    abstract =  {This document describes how to include trust into the ASTM Remote ID specification defined in ASTM3411 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.},
