Pre-Shared Key Cipher Suites for TLS with SHA-256/384 and AES Galois Counter Mode

Pre-Shared Key Cipher Suites for TLS with SHA-256/384 and AES Galois Counter Mode CNRS/LIMOS Laboratory RFC 4279 and RFC 4785 describe pre-shared key cipher suites for Transport Layer Security (TLS). However, all those cipher suites use SHA-1 in their Message Authentication Code (MAC) algorithm. This document describes a set of pre-shared key cipher suites for TLS that uses stronger digest algorithms (i.e., SHA-256 or SHA-384) and another set that uses the Advanced Encryption Standard (AES) in Galois Counter Mode (GCM).
