The Standard for Security
The Standard for Security
IEEE 802.11i
The WPA security mechanism is defined in the IEEE 802.11i
standard. WPA2 is an extension of the familiar security
mechanism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the
AES-CCM 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 WLAN adapters that al-
so support WPA2 with AES or WPA with TKIP.

Security
Security is of utmost importance within radio networks. Ra-
dio signals can also be received outside of office or resi-
dential 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.
