Signature Authentication in IKEv2
draft-kivinen-ipsecme-signature-auth-02.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 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.
