Modo de
operación de un cifrador que garantiza confidencialidad y autenticidad.
(CCM) (N) A block
cipher mode [SP38C] that provides both data confidentiality and data origin
authentication, by combining the techniques of CTR and a CBC-based message
authentication code. (See: block cipher.) [RFC4949:2007]
Counter with
Cipher Block Chaining-Message Authentication Code can provide assurance of the
confidentiality and authenticity of data. CCM is based on an approved symmetric
key block cipher algorithm whose block size is 128 bits, such as the Advanced
Encryption Standard (AES) algorithm currently specified in Federal Information
Processing Standard (FIPS) Pub. 197; thus, CCM cannot be used with the Triple
Data Encryption Algorithm, whose block size is 64 bits. CCM can be considered a
mode of operation of the block cipher algorithm.
