Two researchers have introduced new techniques for breaking Enigma messages. Using these techniques they have deciphered hitherto unsolved Enigma cryptograms from World War II.
The Reihenschieber was a simple encryption device used by the Germans in the Cold War. I built a model of it with Lego bricks. Can you solve an encrypted text I produced with it?
Just like every end of year, I am awarding the Golden Alice for outstanding achievements in the field of crypto history.
Enigmas are getting more and more expensive. In New York, a four rotor naval Enigma has now sold for almost half a million dollars.
