+/**
+  The function is used to do the authentication for FMP capsule based upon
+  EFI_FIRMWARE_IMAGE_AUTHENTICATION.
+
+  The FMP capsule image should start with EFI_FIRMWARE_IMAGE_AUTHENTICATION,
+  followed by the payload.
+
+  If the return status is RETURN_SUCCESS, the caller may continue the rest
+  FMP update process.
+  If the return status is NOT RETURN_SUCCESS, the caller should stop the FMP
+  update process and convert the return status to LastAttemptStatus
+  to indicate that FMP update fails.
+  The LastAttemptStatus can be got from ESRT table or via
+  EFI_FIRMWARE_MANAGEMENT_PROTOCOL.GetImageInfo().
+
+  Caution: This function may receive untrusted input.
+
+  @param[in]  Image                   Points to an FMP authentication image, started from EFI_FIRMWARE_IMAGE_AUTHENTICATION.
+  @param[in]  ImageSize               Size of the authentication image in bytes.
+  @param[in]  PublicKeyData           The public key data used to validate the signature.
+  @param[in]  PublicKeyDataLength     The length of the public key data.
+
+  @retval RETURN_SUCCESS            Authentication pass.
+                                    The LastAttemptStatus should be LAST_ATTEMPT_STATUS_SUCCESS.
+  @retval RETURN_SECURITY_VIOLATION Authentication fail.
+                                    The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_AUTH_ERROR.
+  @retval RETURN_INVALID_PARAMETER  The image is in an invalid format.
+                                    The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.
+  @retval RETURN_UNSUPPORTED        No Authentication handler associated with CertType.
+                                    The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.
+  @retval RETURN_UNSUPPORTED        Image or ImageSize is invalid.
+                                    The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INVALID_FORMAT.
+  @retval RETURN_OUT_OF_RESOURCES   No Authentication handler associated with CertType.
+                                    The LastAttemptStatus should be LAST_ATTEMPT_STATUS_ERROR_INSUFFICIENT_RESOURCES.
