     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
