DRIP Authentication Formats
draft-ietf-drip-auth-00
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.
