Chinese Prof Cracks SHA-1 Data Encryption Scheme

Hades1010 writes to mention an article in the Epoch Times (a Chinese newspaper) about a brilliant Chinese professor who has cracked her fifth encryption scheme in ten years. This one's a doozy, too: she and her team have taken out the SHA-1 scheme, which includes the (highly thought of) MD5 algorithm. As a result, the U.S. government and major corporations will cease using the scheme within the next few years. From the article: " These two main algorithms are currently the crucial technology that electronic signatures and many other password securities use throughout the international community. They are widely used in banking, securities, and e-commerce. SHA-1 has been recognized as the cornerstone for modern Internet security. According to the article, in the early stages of Wang's research, there were other data encryption researchers who tried to crack it. However, none of them succeeded. This is why in 15 years Hash research had become the domain of hopeless research in many scientists' minds. "

    And what does a professor at your local university gain from having tenure and sitting on his ass all day without doing anything (teaching 2 classes a week doesn't count as "doing something"), getting paid $70k, without the possibility of ever being fired until the day he dies...?


    Here is a professor that actually does something and everyone is amazed - "wow, a professor that actually works, something is fishy..."

    Certainly. Presumption isn't always a bad thing, as long as you understand what you're doing.

    Look the word up in a dictionary.

    Nonsense. Science is a set of methods, or more broadly, it is commonly thought of as the collection of results from applying those methods. None of that includes God (or gods) in any meaningful way. See your history, particularly Francis Bacon.

    I refer you to Karl Popper, provisionally. Francis Bacon is so 4 centuries ago. Even the philosophy of science changes its schizo mind a too much to be trusted, quite apart from its 'facts'. You might like to also look up the word "nonsense".

    Science and mathematics are the only ones in that "litter" that ever grew up to be more than clueless puppies, actually.

    They are conditional on philosophy. Ie, what is "Truth". Neither mathematics nor science even approach that question. They ask the question : "Is this true/untrue respectively?". Its like the difference between an animal and a human: the animal sees the world, the human sees into the world even though it lives within it, and thinks of what might be outside of the world (even beyond understunding). Beat that with your namby pamby science. Scientists are pansies : they can't handle the Truth!!

    Religion was stillborn with regard to evidence and reality

    So let's say that God reveals himself: let's say he does it by union to the creature. So the creature sees with God's eyes and see's God's reality as if he were God. I've just defined baptism . Even mathematics can't beat that for proof. Science doesn't even believe in proof. Scientists don't beleive in anything, and go on about truth rather too much.

    philosophy spends most of its time chasing its own tail.

    So it does, and so perhaps it should. I refer you to the essays of Chaitin, the God-son of Godel who proved that mathematics is as arbitary as any other subject. In anycase think of this : take a (hypothetical) all-knowing thing: he will know himself, and if he is all that there is then he is self-referential. St Thomas Aquinas defined the Trinity in terms of self-knowledge. Chaitin is obsessed with self-reference.

    Seriously: science really isn't that interesting. Look further. I urge you, even beyonf methemtatics. And if you really believe in truth then question all your assumptions, every single one of them, and don't stop. Christians have to do it all the time. Its tough. Particularly when up against the more knowlegeable and clever.

    Reality is what it is, and no amount of reputation, admiration, or even worship, will change the basic facts of existence.

    The believer in a nutshell! But where's your proof?
