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-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.
Mechanism Encryption
WPA TKIP (Temporary Key Integrity Protocol)
WPA2 TKIP
AES-CCMP
AES-CCM
based on the extremely secure AES (Ad-
vanced Encryption Standard) procedure.
CCM (Counter with CBC-MAC Protocol) de-
fines how the AES procedure is applied to
WLAN packets.
