Abstract

   This document describes how to include trust into the ASTM Remote ID
   specification defined in ASTM F3411-19 under a Broadcast Remote ID
   (RID) scenario.  It defines a few different message schemes (based on
   the Authentication Message) that can be used to assure past messages
   sent by a UA and also act as an assurance for UA trustworthiness in
   the absence of Internet connectivity at the receiving node.
