Title : Simplified Updates of DNS Security (DNSSEC) Trust Anchors
Author : Warren Kumari
Filename : draft-wkumari-dnsop-trust-management-00.txt
Pages : 8

Abstract:
This document describes a simple means for automated updating of
DNSSEC trust anchors. This mechanism allows the trust anchor
maintainer to monitor the progress of the migration to the new trust
anchor, and so predict the effect before decommissioning the existing
trust anchor.
It is primarily aimed at the root DNSSEC trust anchor, but should be
applicable to trust anchors elsewhere in the DNS as well.
[ Ed note - informal summary: One of the big issues with rolling the
root key is that it is unclear who all is using RFC5011, who all has
successfully fetched and installed the new key, and, most
importantly, who all will die when the old key is revoked. A
secondary problem is that the response sizes suddenly increase,
potentially blowing the MTU limit. This document describes a method
that is basically CDS, but for the root key (or any other trust
anchor). Unlike the CDS record though, this record lives at a
special name - by querying for this name, the recursive exposes its
list of TAs to the auth server (signalling upstream) . This allows
the TA maintainer to predict how many, and who all will break. It
also allows the pre-publication of a key before using it, and so
avoids the need to double response sizes...]
