Invited talk: Breaking Enigma with the Bombe at Bletchley Park
Invited talk: Breaking Enigma with the Bombe at Bletchley Park
Dr. Dermot Turing
It is well-known that the British codebreakers at Bletchley Park used machinery, named the ‘Bombe’, to break into the Enigma cipher during World War 2. But, given that they did not even know the internal wiring of the Wehrmacht Enigma machine as late as July 1939, how did they develop the Bombe machine, and how did it work? What is the significance of the Bombe in the history of mechanised codebreaking?

Invited talk: Enigma in Action
Invited talk: Enigma in Action
Dr. Francesco Cosimato, and Sig. Flavio Atzeni
There are numerous studies on the Enigma machine, mostly focused on its operation, almost none on how it was actually used on the battlefield. Starting from this consideration, we conceived this Historical Workshop: "Enigma in Action", an in-depth look at the real-life use of the German cryptographic machine. From the transmission of a message actually sent during the Russian campaign to the forms used at the time.

Invited Talk: The History of Public Key Cryptography
Invited Talk: The History of Public Key Cryptography
Prof. Joachim Rosenthal
Public Key Cryptography was introduced through a publication by Diffie and Hellman 50 years ago. It became only much later clear that some government agencies knew the principles before. Since that time many good and many not so secure systems were introduced. In this talk we overview this development culminating in the search for post-quantum safe systems.
