Wireless LAN—Getting Technical
FRITZ!Box 3272 83
The Standard for Security
IEEE 802.11i
The WPA2 security mechanism is defined in the IEEE 802.11i
standard. WPA2 is an extension of the familiar security mech-
anism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the AES-
CCMP encryption process.
FRITZ!Box supports the AES encryption procedure as part of
the WPA2 mechanism, and the TKIP encryption procedure as
part of the WPA mechanism. This means that the FRITZ!Box
can be used in combination with any wireless devices that al-
so support WPA2 with AES or WPA with TKIP.
11n, 11g, 11b
In your radio network there are only wireless devices that are com-
patible with one or all of the following standards:
• 802.11n
• 802.11g
• 802.11b
Set the following mode in the FRITZ!Box: 802.11n+g+b
Mechanism Encryption
WPA TKIP (Temporary Key Integrity Protocol)
WPA2 TKIP
AES-CCMP
based on the extremely secure AES (Advanced
Encryption Standard) procedure. CCMP
(Counter Mode with CBC-MAC Protocol) de-
fines how the AES procedure is applied to
wireless LAN packets.
