Abstract Abstract
The DNS Security Extensions (DNSSEC) requires the use of The DNS Security Extensions (DNSSEC) requires the use of
cryptographic algorithm suites for generating digital signatures over cryptographic algorithm suites for generating digital signatures over
DNS data. The algorithms specified for use with DNSSEC are reflected DNS data. The algorithms specified for use with DNSSEC are reflected
in an IANA maintained registry. This document presents a set of in an IANA maintained registry. This document presents a set of
changes for some entries of the registry. changes for some entries of the registry.

1. Introduction 1. Introduction
The Domain Name System (DNS) Security Extensions (DNSSEC, defined by The Domain Name System (DNS) Security Extensions (DNSSEC, defined by
[RFC4033], [RFC4034], [RFC4035], [RFC4509], [RFC5155], and [RFC5702]) [RFC4033], [RFC4034], [RFC4035], [RFC4509], [RFC5155], and [RFC5702])
use digital signatures over DNS data to provide source authentication use digital signatures over DNS data to provide source authentication
and integrity protection. DNSSEC uses an IANA registry to list codes and integrity protection. DNSSEC uses an IANA registry to list codes
for digital signature algorithms (consisting of an asymmetric for digital signature algorithms (consisting of an asymmetric
cryptographic algorithm and a one-way hash function). cryptographic algorithm and a one-way hash function).
