Enigma Cryptanalysis Revisited – New State-of-the-Art Attacks on the Enigma Machine in CrypTool 2

#cryptology, #cryptography, #cryptanalysis

In this video, we show our newly implemented state-of-the-art attacks on the Enigma rotor cipher machine. The attacks are right now (at the time of creating this video) only available in the current nightly build of CrypTool 2. It will be available also in the next release version of CrypTool 2.

We recently got some criticism that our (old) Enigma analysis was not state-of-the-art. That was true, since the attacks were 10 years old. Therefore, we developed a new Enigma analyzer based on George Lasry's code.

We implemented the following new attacks:
- Turing Bombe
- Hillclimbing
- Simulated Annealing

Also, to have a faster attack, we implemented an attack based on Jim Gillogly's original paper.
