                   Signature Authentication in IKEv2

Abstract

   The Internet Key Exchange Version 2 (IKEv2) protocol has limited
   support for the Elliptic Curve Digital Signature Algorithm (ECDSA).
   The current version only includes support for three Elliptic Curve
   groups, and there is fixed hash algorithm tied to each curve.  This
   document generalizes the IKEv2 signature support so it can support
   any signature method supported by the PKIX and also adds signature
   hash algorithm negotiation.  This is generic mechanism, and is not
   limited to ECDSA, but can also be used with other signature
   algorithms.
