A machine rotor represents the rotating assembly within a larger mechanical or electrical system, serving as the primary component for energy conversion or transfer.

Learn about the rotor machine and study its components. Explore the uses of cipher machines, history of the rotor machine, and examples of cipher equipment.

The basic principle of the rotor machine is illustrated in Figure 2.8. The machine consists of a set of independently rotating cylinders through which electri-cal pulses can flow.

To mechanize the production of ciphertext, a family of devices called rotor machines was invented, which implement Vigenere ciphers with long periods.
