WebRC4. RC4 is a stream cipher designed in 1987 by Ron Rivest for RSA Security. It is a variable key size stream cipher with byte-oriented operations. The algorithm is based on the use of … WebWEP shared key authentication uses the Rivest Cipher 4 (RC4) symmetric stream cipher to encrypt data; therefore, the same static key must be preconfigured on the server and clients. Both the encryption mechanism and cipher, however, are prone to security threats. The Wi-Fi Alliance developed WPA to overcome WEP defects.

RC4 was designed by Ron Rivest of RSA Security in 1987. While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" (see also RC2, RC5 and RC6).
