**Cipher Block Chaining Message Authentication Code** (**CBC-MAC**) is a technique to construct a message authentication code from a block cipher.

The idea is to create a "chain" of blocks where each block depends on the encryption of the previous block. 

Some examples of protocols that use CBC-MAC:

- CCMP
- GCMP
