CCMP (CBC-MAC) vs TKIP (MIC)

Hi! I was reading about TKIP and CCMP...

 

TKIP seems to have something called MIC, which is a method used to provide integrity to the messages 

 

CCMP seems to have CBC-MAC to do the same, but the CCNA book says this:

Cipher Block Chaining Message Authentication Code (CBC-MAC) used as a message
integrity check (MIC)

 

I have also read that CBC-MAC generates a 64-bit MIC ... Here is where I got confused because I thought MIC was only something related to TKIP... I thought it was a protocol but it seems to mean a message..

 

I would appreciate your help!
