  Security2 Architectural Protocol as defined in PI Specification1.2.1 VOLUME 2 DXE\r
\r
  Abstracts security-specific functions from the DXE Foundation of UEFI Image Verification,\r
  Trusted Computing Group (TCG) measured boot, and User Identity policy for image loading and\r
  consoles. This protocol must be produced by a boot service or runtime DXE driver.\r
\r
  This protocol is optional and must be published prior to the EFI_SECURITY_ARCH_PROTOCOL.\r
  As a result, the same driver must publish both of these interfaces.\r
\r
  When both Security and Security2 Architectural Protocols are published, LoadImage must use\r
  them in accordance with the following rules:\r
    The Security2 protocol must be used on every image being loaded.\r
    The Security protocol must be used after the Securiy2 protocol and only on images that\r
    have been read using Firmware Volume protocol.\r
\r
  When only Security architectural protocol is published, LoadImage must use it on every image\r
  being loaded.\r

/**\r
  The DXE Foundation uses this service to measure and/or verify a UEFI image.\r
\r
  This service abstracts the invocation of Trusted Computing Group (TCG) measured boot, UEFI\r
  Secure boot, and UEFI User Identity infrastructure. For the former two, the DXE Foundation\r
  invokes the FileAuthentication() with a DevicePath and corresponding image in\r
  FileBuffer memory. The TCG measurement code will record the FileBuffer contents into the\r
  appropriate PCR. The image verification logic will confirm the integrity and provenance of the\r
  image in FileBuffer of length FileSize . The origin of the image will be DevicePath in\r
  these cases.\r
  If the FileBuffer is NULL, the interface will determine if the DevicePath can be connected\r
  in order to support the User Identification policy.\r
\r
  @param  This             The EFI_SECURITY2_ARCH_PROTOCOL instance.\r
  @param  File             A pointer to the device path of the file that is\r
                           being dispatched. This will optionally be used for logging.\r
  @param  FileBuffer       A pointer to the buffer with the UEFI file image.\r
  @param  FileSize         The size of the file.\r
  @param  BootPolicy       A boot policy that was used to call LoadImage() UEFI service. If\r
                           FileAuthentication() is invoked not from the LoadImage(),\r
                           BootPolicy must be set to FALSE.\r
