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.

 RFC 4785        PSK NULL Encryption Ciphersuites for TLS    January 2007

 1.  Introduction

   The RFC for Pre-Shared Key (PSK) based Transport Layer Security (TLS)    [TLS-PSK] specifies ciphersuites for supporting TLS using pre-shared    symmetric keys.  However, all the ciphersuites defined in [TLS-PSK]    require encryption.  However there are cases when only authentication    and integrity protection is required, and confidentiality is not    needed.  There are also cases when confidentiality is not permitted -    e.g., for implementations that must meet import restrictions in some    countries.  Even though no encryption i...
