History of Enigma through Codemaking and Codebreaking in WWII


Tuesday August 22, 2017

    2:00 PM



    3:00 PM


In this very special guest lecture, Richard Brisson will present the History of Enigma through Codemaking and Codebreaking in WWII -together with a cursory glance at the Dieppe Raid Hypothesis.

This lecture has been arranged in order to mark the 75th anniversary of the Dieppe Raid (August 19th, 1942).

As part of investigating the history of Enigma, Brisson will cover important design concepts of the Enigma (Codemaking) along with its cryptanalysis, weaknesses and eventual exploitation (codebreaking). Enigma’s origins are rooted in the 1920’s while being adopted by Germany for securing government and military information in the early 1930’s – during those 1930’s, Polish mathematicians were able to unravel and break Enigma enciphered messages as used by the German military. A key portion of the presentation will focus on the accomplishments at Bletchley Park in order to achieve exploitation of Enigma, especially the version by the German Navy (Kriegsmarine) and its so-called wolfpacks in the Atlantic. Brisson will also investigate the hypothesis that the Dieppe Raid was used as a cover for recovering Kriegsmarine Enigma secrets.
