Abstract

This paper analyses several sheets of schematic circuit diagrams and drawings of the US Navy Cryptanalytic Bombe which was used as part of the process of deciphering German Enigma encrypted messages. The functionality of selected circuits is verified through simulation and some circuits are analysed in-depth.
