ECDHE_PSK Cipher Suites for Transport Layer Security
Overview
RFC 5489, “ECDHE_PSK Cipher Suites for Transport Layer Security”, is an Informational document published in March 2009 by M. Badra, I. Hajjeh. The canonical text is published by the RFC Editor.
Abstract
This document extends RFC 4279, RFC 4492, and RFC 4785 and specifies a set of cipher suites that use a pre-shared key (PSK) to authenticate an Elliptic Curve Diffie-Hellman exchange with Ephemeral keys (ECDHE). These cipher suites provide Perfect Forward Secrecy (PFS). This memo provides information for the Internet community.
