    Tim Sweeney Retweeted myk is teetering

    The modern world is built on cryptographic security, which relies on one-way functions. But nobody has proven that one-way functions exist. Perhaps they don’t. https://en.m.wikipedia.org/wiki/One-way_function …https://twitter.com/mykola/status/1198719315589160960 …

    Tim Sweeney added,

    myk is teetering @mykola
    Please quote this tweet with a thing that everyone in your field knows and nobody in your industry talks about because it would lead to general chaos.

        As with most security, “hard” (not impossible) is good enough. A proof would imply we found an impossible to reverse one-way function.

        "hard" is what is not proven. We think we have such functions and use them. but it's possible there is actually a (computationally) easy way to reverse them that we just don't know yet. Even worse such functions might not even exist.

        They don't exist. They just require more energy than the sun has in order to calculate the reverse. https://en.m.wikipedia.org/wiki/NP-hardness …

        And I wouldn't call them one way functions, they're usually referred to as factorable functions, like exponential functions dealing with sums and products.
