This document defines several new cipher suites for version 1.2 of the Transport Layer Security (TLS) protocol and version 1.2 of the Datagram Transport Layer Security (DTLS) protocol. These cipher suites are based on the Ephemeral Elliptic Curve Diffie-Hellman with Pre-Shared Key (ECDHE_PSK) key exchange together with the Authenticated Encryption with Associated Data (AEAD) algorithms AES-GCM and AES-CCM. PSK provides light and efficient authentication, ECDHE provides forward secrecy, and AES-GCM and AES-CCM provide encryption and integrity protection.

This document specifies two encryption types and two corresponding checksum types for Kerberos 5. The new types use AES in CTS mode (CBC mode with ciphertext stealing) for confidentiality and HMAC with a SHA-2 hash for integrity.

This memo describes SIV (Synthetic Initialization Vector), a block cipher mode of operation. SIV takes a key, a plaintext, and multiple variable-length octet strings that will be authenticated but not encrypted. It produces a ciphertext having the same length as the plaintext and a synthetic initialization vector. Depending on how it is used, SIV achieves either the goal of deterministic authenticated encryption or the goal of nonce-based, misuse-resistant authenticated encryption. This memo provides information for the Internet community.

An authenticated encryption algorithm combines encryption and integrity into a single operation; such algorithms may also be referred to as combined modes of an encryption cipher or as combined mode algorithms. This document describes the use of authenticated encryption algorithms with the Encrypted Payload of the Internet Key Exchange version 2 (IKEv2) protocol.

The use of two specific authenticated encryption algorithms with the IKEv2 Encrypted Payload is also described; these two algorithms are the Advanced Encryption Standard (AES) in Galois/Counter Mode (AES GCM) and AES in Counter with CBC-MAC Mode (AES CCM). Additional documents may describe the use of other authenticated encryption algorithms with the IKEv2 Encrypted Payload. [STANDARDS-TRACK]

A Message Authentication Code (MAC) is a key-dependent one way hash function. One popular way to construct a MAC algorithm is to use a block cipher in conjunction with the Cipher-Block-Chaining (CBC) mode of operation. The classic CBC-MAC algorithm, while secure for messages of a pre-selected fixed length, has been shown to be insecure across messages of varying lengths such as the type found in typical IP datagrams. This memo specifies the use of AES in CBC mode with a set of extensions to overcome this limitation. This new algorithm is named AES-XCBC-MAC-96. [STANDARDS-TRACK]
