CCMP is the standard encryption protocol for use with the Wi-Fi Protected Access II (WPA2) standard and is much more secure than the Wired Equivalent Privacy (WEP) protocol and Temporal Key Integrity Protocol (TKIP) of Wi-Fi Protected Access (WPA). CCMP provides the following security services:[2]
Data confidentiality; ensures only authorized parties can access the information
Authentication; provides proof of genuineness of the user
Access control in conjunction with layer management
Because CCMP is a block cipher mode using a 128-bit key, it is secure against attacks to the 264 steps of operation. Generic meet-in-the-middle attacks do exist and can be used to limit the theoretical strength of the key to 2n∕2 (where n is the number of bits in the key) operations needed.[3]
