Decoding the Enigma with Recurrent Neural Networks
I am blown away by this -- given that Recurrent Neural Networks are Turing-complete, they can actually automate cryptanalysis given sufficient resources, at least to the degree of simulating the internal workings of the Enigma algorithm given plaintext, ciphertext and key:
The model needed to be very large to capture all the Enigma’s transformations. I had success with a single-celled LSTM model with 3000 hidden units. Training involved about a million steps of batched gradient descent: after a few days on a k40 GPU, I was getting 96-97% accuracy!

Enigma is a Linux based alternative to the default Spark operating system on these boxes. Enigma is a more customisable OS and provides the ability to add plugins which can accomplish many tasks enabling users to have a box which might look and perform like a Sky box, giving a 7 day EPG and an alternative to series link.


Looks like a pretty solid hacker community...
