Nové drafty IPSEC - eliptické křivky

Autorem draftů je J. Solinas (NSA).

1)ECC Groups For IKEv2
This document describes ECC groups for use as Diffie-Hellman groups in the Internet Key Exchange version 2 (IKEv2) protocol. These new groups are defined to align IKEv2 with other standards, particularly NIST standards, and with and to provide more efficient implementation than in previously defined groups.

2) ECP Groups For IKE
This document describes new ECC groups for use in the Internet Key Exchange (IKE) protocol in addition to previously defined groups. Specifically, the new curve groups are based on modular arithmetic rather than binary arithmetic. These new groups are defined to align IKE with other ECC implementations and standards, particularly NIST standards. In addition, the curves defined here can provide more efficient implementation than previously defined ECC groups.

3)IKEv2 Authentication Using ECDSA
This document describes how the Elliptic Curve Digital Signature Algorithm (ECDSA) may be used as the authentication method within the Internet Key Exchange protocol, version 2 (IKEv2). ECDSA may provide benefits including computational efficiency, small signature sizes, and minimal bandwidth, compared to other available digital signature methods. This document adds ECDSA capability to IKEv2 without introducing any changes to existing IKEv2 operation.
