The IESG has received a request from the Transport Layer Security WG (tls) to consider the following document: - 'Elliptic Curve Cryptography (ECC) Cipher Suites for Transport Layer Security (TLS) Versions 1.2 and Earlier' <draft-ietf-tls-rfc4492bis-12.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 2017-03-03. 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 key exchange algorithms based on Elliptic Curve Cryptography (ECC) for the Transport Layer Security (TLS) protocol. In particular, it specifies the use of Ephemeral Elliptic Curve Diffie-Hellman (ECDHE) key agreement in a TLS handshake and the use of Elliptic Curve Digital Signature Algorithm (ECDSA) and Edwards Digital Signature Algorithm (EdDSA) as authentication mechanisms. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-tls-rfc4492bis/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-tls-rfc4492bis/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: rfc8032: Edwards-Curve Digital Signature Algorithm (EdDSA) (Informational - IRTF Stream) rfc7748: Elliptic Curves for Security (Informational - IRTF Stream) These are already be listed in the acceptable Downref Registry.
