If plain text is entered, the lit-up letters are the encoded ciphertext. In typical use, one person enters text on the Enigma's keyboard and another person writes down which of 26 lights above the keyboard lights up at each key press. This Numberphile Video has a demonstrations of the gears and plugboard of the Enigma, and some explanation of combinations.Enigma has an electromechanical rotor mechanism that scrambles the 26 letters of the alphabet. Good student reading, with guiding questions. Here are some sites with additional information relating to the Engima:Įxploring the Enigma, from +Plus Magazine. The Enigma machine is its own INVERSE! How exciting is that! How many ideas or devices do we know of which are their own inverse? Then this coded message is typed, using the same rotor settings, and we get back the original message.

A message is coded using a rotor setting.

Are there any patterns we can use to help decode the message? Any predictable behavior?.

After looking at some messages and their coded outputs, is there a ONE-TO-ONE correspondance here? For example, does the letter E in a coded message always map to the same decoded output letter?.

And I want you to be successful! Set those pesky rotors to R-J-L (my initials), and start typing! You can also copy and paste the message, but it is far more fun to watch the rotors do their work as you type.Įmbedded in all of this crypography history are some neat math discussions:

Working through this issue was the task of many of the mathematicians during WWII. If they aren’t set correctly, then the machine is of little help. So, now you have everything you need to decode my message it seems.

But here’s the neat thing about the Enigma machine: the machine is used to both code AND decode messages, using similar procedures, which are outlind here. You can try your hand with some coding using this Enigma Simulator, which shows the coding rotors, inputs and outputs. How would you even start to decode this message? Does a one-to-one correspondance seem reasonable? How else can letters be coded? There were a number of variations of the machine over the war years, and the Allied forces employed many mathematicians, many working through Blechtley Park in London, to intrcept and de-code messages. The electric signals from the keyboard passed through a system of rotors and plugs, and lit up a letter, which was recorded. Messages were typed using a standard keyboard.

The Engima machine is a coding machine, used primarily during World War II, to both code and decode messages.

One of the first artifacts we encountered in the exhibit was the Enigma machine shown below, which I fawned over like a teenage girl at a One Direction concert. More info on this challenge below.Ī trip today to the Franklin Institute science museum in philadelphia reminded me some of cryptography nuggets you can use in math class in particular, discussion starters for inverses, and code-breaking using matrices. Here is a challenge which has appeared on my classroom board, in various forms, over the past 10 years:Ĭan you decode the message? In 10 years, I have given out zero gift cards….so good luck.
