Problem 6.1 Does there exist any other distinguisher of complexity O(N)
involving the initial keystream bytes than the event (z

= 0)?
Problem 6.2 Investigate the existence of a long-term keystream bias of order

Problem 6.3 Can the existing biases be combined to create a bias greater
than the maximum of the biases?
N
, where the random association is also of order
