For the WPA network Authentication, the settings
that you can adjust including WPA Algorithms,
RADIUS Server Address, RADIUS Port, Shared key,
Key Renewal Timeout.
WPA Algorithms:
Select the data encryption for the
WPA mode. There are two types that you can choose,
TKIP and AES.
RADIUS Server Address:
RADIUS Server is a
protocol for carrying authentication, authorization,
and configuration information between a Network
Access Server which desires to authenticate its links
and a shared Authentication Server. Please type in the
IP Address for the RADIUS Server.
RADIUS Port:
Except for the IP address of the
RADIUS Server, you have to enter the port number
for the server. Port 1812 is the reserved
RADIUS-authentication port described in RFC 2138.
Earlier RADIUS clients use port 1945. The default
value will be shown on this box. You can keep and
use it.
Shared Key:
A Shared Key is like a password,
which is used between IAS and the specific RADIUS
client to verify identity. Both IAS and the RADIUS
client must be use the same Shared for successful
communication to occur. Type in the words for the
Shared Key.
Key Renewal Timeout
: Type in the time for the
WAP group rekey interval. The unit is second.
TKIP takes the original master key only as a
starting point and derives its encryption keys
mathematically from this mater key. Then it
regularly changes and rotates the encryption keys
so that the same encryption key will be never used
twice.
AES 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.
After finished settings, click
Save Settings
for
activation for next time.
