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:
