AES-CCM is used in many wireless networking standards. The Algotronix AES-CCM Core implements the Counter with CBC MAC mode of operation of the AES algorithm. This mode of operation is described in NIST Special Publication SP800-38C.
Unlike simple modes of the cipher which provide only confidentiality, CCM provides both confidentiality and authentication. Authentication is the ability to detect tampering with the encrypted message as it passes between the sender and receiver and in most applications, particularly wireless applications, is essential for security. CCM mode also provides a standard method for processing data streams whose length is not a multiple of the 128 bit AES block size.
