AES-CCM Cipher Suites for Transport Layer Security (TLS)

This memo describes the use of the Advanced Encryption Standard (AES) in the Counter with Cipher Block Chaining Message Authentication Code (CBC-MAC) Mode (CCM) of operation within Transport Layer Security (TLS) and Datagram TLS (DTLS) to provide confidentiality and data origin authentication. The AES-CCM algorithm is amenable to compact implementations, making it suitable for constrained environments.
