Puzzled: The Underlying Mathematics of the Enigma

04.04.2007 · Enigma Machine. This replication is accomplished using a program written in Java. In order to replicate the actual Enigma code, the components (namely the rotors) of the virtual encoder need to exactly match the ones used in the real machine. Although each rotor had its letters arranged

A predecessor of Enigma G was the "Zählwerk-Enigma" (A28), which was a commercial machine. Last not least, there were also custom-built models, such as a Swedish machine with 28-position rotors, and more exotic ones, like Enigma Z (Z30, "Numbers Enigma"), which had rotors with only ten positions (numbers 0..9) and was used to encrypt numerical ...

The Enigma machine on display at the Royal Naval Museum is a type M4 machine. It was probably used by the Norwegian Harbour Police, but is missing the reflector. The first rotor, therefore, has been adapted to enable it to do the reflector's job. This makes the machine an unusual specimen. A reading list for further information is available.
