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