Encryption
• All users throughout the Internet can read unencrypted data, illustrated below
with a simple wired network.
• B want to send some data to A, but the data was intercepted by C.
• C then modifies the data and transmits it to A. A is unaware of C’s presents
and thinks the data originates from B.
With wireless networks, data is even more vulnerable to such attacks since
everyone within your radio transmitting range can intercept your data.
Wired Equivalent Privacy (WEP) provides techniques to prevent intruders invading
your data.
With the current IEEE specification, WEP encryption has two types, 64 and 128
bits

encryption.

Other manual may specify 40 or 104bits encryption, this is because the manual didn’t include 24 bits Initialization
