THE ENIGMA MACHINE 2
The Enigma machine
The Enigma machine was an ancient technological advancement for both the ease of use
for those who operated it and for the strength of the encipherment. It is an electro-mechanical
machine that resembles a typewriter, with a control panel to swap letters, a lamp to display the
results and rotors to scramble further the alphabets. Most models of the machine used 3 or 4
rotors with a reflector so as to allow the operators to use the same settings for deciphering and
enciphering (Ai, 2012).
Each of the rotors had a setting for the location. This was to enable the advancing
("odometer-style") of the wheel on the left. The rotors advance, the right rotor, advanced after
every letter enciphered, and at some setting on that rotor, it makde the middle rotor advance.
This would happen with all the 26 alphabetical letters (Cross, 2016). The rotor at the far left
advances at some setting of the rotor at the middle and then advances every 26 spinning of the
rotor at the center. This gives a message depth of 26X26X26 17,576, which implies that after
the message, different characters of information are enciphered, the encipherment repeats. Before
the location of the notch, it causes the turnover to occur eight characters. For example, if a rotor
has a notch in position D, the wheel on its left side would advance after going beyond V, and the
notch on the rotor at the left side has no effect. The rotors were used to perform various
permutations. The following table shows that different permutations performed by the rotors.
