 #  This driver will have external input - variable data and communicate buffer in SMM mode.\r
 #  This external input must be validated carefully to avoid security issues such as \r
 #  buffer overflow or integer overflow.\r
+#    The whole SMM authentication variable design relies on the integrity of flash part and SMM.\r
+#  which is assumed to be protected by platform.  All variable code and metadata in flash/SMM Memory\r
+#  may not be modified without authorization. If platform fails to protect these resources, \r
+#  the authentication service provided in this driver will be broken, and the behavior is undefined.\r
