network. The 40bit and 64bit encryption are the same
because of out 64 bits, 40 bits are private. Conversely, 104
and 128 bit are the same. WEP uses a common KEY to
encode the data. Therefore, all devices on a wireless
network must use the same key and same type of
encryption. There are 2 methods for entering the KEY; one
is to enter a 16-bit HEX digit. Using this method, users must
enter a 10-digit number (for 64-bit) or 26-digit number (for
128-bit) in the KEY field. Users must select the same key
number for all devices. The other method is to enter a text
and let the computer generate the WEP key for
you. However, since each product use different method for
key generation, it might not work for different
products. Therefore, it is NOT recommended using.
WPA/WPA2: A security protocol for wireless networks that
builds on the basic foundations of WEP. It secures wireless
data transmission by using a key similar to WEP, but the
added strength of WPA is that the key changes dynamically.
The changing key makes it much more difficult for a hacker
to learn the key and gain access to the network.WPA2 is the
second generation of WPA security and provides a stronger
encryption mechanism through Advanced Encryption
Standard (AES), which is a requirement for some
government users.
