RC4 Encryption Algorithm
The RC4 Encryption Algorithm, developed by Ronald Rivest of RSA, is a shared key stream cipher algorithm requiring a secure exchange of a shared key. The symmetric key algorithm is used identically for encryption and decryption such that the data stream is simply XORed with the generated key sequence. The algorithm is serial as it requires successive exchanges of state entries based on the key sequence. Hence implementations can be very computationally intensive.
The RC4 encryption algorithm is used by standards such as IEEE 802.11 within WEP (Wireless Encryption Protocol) using 40 and 128-bit keys. Published procedures exist for cracking the security measures as implemented in WEP.

it is used in WEP and TKIP
TKIP is better than WEP, but it uses RC4 to allow compatibility with older devices that had only WEP characteristics.
