In this paper we explore the intriguing factors involved in the non one-one nature of the RC4, and explore new techniques and present interesting findings regarding the same. The first part of this pa...
RC4 is the most widely used stream cipher around. A lot of modifications of RC4 cipher can be seen in open literature. Most of them enhance the secrecy of the cipher and the security levels have been ...
RC4+ stream cipher was proposed by Maitra et. al. at Indocrypt 2008. It was claimed by the authors that this new stream cipher is designed to overcome all the weaknesses reported on the alleged RC4 st...
The stream cipher RC4 was designed by R.Rivest in $1987$, and it is a widely deployed cipher. Many predictive states of RC4 for some special indices $i$ were presented in the last $20$ years. In this ...

RC4 has been the most popular stream cipher in the history of symmetric key cryptography till date. Its internal state contains a pseudo-random permutation over all $n$-bit words (typically $n = 8$) a...
