Transmit if medium is idle otherwise go to 2; Wait for random amount of time and repeat (1) if medium is busy (b) 1 … To make CMAC work for messages that do not consist of a whole number of blocks, CMAC (carefully) derives a second secret value. It comprises of a series of linked operations, some of which involve replacing inputs by specific outputs (substitutions) and others involve shuffling bits around (permutations). CMAC first pads the message so that it contains a whole number of blocks, then the second secret is xored with the final (padded) block before the block cipher is applied.
