Binary Decision Diagram (in short BDD) is an efficient data structure which has been used widely in computer science and engineering. BDD-based attack in key stream cryptanalysis is one of the best forms of attack in its category. In this paper, we propose a new key stream attack which is based on ZDD(Zero-suppressed BDD). We show how a ZDD-based key stream attack is more efficient in time and ...

These dimensions are interrelated and interacting, but irreducible to each other, and have had different historical trajectories, within and between nations. Over the last half-century, the contrast between advances of existential equaliz...
