For WPA (Wi-Fi Protected Access)
The WPA (WiFi-Protected Access) authentication is suitable for enterprises. It must be used in conjunction
with an authentication server such as RADIUS to provide centralized access control and management. It can
provide stronger encryption and authentication solution than none WPA modes.
Data Encryption:
Select the data encryption method for the WPA mode. There are three types that you can choose,
TKIP, AES, TKIP+AES.
TKIP (Temporary Key Integrity Protocol) takes the original master key only as a starting point and
derives its encryption keys mathematically from this master key. Then it regularly changes and
rotates the encryption keys so that the same encryption key will never be used twice.
AES (Advanced Encryption Standard) provides security between client workstations operating in ad
hoc mode. It uses a mathematical ciphering algorithm that employs variable key sizes of 128, 192
or 256 bits.
TKIP+AES combine the features and functions of TKIP and AES.
WPA Group Rekey Interval:
Enter the time for the WPA group rekey interval. The unit is second. With increasing rekey interval,
user bandwidth requirement is reduced. On the other hand, the longer the rekey interval, the longer
the delay for a new user to gain group access.
RADIUS Server IP Address, RADIUS UDP Port, and RADIUS Shared Secret:
Please refer to the elucidation in the previous 802.1x section.
After finishing the settings, click Apply for activation.
