Abstract Abstract
The DNSSEC protocol makes use of various cryptographic algorithms in The DNSSEC protocol makes use of various cryptographic algorithms in
order to provide authentication of DNS data and proof of non- order to provide authentication of DNS data and proof of non-
existence. To ensure interoperability between DNS resolvers and DNS existence. To ensure interoperability between DNS resolvers and DNS
authoritative servers, it is necessary to specify a set of algorithm authoritative servers, it is necessary to specify a set of algorithm
implementation requirements and usage guidelines to ensure that there implementation requirements and usage guidelines to ensure that there
is at least one algorithm that all implementations support. This is at least one algorithm that all implementations support. This
document defines the current algorithm implementation requirements document defines the current algorithm implementation requirements
