                   Signature Authentication in IKEv2
              draft-kivinen-ipsecme-signature-auth-06.txt

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 a fixed hash algorithm tied to each group.  This
   document generalizes IKEv2 signature support to allow any signature
   method supported by the PKIX and also adds signature hash algorithm
   negotiation.  This is a generic mechanism, and is not limited to
   ECDSA, but can also be used with other signature algorithms.
