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. "

    It looks like she did this almost 2 years ago. So why is this being announced now?


    Because China now uses anti-satellite weapons now, so we have to "up" the evil-status a bit.

    SHA-1 includes both addition and modulo, which we can no longer consider secure.

    The probability is very small in a random universe, not any one you pick. And it still only implies a finite number of universes. And the correct spelling is "astronomically", which however means extremely large. You probably meant "infinitesimally"

    That is 1 for school masterism, 0 for responding without thinking.

    Speaking as a graduate student already avoiding all teaching duties and enjoying grants that basically asking nothing in return (my country is generous with funding), I think rewarding laziness is a very good thing.

    We know Cthulhu turns into a mist (Call of Cthulhu), we know he can't pass the elder sign and we know that the Chinese can etch entire names onto grains of rice. So, if we hire the entire of China to etch elder signs onto the sand used to make cement, summon Cthulhu into a flooded cavern, run a boat through him, then flood the cavern with the modified cement, you can prevent him reforming and eventually he'll go insane.

    Oh.
