==== Counter with cipher block chaining message authentication code (CCM) ====
{{main|CCM mode}}
''Counter with cipher block chaining message authentication code'' (counter with CBC-MAC; CCM) is an [[authenticated encryption]] algorithm designed to provide both authentication and confidentiality.  CCM mode is only defined for block ciphers with a block length of 128 bits.<ref name="NIST SP800-38C">{{cite tech report
