6.9 Configuring WPA2-CCMP (802.11i)

WPA2 is a newer 802.11i standard that provides even stronger wireless security than Wi-Fi Protected
Access (WPA) and WEP. CCMP is the security standard used by the Advanced Encryption Standard
(AES). AES serves the same function TKIP does for WPA-TKIP. CCMP computes a Message Integrity
Check (MIC) using the proven Cipher Block Chaining (CBC) technique. Changing just one bit in a
message produces a totally different result.
WPA2/CCMP is based on the concept of a Robust Security Network (RSN), which defines a hierarchy
of keys with a limited lifetime (similar to TKIP). Like TKIP, the keys the administrator provides are used
to derive other keys. Messages are encrypted using a 128-bit secret key and a 128-bit block of data.
The end result is an encryption scheme as secure as any the access point provides.
