EdDSA for DNSSEC
draft-ietf-curdle-dnskey-eddsa-02
Abstract
This document describes how to specify EdDSA keys and signatures in
DNS Security (DNSSEC). It uses the Edwards-curve Digital Security
Algorithm (EdDSA) with the choice of two curves, Ed25519 and Ed448.

1. Introduction
DNSSEC, which is broadly defined in [RFC4033], [RFC4034], and
[RFC4035], uses cryptographic keys and digital signatures to provide
authentication of DNS data. Currently, the most popular signature
algorithm in use is RSA. GOST ([RFC5933]) and NIST-specified
elliptic curve cryptography ([RFC6605]) are also standardized.
[I-D.irtf-cfrg-eddsa] describes the elliptic curve signature system
EdDSA and recommends two curves, Ed25519 and Ed448.
This document defines the use of DNSSEC's DS, DNSKEY, and RRSIG
resource records (RRs) with a new signing algorithm, Edwards-curve
Digital Signature Algorithm (EdDSA) using a choice of two instances:
Ed25519 and Ed448.
2. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].
3. DNSKEY Resource Records
An Ed25519 public key consists of a 32-octet value, which is encoded
into the Public Key field of a DNSKEY resource record as a simple bit
string. The generation of a public key is defined in Section 5.1.5
in [I-D.irtf-cfrg-eddsa].

Internet-Draft EdDSA for DNSSEC November 2016
An Ed448 public key consists of a 57-octet value, which is encoded
into the Public Key field of a DNSKEY resource record as a simple bit
string. The generation of a public key is defined in Section 5.2.5
in [I-D.irtf-cfrg-eddsa].
