Talking about Poland’s contribution to the Allies in World War II, apart from being on the battlefield, many guests mentioned that before the start of World War II, Poland laid the foundation for the final victory of the Allies. This is the Polish deciphering the German Enigma code. Pioneering work is done.

In 2014, with the release of the movie “Imitation Game”, the British mathematician Alan Turing, known as the “father of computer science”, began to receive public attention. The film mainly talked about Turing’s assistance to the Allies to decipher Enigma. The password, thus reversing the legendary experience of the Second World War. But because the film attributed Enigma’s deciphering to Turing, it also caused a lot of controversies.

As early as 1921, the Poles received a commercial Enigma cipher from the Germans, three outstanding graduates of the Poznan Institute of Mathematics, Marian Reyevsky, Gertz Rozki, and Henrik Zogarsky began to study its principles and tried to decipher.

Of course, the military Enigma cipher machine is more complicated than the commercial machine. The Polish wants to decipher it and must touch the actual machine. Fortunately, Hans Tillow Schmidt, who worked in the German Defense Password Office, handed the French intelligence agency a cryptographic machine manual and a button from September to October 1932. The instructions were set and the Frenchman handed it over to Poland.

At the end of 1932, the Poles had already derived the internal workings of the military Enigma cipher. Subsequently, the Polish company began to copy the Enigma cipher machine. At the end of 1938, the Poles also invented a cryptograph called Bombe, mechanized to simulate the encryption process, which is equivalent to the cooperation of six Enigma cipher machines. The “bombe” machine can find the key of the day within 2 hours, which can save hundreds of people’s manual work.

And for the German, the most significant mistake of them is that they even don’t know the machines and the ciphers were spread to the other countries, and the cipher the German used in WWll, were too similar to the cipher they used in the Wwl. This also provides many chances and helps to the Allies. And before the German-occupied the Polan, the Poles already give the Bombe machine to the British, this also helps Turing to further decipher the German cipher.
