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."

  1. What will the packaging say? by The+New+Andy · · Score: 5, Interesting
    Suppose player X has been revoked. Now, I'm assuming that any disks released after this won't work on it right? So, does the packaging for the disk say: "Plays on any player except blah"?

    Now, how does this scale, suppose players AAA through ZZZ have been revoked. Do we need larger DVD cases just so we can fit a list of all the players that won't work on it?

  2. This isn't new news... by harmless_mammal · · Score: 5, Interesting

    Here's analysis of AACS that was blogged last December. One interesting point mentioned is that there is no requirement to wait for keys to get compromized before revocation begins. They can revoke keys whenever they want, publicly claim it was due to hackers, and stimulate new equipment sales any time they want.
