rfc.4785 - Pre-Shared Key (PSK) Ciphersuites with NULL Encryption for TLS
02.02.2007
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.
