Abstract

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.

       Edwards-Curve Digital Security Algorithm (EdDSA) for DNSSEC

Abstract

   This document describes how to specify Edwards-curve Digital Security    Algorithm (EdDSA) keys and signatures in DNS Security (DNSSEC).  It    uses EdDSA with the choice of two curves: Ed25519 and Ed448.
