Abstract
A UEFI variable storage system includes a UEFI variable services subsystem coupled to UEFI variable sources, a trusted UEFI variable storage subsystem, and an untrusted UEFI variable storage subsystem. If the UEFI variable services subsystem receives a first UEFI variable during a first UEFI initialization process from a first UEFI variable source and determines that the first UEFI initialization process has not reached an untrusted UEFI variable source point, it stores the first UEFI variable in the trusted UEFI variable storage subsystem. If the UEFI variable services subsystem receives a second UEFI variable during the first UEFI initialization process from a second UEFI variable source and determines that the first UEFI initialization process has reached the untrusted UEFI variable source point, it stores the second UEFI variable in the untrusted UEFI variable storage subsystem.
