2.4 Authentication and
Security
The
Security
tab allows you to configure the authentication and encryption settings such as:
WEP, WPA, WPA-PSK. Each security option is described in detail below.
2.4.1 WEP Encryption
The
WEP
tab displays the WEP settings. Encryption is designed to make the data
transmission more secure. You may select 64 or 128-bit WEP (Wired Equivalent Privacy)
key to encrypt data (Default setting is Disable). WEP encrypts each frame transmitted from
the radio using one of the Keys from a panel. When you use WEP to communicate with
the other wireless clients, all the wireless devices in this network must have the same
encryption key or pass phrase. The following information is included in this tab, as the
image depicts below.
•
Authentication Type
: Select
Open
or
Shared
from the drop-down list.
•
Encryption
: Select
WEP
from the drop-down list.
•
WEP Key
: Type a character string into the field.
For 64-bit enter 5 alphanumeric or 10 hexadecimal characters.
For 128-bit enter 13 alphanumeric or 26 hexadecimal characters.

2.4.2 WPA, WPA2 Authentication & TKIP, AES Encryption
WPA (Wi-Fi Protected Access) was designed to improve upon the security features of
WEP (Wired Equivalent Privacy). The technology is designed to work with existing Wi-Fi
products that have been enabled with WEP. WPA provides improved data encryption
through the Temporal Integrity Protocol (TKIP), which scrambles the keys using a hashing
algorithm and by adding an integrity-checking feature which makes sure that keys haven’t
been tampered with. EAP (Extensible Authentication Protocol) is an extension to the PPP
protocol that enables a variety of authentication protocols to be used. It passes through
the exchange of authentication messages, allowing the authentication software stored in a
server to interact with its counterpart in the client.
