CCMP stands for Counter Mode CBC-MAC Protocol .CCMP, also known asAES CCMP, is the encryption mechanism that has replacedTKIP, and it is the security standard used with WPA2 wireless networks. According to the specifications, WPA2 networks must use CCMP by default (WPA2-CCMP), although CCMP can also be used on WPA networks for improved security (WPA-CCMP).
