HD DVD's AACS Protection Bypassed

Posted by kdawson on from the 8-days-to-a-crack dept.

Mr. BS writes "Playfuls.com is running a story how HD DVD's AACS protection has been compromised. Although the video of the hack leaves much to be desired, the source code has already been made available. Feel free to start backing up your HD DVD's whenever you feel the need."

    Half-dupe. The last story said source coming in January. This one provides source.

    That article is wrong is one regard: "CSS relied on a single set of keys that were used to encrypt every DVD and were provided to every DVD player, both hardware and software."

    CSS also uses different player keys. The three big differences between AACS and CSS is that AACS has many more player keys (CSS only had ~400), once one player key was discovered, you could easily discover all of the other player keys, and weaknesses in the encryption algorithm made it possible to discover the title keys without any player keys.

    As the video said, the real story isn't the software released (it merely implements publicly-available standards), but that title keys could be obtained from PowerDVD.

    You should pay more attention before you "correct" other people...

    The source was linked in the Doom9 thread the /. story linked to. I have the zipfile on my hard drive to prove it, and a large number of the comments in that thread revolve around a review of the source.
