(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. |

The newly introduced IP core, JetCombo-3, features Advanced Encryption Standard (AES), Counter mode with CBC-MAC (AES-CCM), Galois-Counter Mode (AES-GCM), and XTS-AES mode (XEX-based Tweaked-codebook-mode with ciphertext-Stealing) all combined in the same IP core by sharing hardware resources. The product line features Advanced Encryption Standard (AES), Counter mode with CBC-MAC (AES-CCM), Galois Counter Mode (AES-GCM), XEX-AES, Triple-DES, Secure Hashing cores, and multiple-standard combined cores. The dsPIC30F Symmetric Key Encryption/Decryption Library functions support multiple modes of operation, including Electronic Code Book (ECB) mode, Cipher Block Chaining mode (CBC), CBC-based Message Authentication (CBC-MAC) mode, Counter (CTR) mode, and combined CBC-MAC and Counter Mode (CCM). |
