Problem 5.1 Does there exist any cycle in real RC4 states?
Problem 5.2 Apart from Finney cycle, does there exist any other cycle in the
state space of RC4 corresponding to different initialization conditions?
Problem 5.3 Recall the conditional bias of z
1
toward K[2]+ 3 (given K[0]+
K[1] = 0) in Theorem 5.5.4. Can similar strong conditional biases be
present in subsequent keystream bytes?
