ABSTRACT Victory was the name of the first prototype Bombe that was developed for breaking the German Enigma messages of World War II. It lacked the diagonal board and simultaneous scanning that was provided for all the later models, but these disadvantages were overcome by the ingenious use of a column menu (a special Bombe menu where the Enigma fast rotors are all in the same position) to break six days of naval traffic, 22–27 April 1940, following the pinch of material from an armed trawler…

History and Modern Cryptanalysis of Enigma's Pluggable Reflector
The development history of Umkehrwalze Dora, Enigma's pluggable reflector, is presented from the first ideas in the mid-1920s to the last development plans and its actual usage in 1945, when it was intercepted by the British.
Turing’s anticipation of empirical bayes in connection with the cryptanalysis of the naval enigma
The Enigma was a cryptographic (enciphering) machine used by the German military during WWII. The German navy changed part of the Enigma keys every other day. One of the important cryptanalytic
A recursive solution for Turing’s H-M factor
This article derives the H-M factor using a recursive technique for both the standard Bombe and the Jumbo Bombe, a later version incorporating the machine gun mechanism.
