Crypto Homepage --> Cipher Machines Challenge
The Hebern machine is the first cipher device to introduce an electrical circuitry and rotors. Unfortunately, its inventor, Edward Hebern, would never be rewarded to this in his lifetime.
The key to the Hebern design was a disk with electrical contacts on either side, known today as a rotor. Linking the contacts on either side of the rotor were wires, with each letter on one side being wired to another on the far side in a random fashion. The wiring encoded a single substitution alphabet.
Note: I wrote a web page regarding Hebern's cipher machines. I describe their history, their functioning and even their cryptanalysis (link).
