Fecha de publicación: | may-2009 | Editor: | Institute for Systems and Technologies of Information, Control and Communication | Citación: | Proceedings of the 7th International Workshop on Security Information Systems, WOSIS 2009, in conjunction with ICEIS 2009 | Serie: | pp. 16-25 | Resumen: | 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 improve- ment is based on cut sets de¯ned on some graphs so that only the most promising branches of the search tree have to be analyzed because cer- tain 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 be- forehand and avoided during search. | URI: | http://hdl.handle.net/10261/23778 | ISBN: | 978-989-8111-91-3 |
