摘要:Cryptanalysis of ciphers is a technique used to find flaws in the cryptographic algorithm and try to overcome these flaws to give much better security. There are many cryptographic algorithms such as DES, AES, RSA etc. Rc4 is a stream cipher that is used on a large scale in wireless networks and IEEE standards. Many attacks have been tried over RC4. In this paper we will see what is RC4, how encryption is done, a differential attack on rc4 and a method or the changes required to the cryptographic algorithm to secure this cryptographic algorithm against differential attack.
