Technical Summary
This document describes the use of the Edwards-curve digital
signature algorithm in the IKEv2 protocol as proposed standard. 

Working Group Summary
 Version -01 went through WGLC. Changes suggested by the WG 
   participants were mostly editorial. There were three substantive
   decisions:
    (1) That the new value in the hash function registry requested from
      IANA for "Identity" shall not be zero.
    (2) That we will not use the pre-hashed version of the EdDSA
      function (same decision made by TLS and Curdle working groups)
    (3) That we will use a null context (or context-free Ed25519) for
      IKE (same decision reached in TLS and Curdle working groups)
   The resulting document represents WG consensus.
   The document was reviewed by several regular WG participants.
   Apple reports a working implementation.
