Cryptanalysis of the Enigma Bletchley Park to describe the network that used the same Enigma setting sheets. Initially these were recorded using coloured pencils and were given the names "red", "light blue" etc., and later the names of birds such as "kestrel". During World War II the settings for most networks lasted for 24 hours, although towards the end of the war, some were changed more frequently. The sheets had columns specifying, for each day of the month, the rotors to be used and their positions, the ring positions and the plugboard connections. For security, the dates were in reverse chronological order down the
Technology during World War II II started. Equipment designed for communications and the interception of those communications became critical. The Germans widely relied on the Enigma coding machine for encrypting communications. The British developed a new method for decoding Enigma benefiting from information given to Britain by the Polish Cipher Bureau, which had been decoding early versions of Enigma before the war. Rocketry was used greatly in World War II. There were many different inventions and advances in rocketry, such as: The V-1, which is also known as the buzz bomb. This automatic aircraft is today known as a “cruise missile”. The V-1 was developed
