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 famil-
iar security mechanism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the
AES-CCM encryption process.
The FRITZ!WLAN USB Stick N 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!WLAN USB Stick N can be used in
combination with any WLAN access points that also sup-
port WPA2 with AES or WPA with TKIP.

Security
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.
The necessary requirements for this, which contribute to
the security of your WLAN and of your computers, are inte-
grated in the FRITZ!WLAN control software.

AES-CCM
based on the extremely secure AES (Advanced
Encryption Standard) procedure. CCM (Counter
Mode with Cipher Block Chaining Message Au-
thentication Code) defines how the AES proce-
dure is applied to WLAN packets.
