RFC Type: Proposed Standard.
In general we have had algorithm drafts as informal RFCs instead of
standard track documents, but some of them has been put on standard
track when they are considered as core algorithms. This is true for
the RFC3526 which defined the current MODP Diffie-Hellman groups used
now, and also for AES etc. Because this document will most likely be
defining the very commonly used Diffie-Hellman groups for future, this
document has been put on the Standard Track.
Technical Summary
This document describes the use of Curve25519 and Curve448 for
ephemeral key exchange in the Internet Key Exchange (IKEv2) protocol.
Working Group Summary
The document did not get much comments in the IPsecME working group,
but as this document just mostly reuses what was defined in the
RFC7748 defining those Diffie-Hellman groups this was expected. This
document just defines how those groups are used in the IKE.
Document Quality
No implementations are known, but there have been implementors
indicating that they would like to implement this, and want to get the
IANA allocations for the groups soon.
Personnel
Authors are Yoav Nir and Simon Josefsson. Kathleen Moriarty is the
responsible Area Director. Tero Kivinen is the document shepherd.
Intellectual Property
All authors have confirmed that they are not aware of any undisclosed
IPR associated with this document. There have been no IPR disclosures.
The algorithms defined in this document are based on the RFC7748
which do not have any IPR disclosures submitted to it.
Downward Normative References
There is normative reference to the informational RFC 7748. The RFC
7748 is the actual algorithm description published by the CFRG.
