As an independent result, we improve Vaudenay’s analysis on Blowfish for reflectively weak keys. Moreover, we propose a new success criterion for an attack working on some subset of the key space when

J. Kraakits design criteria at all —, a non-trivial nine round byte characteristic can be established, which results in a possible attack of the modified .2 reduced to ten rounds without IT and FT, and reduced to nine rounds with IT and FT. Our analysis does not have a serious impact on the full .2, since i

Narrative

N. Weissenrieder,B. Stieram cipher mode of block ciphers, the basic summation generator, the shrinking generator, the clock-controlled cascade generator, and the modified linear congruential generators are analyzed. It generally appears that simple shift register based keystream generators are potentially vulnerable to line
