CBC-MAC

   Also found in: Acronyms, Wikipedia 0.01 sec.
CBC-MAC
(Cipher Block Chaining-Message Authentication Code) A message integrity method that uses block ciphers such as DES and AES. Each block of plaintext is encrypted with the cipher and then XOR'd with the second encrypted block. That result is XOR'd with the third encrypted block and so on in series. See MAC, message integrity, CBC, XOR and AES/CCMP.
