The Standard for Security
The WPA2 security mechanism is defined in the
IEEE 802.11i standard. WPA2 is an extension of the famil-
iar security mechanism 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 proce-
dure as part of the WPA mechanism. This means that the
FRITZ!Box can be used in combination with any WLAN
adapters that also support WPA2 with AES or WPA with
TKIP.
Security is of utmost importance within radio networks.
Radio signals can also be received outside of office or res-
idential spaces and abused for criminal purposes.
Therefore it is important that no unauthorized users can
register in a WLAN to use its Internet access or shared net-
work resources.
FRITZ!Box includes settings on various levels that contrib-
ute to the security of your WLAN and thus to the security of
your computers.

CCM (Counter with CBC-MAC) defines how
the AES procedure is applied to WLAN
packets.
