Do you mean this one? Marian Rejewski An Application of the Theory of Permutations in Breaking the Enigma Cipher http://www.impan.pl/Great/Rejewski/article.html Since I write again about this, I need to point out the role of French. Their German agent, working inside German cryptographic dept, Hans-Thilo Schmidt [1], gave back plenty of materials, including operating procedures and manuals. Those in turn were given to British and Polish cryptographers. French and Britons gave up, however. In Poland, the new materials contributed towards solving equations which Rejewski used to describe E*'s operation. Also, I am under impression that during the war, our cooperation with the French much more resembled a partnership. As compared to cooperation with other Allies. No whining, just an observation. Also, I may be prejudiced and wrong, maybe later I find out some new info and will change opinion (again). There are other aspects of all this, like Polish network in Africa (mostly northern, I think). I have barely scratched the subject. Actually, I am just a lowest form of hobbyist, a reader of blogs :-). Anyway, I am yet to see a movie as interesting as those real life stories. If I wanted to wait, it would have been a long wait. -- [1] Schmidt was arrested by Germans in 1943 and months later committed suicide in prison. -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.
