The WEP has defenses against this attack. To avoid encrypting two cipher texts

with the same key stream, an Initialization Vector (IV) is used to augment the shared

WEP key (secret key) and produce a different RC4 key for each packet. The IV is also

included in the package. The WEP keys (secret key) are available in two types, 64-bits

and 128-bits. Many times you will see them referenced as 40-bits and 104-bits

instead. The reason for this misnomer is that the WEP key (40/104 bits) is

concatenated with the initialization vector (24 bits) resulting in a 64/128 bit total key

size.
