What are the differences between WPA-CCMP and WPA2-CCMP?

I know CCMP isn't mandatory on WPA capable devices. I know the standard is about WPA2.

But what are the technical differences between these two modes? There are no clear answers anywhere.

WPA/2 is a wifi connection protocol, and is used to gain access to a wireless network - getting through the door.

Once through the door, you then need to talk to people in the room. Your data (email, web traffic, etc) is then encrypted, usually using CCMP or TKIP. Without going into detail, TKIP encrypts each packet using a different key, whereas CCMP is a single key encryption for the duration of you connection.

Personally, I'm not sure of the pros and cons of each - maybe someone more technical can answer that question.

    My question is specifically about WPA-CCMP vs WPA2-CCMP. Not about TKIP. – pHeoz Mar 15 '16 at 11:19
