In this paper, we focus on a keystream of RC4 PRGA. The analysis of the transitions of two permutations, S and S′,
with some differences in the initial round were argued in [5] [17] [18]. Recently the existence of colliding keys was shown theoretically
in [8] even if a secret key length is short. In addition, the existence of pairs of the secret key that generate two permutations, S and
S′, with two bytes differences in the initial round was shown theoretically. In this paper, we investigate how the structure mixes the
permutation S by observing correlation between two keystream Z and Z′ which are generated by two permutations, S and S’, with some
differences in the initial round. We show that we can suppose the part of the initial permutation with the probability that is higher
than the random. |
