14 de ago. de 2019 · “This plaque commemorates the work of Marian Rejewski, Jerzy Rozycki and Henryk Zygalski – mathematicians of the Polish intelligence service – in first breaking the Enigma code. Their work greatly assisted the Bletchley part code-breakers and contributed to the Allied victory in World War Two.”
The Zygalski-sheet apparatus takes its name from Polish Cipher Bureau mathematician – cryptologist Henryk Zygalski, who invented it about October 1938. Method. Zygalski's device comprised a set of 26 perforated sheets for each of the, initially, six possible sequences for inserting the three rotors into the Enigma machine 's scrambler. [1] .
Zygalski sheets, developed by Polish codebreaker and mathematician Henryk Zygalski in 1938, were a manual grid-based cardboard system used by the Polish Cipher Bureau and Bletchley Park to aid the decryption of German Enigma machine cipher messages.
Marian Rejewski, Jerzy Rozycki, and Henryk Zygalski pains-takingly analyzed the intercepted encrypted messages searching for clues. Rejewski eventually determined a mathematical equation that could find the wiring connections. However, the equation had too many unknown variables. He finally made the initial breaks into the wiring sequence only with
