D.3 WPA2 (CCMP) Security

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 (Counter Mode with Cipher Block Chaining Message
Authentication Code Protocol) is the preferred encryption protocol in the 802.11i standard. CCMP computes
a

Message Integrity Check

(MIC) using the proven

Cipher Block Message Authentication Code

(CBC-MAC)

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. For detailed steps on
configuring WPA2 for the CB3000 Client Bridge, see

Configuring WPA2 (CCMP) Security Settings on page 3-
