+#  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.
