AACS Specifications Released

Posted by ryuzaki0 on from the meet-the-new-css dept.

An anonymous reader writes "AACS, the proposed key management scheme for HD DVD, has finally released preliminary (ver 0.9) specifications. The specs look like CSS on steroids: they use AES instead of proprietary crypto, but other than that they're basically the same. The main difference appears to be that AACS can revoke an entire player model if a hack appears against it, which I guess sucks if you own that kind of player."

    This scheme will not be broken for at least 20 years.

    There's no way they'll make the same mistake twice. DirecTV upgraded all their smart cards 2 or 3 years ago and it has yet to be broken. Bell Canada's expressvu is adopting the same technology because _everybody_ and their mom is pirating the signals.

      If they *really* want an unbreakable scheme, let them encrypt all HDDVD's using one-time pad encryption, then securely delete the key.

      If they do it right, pirate copies will be truly impossible. Granted, no one will be able to play the legit copies either, but it's my impression that this is only a minor concern to the companies involved.

    I must admit that I thought an encryption standard based on the Cascading Style Sheet specs was a clever idea. Should be almost impossible to decipher.

    They start the healing process by investing the money they would have spent on new players in some of the fine products made by Barrett Firearms Manufacturing, Inc., and the information provided by fine financial periodicals such as the Wall Street Journal.

  6. So they are using AES? by pesc · · Score: 4, Funny

    Here is why using a stronger crypto or longer keys is not always the answer. The design of the system around it matters too.
