From UEFI spec 2.3.1, Section 27.5 "Firmware/OS Key Exchange: creating trust relationships", there is only a single "Platform Key", which the "platform owner" (= OEM, I guess) uses to sign authorized bootable code. Once an OS is booted, it can add extra "Key Exchange Keys", which it entrusts, to the public key database.
PS : Speaking of EFI, am I the only one annoyed by the way it mandates use of Microsoft's executable formats for loadable binaries ?
