Decryption Keys For HD-DVD Found, Confirmed

kad77 writes "It appears that, despite skepticism, 'muslix64' was the real deal. Starting from a riddle posted on pastebin.com, members on the doom9 forum identified the Title key for the HD-DVD release 'Serenity.' Volume Unique Keys and Title keys for other discs followed within hours, confirming that software HD-DVD players, like any common program, store important run-time data in memory. Here's a link to decryption utility and sleuthing info in the original doom9 forum thread. The Fair Use crowd has won Round One; now how will the industry respond?"

  6. The response will be the dumping of HDDVD. by Opportunist · · Score: 5, Insightful

    Quite simple. The content industry will simply dump the format, after all, there's an alternative. Now it's high time to show that BluRay is just as "consumer friendly" and break it for good, so there is no alternative left, and if the studios want to get their content to the customer, they have to accept that DRM is useless in their strife to protect their rights.

    The point is to create as much damage as possible, so the industry learns that the only one hurt by DRM are they themselves. Revoked keys mean more work, more expense, more hassle and dissatisfied customers who have to jump the hoops. This will in turn create more awareness for DRM and the problems it creates.

    We have to teach the studios that DRM is a failure. That it only generates hassle and problems for their paying customer and is no barriere or even a deterrent for the pirates. For this, the customer has to be the one hurt, too. Learn the easy or the hard way, learn about DRM by investigating or by having your tools stop working.

    Yes, that's not the usual gentle way of teaching. But appearantly some people don't learn 'fore it starts to hurt.

      Except for the fact that HD-DVD is cheaper for the consumer, and also has the backing of the porn industry since Sony is prohibiting porn on Blu-Ray. So consumers will continue to buy HD-DVD players to watch their porn in HD and Blu-Ray usage will continue to flounder. Sales of mainstream titles on Blu-Ray will do poorly and the movie studios won't make any money. They'll either have to offer titles on HD-DVD or give up on HD sales altogether. On top of that, it's only a matter of time before Blu-Ray protection is cracked as well. IIRC, the Blu-Ray encryption is similar to HD-DVE encryption, so it shouldn't be all that difficult.

  7. Again, this is NOT a crack! by KonoWatakushi · · Score: 5, Insightful

    New disks can be pressed with new keys, and the compromised software player will have it's key revoked. As such, this is not a generally useful solution. AACS remains secure, and at best, we may see individual keys available for certain pressings of certain discs. This approach will never provide general playback as DeCSS does.

    However, it is my understanding that the decryption process can be done by the TPM; once this is supported, the problem will be much more difficult. Make no mistake, the battle has only just begun. Before long, software based attacks may be rendered impossible.

      You're forgetting one, key principle here.

      Only one person needs to "crack" the encryption once.

      It doesn't matter, at all, that they (the "big evil guys") can revoke keys. Get one key, decrypt it, and you now have DRM free audio and video. It only takes one to fire up that BitTorrent client. Who cares if the key is revoked after that? Once you have the data, you have the data, plain and simple. All it takes is once to seed a torrent.

      Put it that way, and you can tell it's not about stopping pirates. It is about stopping free usage of a media you have legally purchased through other methods, which it does perfectly.

      Pirates just give them a "pubically acceptable" reason to DRM your house, down to the nails that hold it together.


      You do have a good point about the TPM, though. However, seeing as nothing that I know of to date uses it, well, I for one am going to wait and see just what happens with it. It has a lot of potential, for good, and for bad...

    You are correct, sir. The attack vector is the same, keys being exposed in insecure memory in the decoder/player. The encryption of AACS itself is unlikely to be cracked as it's AES, and AES is very nifty and well studied. Even if the key searching approach fails, there *are* possibilities that some sort of attacks could be waged on the AES implementation which might be vulnerable. (For instance, I wrote AES for MATLAB. It's highly likely that my implementation could be exploited for various reasons, such as cache timing attacks.)

    Even if they one day develop a perfect DRM scheme full of unbreakable secure paths, it won't be possible to avoid someone simply removing the actual LCD screen, wiring the signals instructing which pixels should turn on and off to a 3rd party device, and recording the unencrypted content in raw format.

  12. Who cares about existing titles? by Overzeetop · · Score: 3, Insightful

    Everyone seems to be missing the point. Existing titles are chump change. Just make the next pressing with the new key. The flurry seems to center around release dates anyway, so no future discs will decode on the compromised player. They don't want to make it impossible, they simply want to make it difficult. Having to keep a key database updated is a pain in the ass. I'd go as far as to say that they don't care about an isolated crack - they'll "fix" it and go on, with updates from time to time. This is a s/w player, not a hardware player, correct? Just require an update.

    The point is that they will make this about Piracy, and that its the Pirate's fault that you have to go download an update to get your machine to work. Not their fault (Say "Not my fault" in David Spade's voice an you'll get the idea). Most consumers will believe the newsvertisement they see on ther local station that blames those evil pirates for their suffering. If it weren't for the pirates, their stuff would work. Which can easily be spun at truth - pirates cracked the system, system must be safe or poor artists children will starve, so we had to change the system - all pirates fault. Your mother would fall for that, and you know it.

    Right and wrong is irrelevant - it's who takes the blame for the mess that matters, and the industry has a lot of PR money to make sure the finger points at someone else.

      Yeah, right. Take a look at the prices for DVD seasons of for example Babylon 5 or Star Trek... they're incredibly expensive even though they're many years old. How much does Disney classics go for again? Besides, it's probably not like pirates are going to announce their player keys, they'll likely just release the titles.

      The sad thing is that it'll work for release groups having decryption keys and pirates getting decrypted versions, while it probably won't work for average consumers who wants to do fair use like back-ups, format shift, non-HDCP screens and so on, because they don't have a disc from the same batch.

    I'll say your nom de plume is appropriate. There are two ways to reconcile these positions logically. One is that it is not the same Slashdotters making both claims (we have diversity of opinion here, in case you failed to notice). The other way is that the "competition" the first claim refers to is between corporations, not between formats. The former fuels markets, the latter fragments them. It's true that the latter is a consequence of the former, but it is not an inevitable consequence. For instance, nearly all books published in English today have the binding on the left side, even though there are many publishers competing for your cash.

    "What is needed is a DRM that is advanced enough to be flexible enough to allow all "fair use" while curtailing piracy."

    DRM will never be this advanced, because this proposal is fundamentally impossible, because it implies logically inconsistent outcomes. Either I can copy no part of the video for any reason, or I can copy some part of the video (no matter how small) for any reason. If I can copy any part, even screenshot by screenshot, for any reason, I can re-assemble it outside the player and the DRM is therefore useless. If I can't, fair use is violated.

    DRM, in all it's manifold and perverted forms, can go to hell.
