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 will be 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.
