## @file # Runtime DXE part corresponding to SMM authenticated variable module. # # This module installs variable arch protocol and variable write arch protocol to provide # variable service. This module need work together with SMM authenticated variable module. # # Caution: This module requires additional review when modified. # This driver will have external input - variable data. # This external input must be validated carefully to avoid security issues such as # buffer overflow or integer overflow. # The whole SMM authentication variable design relies on the integrity of flash part and SMM. # which is assumed to be protected by platform. All variable code and metadata in flash/SMM Memory # may not be modified without authorization. If platform fails to protect these resources, # the authentication service provided in this driver will be broken, and the behavior is undefined. # # Copyright (c) 2010 - 2019, Intel Corporation.
