Pre-Shared Key Ciphersuites with NULL Encryption for Transport Layer Security

Overview

RFC 4785, “Pre-Shared Key Ciphersuites with NULL Encryption for Transport Layer Security”, is a Proposed Standard document published in January 2007 by U. Blumenthal, P. Goel. It has since been updated by RFC 8996. The canonical text is published by the RFC Editor.

Abstract

This document specifies authentication-only ciphersuites (with no encryption) for the Pre-Shared Key (PSK) based Transport Layer Security (TLS) protocol. These ciphersuites are useful when authentication and integrity protection is desired, but confidentiality is not needed or not permitted. [STANDARDS-TRACK]
