... random bits of data known as a keystream. These pseudorandom bits are equal in length to the plaintext data that is to be encrypted. The pseudorandom bits in the keystream are then combined with the plaintext data bits by using a Boolean XOR process. The end result is the WEP ciphertext, which is th ...

... Layer to counter the issues related to wired equivalent privacy (WEP). The existing 802.11 standard specifies the use of relatively weak, static encryption keys without any form of key distribution management. This makes it possible for hackers to access and decipher WEPencrypted data on your WLAN. ...
