Technical Summary
This document describes how the Elliptic Curve Digital Signature
Algorithm (ECDSA) may be used as the authentication method within the
Internet Key Exchange (IKE) and Internet Key Exchange version 2
(IKEv2) protocols. 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 IKE without introducing any changes to existing IKE
operation.
Working Group Summary
This document is an individual submission. It was discussed in the
IPsec Working Group, but that working group was closed before reaching
consensus on this document. Thus, it is not affiliated with any IETF
Working Group.
Protocol Quality
This document was reviewed by Russ Housley for the IESG.
