Observations on Deploying New DNSSEC Cryptographic Algorithms
draft-york-dnsop-deploying-dnssec-crypto-algs-05
Abstract
As new cryptographic algorithms are developed for use in DNSSEC
signing and validation, this document captures the steps needed for
new algorithms to be deployed and enter general usage. The intent is
to ensure a common understanding of the typical deployment process
and potentially identify opportunities for improvement of operations.

1. Introduction
The DNS Security Extensions (DNSSEC), broadly defined in [RFC4033],
[RFC4034] and [RFC4035], make use of cryptographic algorithms in both
the signing of DNS records and the validation of DNSSEC signatures by
recursive resolvers.
The current list of cryptographic algorithms can be found in the IANA
"Domain Name System Security (DNSSEC) Algorithm Numbers" registry
located at <http://www.iana.org/assignments/dns-sec-alg-numbers/>
Algorithms are added to this IANA registry through a process defined
