This message starts a WG Last Call for:
draft-ietf-lake-edhoc-psk-08

This Working Group Last Call ends on 2026-07-15

Abstract:
   This document specifies a Pre-Shared Key (PSK) authentication method
   for the Ephemeral Diffie-Hellman Over COSE (EDHOC) Lightweight
   Authenticated Key Exchange (LAKE) protocol.  The PSK method provides
   mutual authentication, ephemeral key exchange, identity protection,
   and quantum resistance while incurring lower computational costs than
   the public-key authentication methods specified for EDHOC.  It is
   suited for systems where nodes share a PSK provided out-of-band
   (external PSK) and enables efficient session resumption with less
   computational overhead when the PSK is provided from a previous EDHOC
   session (resumption PSK).  This document details the PSK message
   flow, key derivation changes, message formatting, processing, and
   security considerations.
