WPA2 – Like WPA, WPA2 supports IEEE 802.1x/EAP authentication or PSK technology.
It also includes a new advanced encryption mechanism using the Advanced Encryption
Standard (AES). AES is required to the corporate user or government users. The
different between WPA and WPA2 is that WPA2 provides data encryption via the AES. In
contrast, WPA uses Temporal Key Integrity Protocol (TKIP).
WPA2-PSK – WPA2-PSK is also for home and small business. The difference between
WPA-PSK and WPA2-PSK is that WPA2-PSK provides data encryption via the AES. In
contrast, WPA-PSK uses Temporal Key Integrity Protocol (TKIP).
WPA 802.1X – 802.1x authentication is required in WPA. In the 802.11 standard, 802.1x
authentication was optional.
WPA2 802.1X – WPA2 is the next-generation Wi-Fi security standard, combining the
most powerful authentication and encryption techniques to protect wireless networks
from unauthorized use. Based upon the recently ratified IEEE 802.11i standard, WPA2
adds the Advanced Encryption Standard (AES) to the original WPA specification to
provide the greatest levels of network security available. The National Institute of
Standards and Technology (NIST) advocate the use of AES security to protect sensitive
digital information on government networks.
802.1x Setting: When you have set the Authentication Type to Open, Shared, WPA or WPA2,
you can also enable IEEE 802.1x setting to use the authentication server or certification server
to authenticate client users.
Encryption Mode:
None – Disable the Encryption mode.
WEP – Enabled the WEP Data Encryption. When the item is selected, you have to
continue setting the WEP Key Length & the key Index.
TKIP – TKIP (Temporal Key Integrity Protocol) changes the temporal key every 10000
packets (a packet is a kind of message transmitted over a network). This insures much
greater security than the standard WEP security.
AES – AES has been developed to ensure the highest degree of security and authenticity
for digital information and it is the most advanced solution defined by IEEE 802.11i for the
security in the wireless network.
Note: All devices in the network should use the same encryption method to ensure the
communication.
WPA Pre-Shared Key: The WPA-PSK key can be from 8 to 64 characters and can be letters
or numbers. This same key must be used on all of the wireless stations in the network.
WEP Key (Key1~Key4): Only valid when using WEP encryption algorithm. The WEP keys are
used to encrypt data transmitted in the wireless network. There are two types of key length:
64-bit & 128-bit. Select the default encryption key form key1 to key4 by selected the radio
button.
