Elliptic Curve Cryptography Brainpool Curves for Transport Layer Security Version 1.3
RFC 8734, “Elliptic Curve Cryptography Brainpool Curves for Transport Layer Security Version 1.3”, is an Informational document published in February 2020 by L. Bruckert, J. Merkle, M. Lochter. The canonical text is published by the RFC Editor.
Abstract
Elliptic Curve Cryptography (ECC) Brainpool curves were an option for authentication and key exchange in the Transport Layer Security (TLS) protocol version 1.2 but were deprecated by the IETF for use with TLS version 1.3 because they had little usage. However, these curves have not been shown to have significant cryptographical weaknesses, and there is some interest in using several of these curves in TLS 1.3.
This document provides the necessary protocol mechanisms for using ECC Brainpool curves in TLS 1.3. This approach is not endorsed by the IETF.
