Radius Server
A RADIUS server is used to authenticate the connection for clients and return authentication key
parameters to the users to connect to the wireless network.
RADIUS (Remote Authentication Dial-In User Service) utilises a RADIUS server for authentication
and the use of dynamic TKIP, AES, or WEP.
Re-authentication Time: Enter a time in seconds that uses will have to re-authenticate with the
RADIUS server.
Click the “Add” button to add the Radius Server IP Address, Server UDP port and Shared Secret.
The shared secret is used to allow communication between the AP and the RADIUS Server.
12
III. Wired Equivalent Privacy (WEP)
WEP encryption implementation was not put in place with the 802.11 standard. This means that there
are about as many methods of WEP encryption as there are providers of wireless networking
products. In addition, WEP is not completely secure. One piece of information still not encrypted is
the MAC address, which hackers can use to break into a network by spoofing (or faking) the MAC
address.
When selecting WEP encryption, click the “Use WEP Security” to enable the WEP security function.
u 64-bits: selecting the 64bit, you must type 10 values in the following range (0~F, hexadecimal).
u 128-bits: selecting the 128bit, you must type 26 values in the following range (0~F, hexadecimal).
IV. 802.1x Security
To address the shortcomings of WEP for authentication, the industry is working towards solutions
based on the 802.1x specification, which is based on the Extensible Authentication Protocol (EAP).
EAP was designed with flexibility in mind, and it has been used as the basis for a number of network
authentication extensions.
Click to enable the 802.1x security function.
Key Size: select either 64bit or 128-bit for the key size of the 802.1x security.
u Group Key Setting:
No Rekeying: the clients will not need to re-key the password to authenticate with the Radius
Server.
Rekeying Time: Type in the time in minutes when clients will need to re-key the password for
authentication and security.
Rekeying packets: Type in the amount of packets that will be transmitted before clients will need
to re-key the password for authentication and security.
V. Wi-Fi Protected Access (WPA)
Wi-Fi Protected Access (WPA) is the newest and most reliable standard in Wi-Fi security. Two
modes are available: Pre-Shared Key and RADIUS. Pre-Shared Key gives you a choice of two
encryption methods: TKIP (Temporal Key Integrity Protocol), which utilises a stronger encryption
method and incorporates Message Integrity Code (MIC) to provide protection against hackers, and
AES (Advanced Encryption System), which utilises a symmetric 128-Bit block data encryption.
Ø Disable WPA Security: to disable the WPA security.
u
13
Ø Use WPA with Pre-Shared Key: type in 8 ~ 63 characters inside the dialog box to setup the
WPA password used between the AP and the clients.
Ø Use WPA with Radius Server: the authe ntication between the Radius Server, the AP and the
clients using the Group Key Re-key Settings.
No Rekeying: the clients will not need to re-key the password to authenticate with the Radius
Server.
Rekeying Time: Type in the time in minutes when clients will need to re-key the password for
authentication and security.
Rekeying packets: Type in the amount of packets that will be transmitted before clients will need
to re-key the password for authentication and security.
Ø Update Group Key: to update the password when the station or the client leaves the Networking
Group (BSS, Basic Service Set).
