The IESG has approved the following document: - 'Authenticated Received Chain (ARC) Protocol' (draft-ietf-dmarc-arc-protocol-23.txt) as Experimental RFC This document is the product of the Domain-based Message Authentication, Reporting & Conformance Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dmarc-arc-protocol/ 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. Personnel: Document Shepherd: Tim Wicinski Area Director: Alexey Melnikov
