Enigma-E―A fully operational electronic Enigma machine

摘要

On a recent trip to Bletchley Park I was introduced to Marc Simons and Paul Reuvers from Holland. They had with them a kit of parts that, with a little care and time, transforms into exactly what it says on the box - a fully operational electronic Enigma machine. The German Enigma is perhaps the best known of many mechanical cipher systems developed during the 20th century. The Enigma was produced by Dr Arthur Scherbius's company Chiffriermaschinen Aktien Gesellschaft of Steglitzerstrasse 2, Berlin, in 3923 as a commercial machine. Commercial Enigma machines? Oh yes, the Enigma was originally intended as a cipher machine for commercial use by banks, insurance companies - for any company that needed security for its business messages.
