved using wireless credentials exchange components.
