As the old ancestor of programmers, Turing, everyone should have heard more or less. But I still want to give you a brief introduction: Turing's cipher story begins with a "mystery", which is a cipher used during the war, and it was Turing who cracked this cipher. During World War II, Germany invented a seemingly unbreakable cipher "ENIGMA", a machine for ENIGMA encryption and decryption. This cipher was widely used by the German army, including locating submarines on the Atlantic transport line. These submarines sank British ships with frightening speed in what Churchill dubbed the "Battle of the Atlantic." Churchill feared that the British would be defeated by a shortage of supplies, and the only solution was to stop the German submarine tactics, and cracking ENIGMA was one of the ways to stop the Germans. If the British could decipher the intelligence, they could locate and destroy the submarine. But for a full 13 years, both the British and the French considered ENIGMA to be indecipherable. In response to this situation, the government established a new institution, the British Government Cryptography School. This problem was also handed over to Turing, who since September 1938 has been in charge of the cryptanalysis of ENIGMA. He led the cryptanalysis of some 200+ talented people, including even world chess champion Alexander. The work of analysis and calculation is so complex that 26 letters can replace 8 trillion puzzle letters in the "ENIGMA" machine. If you change the wiring, the change is more than 2.5 quadrillion. Turing relied on his genius to design a deciphering machine. This machine is mainly composed of relays, and also uses 80 electron tubes. The password is directly read by a photoelectric reader, and it can read 2,000 characters per second, which is called "Turing bomb". ~~~~~~~ After watching this movie, I am really sad for Turing's arrival, but how can I say it, it can only be said that his success was also in that era, and his defeat was also due to that era~~~~~~ ~~
