DailyTech – All Blu-ray Disc and HD DVD Encryption Defeated by Single Key — So this guy found a skeleton key? Amazing tale.

What arnezami found was the Processing Key, which appears to be the silver bullet in decrypting all existing HD DVD and Blu-ray Discs. Arnezami was armed only with an Xbox 360 HD DVD player and the bundled King Kong movie. Other Doom9 forum contributors posted their keys to HD DVD movies such as The Departed and Spy Game, which were proved decryptable using the Processing Key.

    HAHAHAHAHAHA! That didn’t take long at all. Is there really any way to make any of these schemes secure so Long as they need a 3rd key?

  2. Wayne Bradney says:

    There’s no way to make any DRM scheme secure as long as the decryption keys have to be sent with the content, which of course has to be the case if you expect your customer to be able to view the content.

  3. JT says:

    Since the encryption scheme is already locked into to existing players and content, hopefully it’s too late for them to go back and lock out this crack. This is the real battle between good and evil.

    John Stewart asked Bill Gates, what does the F12 key do?

    Now we know.

    But, I thought that was the point of the new system….

    Instead of just one key – like CSS on DVDs – the system on HD discs had a large, tree-structure of keys.

    If one key was compromised, they could place updates on new releases – and updated releases of existing titles – which, when played in your player, would update the firmware in your player to revoke the compromised key.

    They can’t keep people from finding the keys, but they can keep sending out updates to invalidate compromised keys.

    They know they can’t prevent hacking, but they can make it such a fluid, “moving target” kind of endeavor that most lazy consumers won’t bother trying to keep-up with the updates. 🙂

    #5 – Wow, that one went right over my head. What bearing does F12 have on DRM? Maybe I just need another cup of coffee…

  7. Andy says:

    Haha, i doubt they’re too happy about that. Bound to happen sooner or later.. bet they weren’t expecting it this quick!

  8. Mark Derail says:

    #6, jokes aren’t as funny once explained…I don’t know where to begin…
    There’s a deeper meaning in there.

    It’s not DRM or F12 the key word…

    I’m in stitches…

  9. James Hill says:

    Seems too easy… like they wanted it broken.

  10. Kenneth says:

    #6. The key tree system (I believe) is just for the hardware. If one of the player’s keys are compromised, it gets revoked. Unfortunately the keys that they are extracting are from the discs. Every single copy of a movie will have the same key on it. Otherwise they’d have to custom press each disc. You get that key, and if they revoke it, they just junked EVERY SINGLE copy of King Kong in the world. But by then it doesn’t matter because the content has already gotten out.
