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]. Sury & Edmonds Expires May 19, 2017 [Page 2] 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]. 4. RRSIG Resource RecordsShow full document text
