The stream cipher RC4 has been analyzed by using various schemes since the algorithm was leaked
in 1994.In particular, for key recovery attack assuming known keystream there are two important key-correlation
equations found by Vaudenay et al. in 2007 and Maitra et al. in 2008. In this paper, we present third correla-
tion between keystream and secret key. This correlation hold with approximately 1.045/N at most and continue
until 140th keystream byte . Furthermore, this equation includes keylength-dependent biases found by Isobe et
al. in 2013. It is weaker than two existing correlations, we show and consider the new correlation which had been
overlooked more than twenty years. |
