Wireless Security Encryption

WEP uses a secret key shared between the wireless user and the access
point so the all data transmitted and received between the wireless station
and the access point may be encrypted using this same shared key.
802.11 permits the use of an established secret key unique to each wireless
user. In the majority of cases, one key is shared throughout all
users and access points on the WLAN.

Encryption is comprised of the secret key and an RC4 pseudorandom
number generator. Normal data is first encrypted and then protected
against unauthorized modification while it moves across the network.

The secret key is transformed into the final shared key that is inserted
into the pseudorandom number generator (PRNG).
