Abstract

A new graph-based approach to edit distance cryptanalysis of some clock-controlled generators is here presented in order to simplify search trees of the original attacks. In particular, the proposed improvement is based on cut sets defined on some graphs so that only the most promising branches of the search tree have to be analyzed because certain shortest paths provide the edit distances. The strongest aspects of the proposal are: a) the obtained results from the attack are absolutely deterministic and b) many inconsistent initial states are recognized beforehand and avoided during search.
