Lorenz SZ40/42Edit

The Lorenz SZ 40 and SZ 42 (Schlüsselzusatz, meaning "cipher attachment") (Wikipedia) were German cipher machines used during World War II for teleprinter circuits. British codebreakers termed the machine and its traffic "Tunny".


The M-209 (Wikipedia), designated CSP-1500 by the US Navy, is a portable, mechanical cipher machine used by the US military primarily in World War II, though it remained in active use through the Korean War. The M-209 was designed by Swedish cryptographer Boris Hagelin. M-209's can be found at:


The NEMA (Wikipedia) (NEue MAschine) ("new machine"), also designated the T-D (Tasten-Druecker-Maschine) ("key-stroke machine"), was a 10-wheel rotor machine designed by the Swiss Army during World War II as a replacement for their Enigma machines.


SIGSALY (Wikipedia) was a telephone scrambler used in World War II for the highest-level Allied communications. The machine also pioneered digital communications, including the first transmission of speech using pulse code modulation.

  • The National Cryptologic Museum, Maryland, US — a mockup of part of a SIGSALY terminal.
  • Cabinet War Rooms, London, UK. The museum contains the Transatlantic Telephone Room (a converted broom-cupboard) where Winston Churchill was able to connect to a SIGSALY installation for secure transatlantic communications [2]; the actual SIGSALY machine was located elsewhere.
