WPA Encryption
Use this field to select the encryption method used to encrypt data when WPA encryp-
tion is enabled. The default method is Temporal Key Integrity Protocol. (TKIP--formerly
WEP-2)
WPA Pre-Shared Key
Use this field to select the WPA pre-shared key when WPA encryption is enabled. The
pre-shared key should be between 7 and 64 characters. If this field is left blank, a value
of 00000000 will be assigned by the system.
WEP Encryption
The IEEE 802.11b standard specifies an optional encryption feature, known as Wired
Equivalent Privacy (WEP) that is designed to provide a wireless LAN with a security
level equal to what is found on a wired Ethernet network.
WEP encrypts the data portion of each packet exchanged on the 802.11b/g network
using either a 64-bit or 128-bit encryption algorithm. In addition, WEP is also used in
conjunction with the optional Shared Key Authentication algorithm to prevent unautho-
rized devices from associating with an 802.11b/g network.
Enabling WEP can protect your data from eavesdroppers. The Terayon WX-54G sup-
ports both 64-bit and 128-bit encryption algorithms. Select the type of encryption you
want to use (64 or 128 bit) and configure one to four WEP Keys along with setting the
"Default Key" to one of the keys. The "128-bit" method is considerably more secure than
the "64-bit".
If you do not need this feature, select "None" to prevent setting the keys.
Passphrase
Enter a passphrase to automatically generate four WEP keys. A WEP key is either 10 or
26 hexadecimal digits (0~9, a~f, and A~F) depending on whether you selected 64 bit or
128 bit in the WEP pull-down menu. Type a combination of up to 64 letters, numbers, or
symbols in the Passphrase field. The Terayon WX-54G Manager uses an algorithm to
generate four WEP keys for encryption. If you want to type in the keys manually, leave
this field blank.
The Terayon wireless family of products all use the same algorithm. Therefore the same
phrase can be used to generate the same WEP keys for all devices.
The Passphrase feature is provided to easily generate WEP keys; however, this is not
as secure as manual assignment.
