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 WPA mechanism stipulates the TKIP (Temporary
Key Integrity Protocol) for encryption.
Besides TKIP, the WPA2 mechanism also defines the
AES-CCM encryption procedure, which is based on
the extremely secure AES (Advanced Encryption Stan-
dard) procedure. CCM (Counter with CBC-MAC) de-
fines how the AES procedure is applied to WLAN
packets.
The FRITZ!WLAN USB Stick 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 can be used in com-
bination with any WLAN access points that also support
WPA2 with AES or WPA with TKIP.
6.2 Security
Security is of utmost importance within radio networks.
Radio signals can also be received outside of the office or
home 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.
