               AES Encryption with HMAC-SHA2 for Kerberos 5

Abstract

   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.
