D. McGrew: AUTHOR [+4]
This document describes the use of Advanced Encryption Standard (AES) [AES] in Counter with CBC-MAC Mode (CCM) [CCM] in several TLS cipher suites. AES-CCM provides both authentication and confidentiality (encryption and decryption) and uses as its only primitive the AES encrypt block cipher operation. This makes it amenable to compact implementations, which are advantageous in constrained environments. Of course, adoption outside of constrained environments is necessary to enable interoperability, such as that between web clients and embedded servers, or between embedded clients and web servers. The use of AES-CCM has been specified for the IPsec Encapsulating Security Payload (ESP) [RFC4309] and 802.15.4 wireless networks [IEEE802154].

AES-CCM Elliptic Curve Cryptography (ECC) Cipher Suites for TLS
This memo describes the use of the Advanced Encryption Standard (AES) in the Counter and CBC-MAC Mode (CCM) of operation within Transport Layer Security (TLS) to provide confidentiality and data-origin authentication. The AES-CCM algorithm is amenable to compact implementations, making it suitable for constrained environments, while at the same time providing a high level of security. The cipher suites defined in this document use Elliptic Curve Cryptography (ECC) and are advantageous in networks with limited bandwidth.
