level of assurance to enterprises, small businesses and home users that data will remain protected an that
only authorized users may access their networks.
- WPA2
:
WPA2 is the second generation of WPA security; providing enterprise and consumer WiFi users with a high
level of assurance that only authorized users can access their wireless networks. WPA2 is the certified
interoperable version of the full IEEE 820.11i specification. Like WPA, WPA2 supports IEEE 802.11x / EAP
authentication or PSK technology. It also included a new advanced encryption mechanism using the
Counter-Mode / CBC-MAC Protocol (CCMP) called the Advanced Encryption Standard (AES).
4.4.1.3 Cipher Type
If you selected EAP you will need to select the cipher type for TKIP, AES or Auto. (Default:
TKIP
)
Note
: When you select
WPA
,
WPA2
or
WPA2 only
, you must select
TKIP
,
AES
, or
Auto
from the pull-down
menu.

TKIP : Temporal Key Integrity Protocol is an upgrade to the WEP known as WEP 1.1 that fixed unknown
security problems in WEP’s implementation of the RC4 stream cipher. TKIP scrambled the keys using a
hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered
with.
- AES : Advanced Encryption Standard is the U.S. government’s next-generation cryptography algorithm, which
will replace DES and 3DES. AES works at multiple network layers simultaneously and support 128, 192 and
256 bit keys.
- TKIP and AES : If clients support both the TKIP and AES standards, then this would be the strongest cipher
type to use and combine both the TKIP and AES security.
4.4.1.4 PSK
PSK is the pre-shared key mode of WPA which does not require the inclusion of a RADIUS server in your
network. The user needs to enter a pass phrase in this field. The pass phrase is an alpha-numeric password
between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. Make sure you enter
key exactly the same on all other wireless clients.
Leave blank to enable 802.1X Authentication. (
Default:
password)
