IEEE 802.11i
The WPA2 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.
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 Standard)
procedure. CCM (Counter with CBC-MAC) defines how
the AES procedure is applied to WLAN packets.
FRITZ!Box Fon WLAN 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 Fon WLAN 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. Ra-
dio signals can also be received outside of office or residen-
tial spaces and abused for criminal purposes.
Therefore it is important that no unauthorized users can reg-
ister in a WLAN to use its Internet access or shared network
resources.
FRITZ!Box Fon WLAN includes settings on various levels that
contribute to the security of your WLAN and thus to the secu-
rity of your computers.
