DNS Security (DNSSEC) DNSKEY Algorithm IANA Registry Updates
draft-ietf-dnsext-dnssec-registry-update-00
Abstract
The DNS Security Extensions (DNSSEC) requires the use of
cryptographic algorithm suites for generating digital signatures over
DNS data. The algorithms specified for use with DNSSEC are reflected
in an IANA maintained registry. This document presents a set of
changes for some entries of the registry and presents a new registry
table.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at http://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months
and may be updated, replaced, or obsoleted by other documents at any
time. It is inappropriate to use Internet-Drafts as reference
material or to cite them other than as "work in progress."

Internet-Draft IANA Registry Update January 2012
1. Introduction
The Domain Name System (DNS) Security Extensions (DNSSEC) [RFC4033],
[RFC4034], [RFC4035], [RFC4509], [RFC5155], and [RFC5702] uses
digital signatures over DNS data to provide source authentication and
integrity protection. DNSSEC uses an IANA registry to list codes for
digital signature algorithms (consisting of a cryptographic algorithm
and one-way hash function).
This document replaces the current IANA registry for Domain Name
System Security (DNSSEC) Algorithm Numbers with a newly defined
registry table. This new table (Section 2.2 below) contains a
collection of changes to selected entries originally set aside for
future algorithm specification that did not occur. These entries are
changed to "Reserved" to avoid potential conflicts with older
implementations. This document also brings the list of references
for entries up to date.
2. The DNS Security Algorithm Number Sub-registry
The DNS Security Algorithm Number sub-registry (part of the Domain
Name System (DNS) Security Number registry) will be replaced with the
table below. There are additional differences to entries that are
described in sub-section 2.1 and the overall new registry table is in
sub-section 2.2.
2.1. Updates and Additions
This document updates three entries in the Domain Name System
Security (DNSSEC) Algorithm Registry. They are:
The description for assignment number 4 is changed to "Reserved".
The description for assignment number 9 is changed to "Reserved".
The description for assignment number 11 is changed to "Reserved".
The above values are changed to "Reserved" because they were
placeholders for algorithms that were not fully specified for use
with DNSSEC. Older implementations may still have these algorithm
codes assigned, so these codes are reserved to prevent potential
incompatibilities.

3. IANA Considerations
This document replaces the Domain Name System (DNS) Security
Algorithm Numbers registry with new registry table is in Section 2.2.
The changes include moving three registry entries to "Reserved" and
updating the reference list for entries.
The original Domain Name System (DNS) Security Algorithm Number
registry is available at
http://www.iana.org/assignments/dns-sec-alg-numbers.

4. Security Considerations
This document replaces the Domain Name System (DNS) Security
Algorithm Numbers registry with an updated table. It is not meant to
be a discussion on algorithm superiority. No new security
considerations are raised in this document.
