Abstract
This document describes an algorithm and a protocol to automate
DNSSEC multi-signer [RFC8901] "Multi-Signer DNSSEC Models" setup,
operations and decomissioning. It primarily deals with Model 2 of
the Multi-Signer specification, where each operator has their own
distinct KSK and ZSK sets (or CSK sets). It makes use of [RFC8078]
"Managing DS Records from the Parent via CDS/CDNSKEY" and [RFC7477]
"Child-to-Parent Synchronization in DNS" to accomplish this.

1. Introduction
[RFC8901] describes the necessary steps and API for a multi-signer
DNSSEC configuration. In this document we will combine [RFC8901]
with [RFC8078] and [RFC7477] to define a fully automatable algorithm
for setting up, operating and decomissioning of a multi-signer DNSSEC
configuration.
One of the special cases of multi-signer DNSSEC is actually the
secure change of DNS operator.

1.1. Out-Of-Scope
In order for any multi-signer group to give consistent answers across
all nameservers, the data contents of the zone also have to be
synchronized (in addition to infrastructure records like NS, DNSKEY,
