128-Bit WEP
As a result of 64-bit WEP's potential security weaknesses, a more
secure method of 128-bit encryption was developed . 128-bit encryption
includes a key length of 104 bits plus 24 additional bits of system-
generated data (128 bits total) . Some hardware manufacturers refer to
128-bit as 104-bit encryption .
Most of the new wireless equipment in the market today supports both
64-bit and 128-bit WEP encryption, but you might have older equipment
that only supports 64-bit WEP . All Belkin wireless products will support
both 64-bit and 128-bit WEP .
Encryption Keys
After selecting either the 64-bit or 128-bit WEP encryption mode, it is
critical that you generate an encryption key. If the encryption key is not
consistent throughout the entire wireless network, your wireless networking
devices will be unable to communicate with one another on your network
and you will not be able to successfully communicate within your network .
You can enter your key by typing in the hex key manually, or you can
type a passphrase in the "Passphrase" field and click "Apply Changes"
to create a key . A hex (hexadecimal) key is a combination of numbers
and letters from A–F and 0–9 . For 64-bit WEP, you need to enter 10 hex
keys . For 128-bit WEP, you need to enter 26 hex keys .
For instance:
AF 0F 4B C3 D4 = 64-bit WEP key
C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit WEP key
Wi-Fi Protected Access
WPA is a new Wi-Fi standard that was designed to improve upon the
security features of WEP . To use WPA security, the drivers and software of
your wireless equipment must be upgraded to support WPA . These updates
will be found on the wireless vendor's website . There are two types of WPA
security: WPA-PSK and WPA2 .
WPA-PSK
uses what is known as a pre-shared key as the network
key . A network key is basically a password that is between eight and
63 characters long. It can be a combination of letters, numbers, or
characters . Each client uses the same network key to access the network .
Typically, this is the mode that will be used in a home environment .
WPA2
™ requires Advanced Encryption Standard (AES) for encryption
of data, which offers much greater security than WPA . WPA uses both
Temporal Key Integrity Protocol (TKIP) and (AES) for encryption.
