WPA2
Also know as IEEE 802.11i, is an amendment to the 802.11 standard specifying

security mechanisms for wireless networks. The 802.11i scheme makes use of the
Advanced Encryption Standard (AES) block cipher; WEP and WPA use the RC4
stream cipher.
The 802.11i architecture contains the following components: 802.1X for

authentication (entailing the use of EAP and an authentication server), RSN for
keeping track of associations, and AES-based CCMP to provide confidentiality,
integrity and origin authentication.
WPA2 implements the full standard, but will not work with some older network

cards. Both provide good security, with two significant issues:
- either WPA or WPA2 must be enabled and chosen in preference to WEP.
WEP is usually presented as the first security choice in most
installation instructions.
- in the "Personal" mode, the most likely choice for homes and small offices,
a passphrase is required that, for full security, must be longer than the
typical 6 to 8 character passwords users are taught to employ.
With the RC4 released to the general public the IEEE implemented the Advanced

Encryption Standard (AES) as the cipher engine for 802.11i, which the Wi-Fi
Alliance has branded as WPA2.
