Enigma Machines - Stephen Peek

The Enigma Enciphering Machine was invented in 1918 by German engineer Arthur Scherbius. It’s an electrical Morse code-producing device that used a keyboard, lamps and a set of rotors to scramble text, then send it out to a receiving machine whose rotors were set in the exact same way as the originating machine’s. Enigma first went into production in the early 1920s and was used for civilian applications such as the protection of corporate trade secrets and private communications.

If the PIC Enigma Machine doesn't detect a AT/XT keyboard, then kb will be displayed.

The 7x5 dot matrix displays are red, which is not shown very clearly in the pictures or video.

Components needed for this project:

4.5v (No voltage Regulator needed)

1x - PIC16F628A

1x - PIC 18-Pin Socket

1x - PS/2 Mini Connector

1x - 7x5 Dot Matrix Display

5x - 100ohms (Brown, Black, Brown, Gold)

1x - Disk Capacitor 100nF

You will also need the following if using a 9v Battery

2x Electrolytic Capacitor 10uF 16v

1x - 5v Voltage Regulator 78L05

Wireless Arduino Enigma Machines

1. Top right - German Army Field Enigma Machine

(Transmitting ciphertext using daily settings)

2. Top left - German Army Headquarters Enigma Machine

(Receiving ciphertext & decoding using daily settings)

3. Bottom - Bletchley Park Codebreakers

(Receiving ciphertext by wireless intercept stations)

After interception, the encrypted messages were sent to Bletchley Park to be decrypted.

When you type on the keyboard the top right (German army field Enigma Machine) displays the plaintext and using the daily settings below decodes the message into ciphertext. The message is then transmitted using Morse Code.

Daily Settings

Reflector: B

Rotor Order: 1 2 3

Ring Start Setting: A A A

Rotor Start Setting: A A A

German Army headquarters Enigma Machine (top right) receives the ciphertext and using the daily settings decodes the message back into plaintext.

'Y' service (wireless intercept stations) United Kingdom.

After interception the ciphertext messages would be taken to Bletchley Park Codebreakers for analysis, and using the Bombe to retrieve the daily settings for the Enigma Machine.

German Army Field Enigma Machines

S: = Rotor Start Position (AAA) P: = Plaintext

R: = Rotor Order (123) C: = Ciphertext

German Army Headquarters Enigma Machines

S: = Rotor Start Position (AAA) C: = Ciphertext

R: = Rotor Order (123) P: = Plaintext

Bletchley Park Codebreakers

C: = Ciphertext

DS: = Daily Settings (B 123 AAA ???)

Programming the Arduino with the settings:

Reflector: B

Rotor Order: 1 2 3

Ring Start Setting: A A A

Rotor Start Setting: ? ? ?

After time, the Arduino will decipher the correct Rotor Start Settings, however.... trying to decipher the correct Ring Start Setting & Rotor Start Setting is proving a problem!

Enigma Machine

The German Navy began to use it in 1926, but it was the German Army who in 1928 created a version distinctly different from the commercial machine. They added a plugboard which swapped pairs of letters and vastly increased the encipherment permutations.
