Revised IANA Considerations for DNSSEC
draft-hoffman-dnssec-iana-cons-01
Abstract
This document changes the review requirements needed to get some
DNSSEC algorithms and resource records added to IANA registries. It
updates RFC 6014 to include hash algorithms for DS records and NSEC3
parameters.

1. Introduction
DNSSEC is primarily described in [RFC4033], [RFC4034], and [RFC4035].
DNSSEC commonly uses two resource records beyond those defined in RFC
4034: DS [RFC3658] and NSEC3 [RFC5155].
[RFC8126] describes the requirements for listing in the myriad IANA
registries.
[RFC6014] updated the requirements for how DNSSEC cryptographic
algorithm identifiers in the IANA registries are allocated, reducing
the requirements from being "Standards Action" to "RFC Required".
However, the IANA registry requirements for hash algorithms for DS
records and for the hash algorithms used in NSEC3 are still
"Standards Action". This document updates RFC 6014 to bring the
requirements for DS records and NSEC3 hash algorithms in line with
the rest of the DNSSEC cryptographic algorithms.
2. IANA Considerations
In the "Domain Name System Security (DNSSEC) NextSECure3 (NSEC3)
Parameters" registry, the registration procedure for "DNSSEC NSEC3
Flags", "DNSSEC NSEC3 Hash Algorithms", and "DNSSEC NSEC3PARAM Flags"
are changed from "Standards Action" to "RFC Required".
In the "Delegation Signer (DS) Resource Record (RR) Type Digest
Algorithms" registry, the registration procedure for "Digest
Algorithms" is changed from "Standards Action" to "RFC Required".
3. Security Considerations
Changing the requirements for getting security algorithms added to
IANA registries as described in this document will make it easier to
get good algorithms added to the registries, and will make it easier
to get bad algorithms added to the registries. It is impossible to
weigh the security impact of those two changes.

Appendix A. Other Options for Requirements Level
During an early discussion in the DNSOP Working Group, it was
proposed that the requirements for registry allocation for DS
resource records be "Specification Required". This would reduce the
work required of specification authors, and of the RFC Editor, while
still requiring review by an expert reviewer and a long-lived
specification.
