Configuring WLAN 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 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 provided keys 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 for
associated clients.
