RC4 algorithm/CRC

WEP basically uses a CRC of the frame payload plaintext in its encapsulation. The CRC is computed over the data payload and then appended to the payload before encryption. WEP then encrypts the CRC with the remaining data payload.The encryption scheme used in WEP involves generating an Initialization Vector.
