Abstract
With the advent of the 1920s people saw the need for a mechanical encryption device. Taking a substitution cipher and then rotating it was identified as an ideal solution. This idea had actually been used previously in a number of manual ciphers, but mechanization was able to make it far more efficient. The rotors could be implemented using wires and then encryption could be done mechanically using an electrical circuit.
