Although the machine was originally meant to be used to transmit confidential business-related information, but in the late 1930s, its unmatched potential as a transmission device in the theater of warfare was realized.As mentioned earlier, the Enigma Machine is an electromechanical device, which works through mechanical parts as an electric current passes through it.The machine consists of four main components: the keyboard, plugboard, lampboard and rotors. Therefore, when the letter ‘L’ is pressed, the fast rotor rotates one notch, changing the number in the gauge next to it.

Enter the first letter of your message on the keyboard and a letter lights up showing what it has replaced within the encrypted message. Therefore, after going through the entire circuit, if the letter ‘L’ is encrypted as ‘A’, then the light beneath the ‘A’ is lit.Does all this talk about the Enigma Machine make you want to make your own Enigma code? ENIGMA was a cipher machine—each keystroke replaced a character in the message with another character determined by the machine’s rotor settings and wiring arrangements that were previously established between the sender and the receiver. But the final steps were always performed manually: the job of the Bombe was merely to reduce the number of combinations that the cryptanalysts had to examine.Even as the Allied code-breaking team were working on Enigma, the Axis was improving its machines, adding more and different rotors, and minimising operator error. It takes a letter as an input and reflects a different letter as an output. This greatly increases the number of possible encoding configurations. Before Rejewski started work on the Enigma, the French had a spy, Hans-Thilo Schmidt, who worked at Germany's Cipher Office in Berlin and had access to some Enigma documents. It was then down to the codebreakers to use the knowledge provided by the Bombe and figure out the rest of the key.Once the code was cracked, the workers at Bletchley Park could set up an Enigma machine with the correct key for the day and reverse the code for every message intercepted on that day.Once the Enigma machine was cracked, 211 Bombe machines were built and ran around the clock.

Fully deciphered messages were then translated from German to English before being passed on to British intelligence.At its peak, the Bombe was able to help crack 3,000 German messages per day. The Bombe machine would try to determine the settings of the rotors and the plugboard of the Enigma machine used to send a given coded message.The standard British Bombe machine was essentially 36 Enigma machines wired together, this way, the Bombe machine would simulate several Enigma machines at once. Each time a key is pressed on an Enigma machine, the rotors turn, and the code changes.

When 60 moves of the second hand are complete, the minute hand moves one notch; similarly when 60 moves of the minute hand are complete, the hour hand moves one notch.After the signal comes out as an output from the slow rotor (left rotor), it goes through the reflector. So if the "K" key is pressed, and the Enigma machine encodes that letter as a "P," the "P" would light up on the lamp board.Each month, Enigma operators received codebooks which specified which settings the machine would use each day.

There have been many such examples when, despite being on the defense for a long time, a sudden breakthrough with the help of sheer intelligence helps to turn the tables. Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing For additional security, the German military services usually double-encrypted their messages by first substituting original text with code words … If any contradictions arose, say, it deduced that “A was connected to W,” then it must be that A is not connected to Z on the plugboard, a contradiction arises. It was meant to be a cipher device that would help in the transmission and reception of classified messages in the political and business domain. If you couldn’t gauge its complexity, then let me help you out.For a single encoded message, there are a total of.For a normal human being working without the aid of machines, it would take hundreds of years to go through all these possible settings, and there would still be no guarantee of success.
