Hi All, A new TLS extension draft for optimizing TLS/DTLS handshake when PSK is used has been proposed. This extension allows the Client Hello & Server Hello messages to negotiate the PSK Identity to be used thereby reducing the handshake latency to 1 RTT.
This may be useful in IoT environments where DTLS 1.2 + PSK is being proposed for many scenarios. Request your comments & suggestions. Thanks!

Name: draft-jay-tls-psk-identity-extension Revision: 00 Title: TLS/DTLS PSK Identity Extension Document date: 2015-09-28 Group: Individual Submission Pages: 10 URL: https://www.ietf.org/internet-drafts/draft-jay-tls-psk-identity-extension-00.txt Status: https://datatracker.ietf.org/doc/draft-jay-tls-psk-identity-extension/ Htmlized: https://tools.ietf.org/html/draft-jay-tls-psk-identity-extension-00 Abstract: Pre-Shared Key (PSK) based Key Exchange Mechanism is primarily used in constrained environments where resource intensive Asymmetric Cryptography cannot be used. In the Internet of Things (IoT) deployments, constrained devices are commonly used for collecting data via sensors for use in home automation, smart energy etc. In this context, DTLS is being considered as the primary protocol for communication security at the application layer and in some cases, it is also being considered for network access authentication. This document provides a specification for a new extension for Optimizing DTLS and TLS Handshake when the Pre-Shared Key (PSK) based Key Exchange is used. This extension is aimed at reducing the number of messages exchanged and the RTT of the TLS & DTLS Handshakes. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
