WebHistory. 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). RC4 was initially a trade secret, but in September 1994, a description of it was anonymously posted to the Cypherpunks mailing list. It was soon … WebTo secure WLAN for data transmission, RC4 algorithm is able to provide the advantages of fast performance in the resource constrained environment. This paper analyzes the security ofRC4 algorithm, presents a way to enhance the security of RC4 algorithm and analysis the affection of the enhanced algorithm by using MD5/hash function.
