The lamp stayed lit for as long as the key was pressed, once the key was released, pressing the same key again would move the rotors and another lamp would light. This current is sent back through the rotors by a reflector and then it lights up a lamp in the lamp field representing the encrypted letter. The main parts are the keyboard, which moves the rotors, then applies a current through the rotors. The enigma machine was an electro-mechanical encryption device used around World War II. It can even be powered away from a computer by using a 9V battery and a barrel jack plug. Sure, a phone app is more practical, but this is a physical device can be interacted with, taken places, shown around and be a conversation piece. Once the touch screen shield has been mated to the arduino, it sort of resembles the actual machine.

Wouldn't it be something to have an Enigma simulator running in an arduino with a touchscreen.

For starters, set the rotors to D-A-D and configure the plugboard as shown above, and then type the characters displayed in the output panel to decrypt a secret message from me to you.I found an excellent Enigma simulator for the Android platform and this got me thinking.

You can try out the Enigma for yourself on Wintellect’s Web site, or you can download the source code and run it locally. The simulator uses animations to make the rotors turn, and it uses a MediaElement to play typewriter clicks. You can delete a cable by clicking it not yet implemented is the ability to grab one end of a cable and move it to another plug. You can use the up and down arrows above and below the rotor wheels to set the rotors to the desired position, and you can cable plugs together by clicking on an empty plug and dragging the cable that appears to another empty plug. Not visible, but included in the code, is a fourth, non-rotating wheel called a reflector. Our Enigma simulator features a keyboard, a plugboard, an output panel (replacing the 26 lamps), and three rotor wheels. Configure the rotors and plugboard differently and it could come out as GTUUK instead.

But an Enigma might encrypt the same phrase as YSKLW. A simple substitution cipher might encrypt AAAAA as NNNNN. Because input characters were transposed as they went through the wheels, the same letter would encrypt differently each time it was entered. The Enigma was a symmetric encryption/decryption device, meaning that an encrypted message could be decrypted by setting the machine to the same initial settings used to perform the encryption and typing in the encrypted message.Īs characters were typed on an Enigma, the rotor wheels would turn, odometer-style. A second operator would write down the encrypted message by recording the letters that lit up. (On its way back out, the character resulting from the encryption also went through the plugboard.) Finally, the operator would type the message, and each time a character was typed, one of 26 lamps, one for each character of the alphabet, would light. Connect B and C, for example, and a B typed on the keyboard was turned into a C before entering the encryption machinery. The purpose of the plugboard was to strengthen the encryption by swapping letters. Then they would configure the plugboard-the panel with the lettered and numbered jacks at the bottom of the screen-by cabling jacks together. To encrypt a message, Enigma operators would begin by loading the rotor wheels (represented by the three letters at the top of the screen) into the machine and setting them to a specific code-for example, A-B-C-taken from a code book. Historians estimate that cracking the code shortened the war by two years.

The story of how Polish mathematicians and researchers at Bletchley Park in the UK (including Alan Turing) cracked the Enigma code is both humbling and fascinating. There were many different versions of the Enigma our simulator models one of the 3-rotor devices. Here’s what it looks like:Įnigma machines were used to encrypt Axis military communications in World War II. Thursday is National History Day at our local high school, and just in time for the competition, my son and I put the finishing touches on a German Enigma simulator to complement his display-written, of course, in Silverlight.
