An Information Model for Behavioural Description of Firmware Update and
                           Related Operations
                draft-moran-suit-behavioural-manifest-01

Abstract

   This specification describes an approach to formally defining the
   behaviour of a system under firmware update and secure boot
   conditions.  The behavioural documents described here can be used
   with [Information] to construct a firmware update manifest.
