Technical Summary:
The Authenticated Received Chain (ARC) protocol provides an
authenticated "chain of custody" for a message, allowing each entity
that handles a message to see what entities have handled it before,
and to see what the message's authentication assessment was at each step
in the handling. This allows to convey original authentication
assessments across trust boundaries.
Working Group Summary:
The working group process was quite involved, and because this document
is Experimental, there was active discussions on implementations and
experiments that are detailed in the document.
Document Quality:
The document lists the existing implementations of the protocol, and
appears to cover a broad spectrum of both purchased software as well as
open source.
