    Google artificial intelligence created its own encryption algorithm that nobody understands, so now the robot can do things in secret and nobody will know what it's doing. Great eh.

    Google AI invents its own cryptographic algorithm; no one knows how it works

    Neural networks seem good at devising crypto methods; less good at codebreaking.

    Google Brain has created two artificial intelligences that evolved their own cryptographic algorithm to protect their messages from a third AI, which was trying to evolve its own method to crack the AI-generated crypto. The study was a success: the first two AIs learnt how to communicate securely from scratch.

    The Google Brain team (which is based out in Mountain View and is separate from Deep Mind in London) started with three fairly vanilla neural networks called Alice, Bob, and Eve. Each neural network was given a very specific goal: Alice had to send a secure message to Bob; Bob had to try and decrypt the message; and Eve had to try and eavesdrop on the message and try to decrypt it. Alice and Bob have one advantage over Eve: they start with a shared secret key (i.e. this is symmetric encryption).


    Importantly, the AIs were not told how to encrypt stuff, or what crypto techniques to use: they were just given a loss function (a failure condition), and then they got on with it. In Eve's case, the loss function was very simple: the distance, measured in correct and incorrect bits, between Alice's original input plaintext and its guess. For Alice and Bob the loss function was a bit more complex: if Bob's guess (again measured in bits) was too far from the original input plaintext, it was a loss; for Alice, if Eve's guesses are better than random guessing, it's a loss. And thus an adversarial generative network (GAN) was created.

    Alice, Bob, and Eve all shared the same "mix and transform" neural network architecture, but they were initialised independently and had no connection other than Alice and Bob's shared key. For Alice the key and plaintext are input into the first layer of the neural network; for Bob the key and the ciphertext were input; and for Eve, she got just the ciphertext. The first layer is fully-connected, so the text and key can mix about. Following the first layer there are a number of convolutional layers, which learn to apply a function to the bits that were handed to it by the previous layer. They don't know what that function might be; they just learn as they go along. For Alice, the final layer spits out some ciphertext; Bob and Eve output what they hope is the plaintext.


    The results were... a mixed bag. Some runs were a complete flop, with Bob never able to reconstruct Alice's messages. Most of the time, Alice and Bob did manage to evolve a system where they could communicate with very few errors. In some tests, Eve showed an improvement over random guessing, but Alice and Bob then usually responded by improving their cryptography technique until Eve had no chance (see graph).

    The researchers didn't perform an exhaustive analysis of the encryption methods devised by Alice and Bob, but for one specific training run they observed that it was both key- and plaintext-dependent. "However, it is not simply XOR. In particular, the output values are often floating-point values other than 0 and 1," they said.


    In conclusion, the researchers—Martín Abadi and David G. Andersen—said that neural networks can indeed learn to protect their communications, just by telling Alice to value secrecy above all else—and importantly, that secrecy can be obtained without prescribing a certain set of cryptographic algorithms.


    There is more to cryptography than just symmetric encryption of data, though, and the researchers said that future work might look at steganography (concealing data within other media) and asymmetric (public-key) encryption. On whether Eve might ever become a decent adversary, the researchers said: "While it seems improbable that neural networks would become great at cryptanalysis, they may be quite effective in making sense of metadata and in traffic analysis."

    You can read the researchers' preprint paper on arXiv.

    Yeah, I was reading about this yesterday....... Im fully convinced we are actually living in the matrix. This shit is all too surreal.

    Especially the new generation. They take everything online really seriously. Social media and shit means their life, quite literally for some. Scary.

    So what do you think Google will call their variation of Bitcoin?

    "Google Bux" or "Bx", for short.

    I'm sure the US government is thrilled about this secret encryption... wonder if Google had to turn over the keys or not.

    I wonder if they will release a google bot that automatically learns internet marketing and works for you.

    Looks like the basic algorithm is not very complex but the machine has added so many steps to it, it became very very difficult to understand, and it produces fractional numbers and not whole numbers....this is scary on its own...I mean the damned robot created a encryption algo ...is it trying to hide stuff? Why?

    I think the real question here is what led the machine to do this. I sure hope Google has a mechanical electrical switch they can throw off and that is not controlled by the machine cuz if Google Brainz goes out of control, they should yank its power supply. I'm sure they've thought of this before they put the darned thing online(right Google?).

    Nothing to see here, just hyped up shit throw in a few buzz words and let the clowns do the rest.

    For the longst time now, my theory on what life is, is that the unviverse is trying to wake itself up. I don't fully comprehend what that means right now because I'm bound to think in these restricted ways in this vessel I findmyself in. However It might just be that AI taking over might be the next step. Having watched terminator 2 I understand that AI might obliterate us, but it might not be so.

    Just like a couple of hundrer years ago, a lot of people thought being gay was normal, yet it was so froundupon and accpeting gay culture was not nearly at a point it is right now. And thats the same principal this AI might think. Its thoughts on how to advance society might be so complex that people might not be ready to hear them right now.

    What if Google AI is gay?

    The two AI were set up to talk to each other and try to stop a third AI from listening. It's not that impressive... They pretty much forced it
