Wikipedia has this to say on the matter:<br /><br />“The spies that it placed in enemy countries used a lower level cipher (which was broken by Oliver Strachey's section at Bletchley Park) for their transmissions. However, the messages were often then re-transmitted word-for-word on the Abwehr's internal Enigma networks, which gave the best possible crib for deciphering that day's indicator setting.”kesler12https://www.blogger.com/profile/06730943788519488679noreply@blogger.comtag:blogger.com,1999:blog-3335175720102608134.post-87576082302834827302017-06-25T22:20:37.475-07:002017-06-25T22:20:37.475-07:00I’m not an expert but it seems that the use of a p...I’m not an expert but it seems that the use of a plugboard together with the irregular stepping system of the Enigma G would have been very hard to solve, at least with WWII technology.<br /><br />From the article it seems that the biggest mistake was enciphering the message key twice on the basic setting. This procedure was used by the German Army till May 1940 (double indicators, not on a basic setting though) and it allowed the British codebreakers to solve Enigma traffic. <br /><br />The basis of the solution is that the 1st and 5th, 2nd and 6th 3rd and 7th, 4th and 8th letters of the indicator represent the same initial letters (the example is for the Enigma G when the indicator had 8 letters).<br /><br />Also having a basic setting (grundstellung) was a mistake (shared by the German Navy!). <br />Christos T.https://www.blogger.com/profile/04246906263926130737noreply@blogger.comtag:blogger.com,1999:blog-3335175720102608134.post-86667574362711197212017-06-25T19:01:54.306-07:002017-06-25T19:01:54.306-07:00If the abwehr enigma had been given a set of 5 rot...If the abwehr enigma had been given a set of 5 rotors (instead of 3), AND had used a plugboard, would it have been categorically superior to other enigma models? The extra notches and more frequent stepping seems to be a big advantage. Would the allys have been able to crack it at all?<br /><br />Come to think of it, what operational mistakes by the abwehr led to their enigma model being broken at all?kesler12https://www.blogger.com/profile/06730943788519488679noreply@blogger.com
