The IESG has received a request from the CURves, Deprecating and a Little more Encryption WG (curdle) to consider the following document: - 'Use of the Elliptic Curve Diffie-Hellman Key Agreement Algorithm with X25519 and X448 in the Cryptographic Message Syntax (CMS)' <draft-ietf-curdle-cms-ecdh-new-curves-07.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-05-28. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes the conventions for using Elliptic Curve Diffie-Hellman (ECDH) key agreement algorithm using curve25519 and curve448 in the Cryptographic Message Syntax (CMS). The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-curdle-cms-ecdh-new-curves/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-curdle-cms-ecdh-new-curves/ballot/ No IPR declarations have been submitted directly on this I-D.
