IEEE 802.11n
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 familiar security mech-
anism WPA (Wi-Fi Protected Access).
The main feature of the extension of WPA to WPA2 is the AES-
CCMP encryption process.
The FRITZ!WLAN USB Stick supports the AES encryption pro-
cedure as part of the WPA2 mechanism, and the TKIP encryp-
tion procedure as part of the WPA mechanism. This means
that the FRITZ!WLAN USB Stick can be used in combination
with any WLAN access points that also support WPA2 with
AES or WPA with TKIP.
The use of the 802.11n standard—and thus the availability of
higher throughput rates—is possible only if the WLAN connec-
tion is secured using the WPA2 security mechanism (AES-CCMP).
Mechanism Encryption
WPA TKIP (Temporary Key Integrity Protocol)
WPA2 TKIP
AES-CCMP
based on the extremely secure AES (Ad-
vanced Encryption Standard) procedure.
CCMP (Counter Mode with CBC-MAC Proto-
col) defines how the AES procedure is ap-
plied to WLAN packets.
