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 and presents a new registry changes for some entries of the registry.

digital signatures over DNS data to provide source authentication and digital signatures over DNS data to provide source authentication and
integrity protection. DNSSEC uses an IANA registry to list codes for integrity protection. DNSSEC uses an IANA registry to list codes for
digital signature algorithms (consisting of a cryptographic algorithm digital signature algorithms (consisting of a cryptographic algorithm
