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?"
``The Fair Use crowd has won Round One; now how will the industry respond?''
I think at least the Blu-Ray camp will switch on their intergalactic megaphones and tout how Blu-Ray was superior all along. This whole format war is childish enough for that.
Please correct me if I got my facts wrong.
Who needs Blu-Ray anyway?
That format has killed itself by Sony's arrogant attitude. History has shown that locked-in, porn-shy formats always loose.
HDCP is the biggest crime in consumer history yet, let's hope this development kills it before it really takes of. For me there are two choices:
1) HD content works with my current and future hardware setup
2) No HD content for me
It's about time those media companies learn what they are producing their precious content for.
It will send in a few lawyers. After a while, they will realise that their impact is negligible in the grand scheme of things: the DRM will continue to deter casual copying to some extent, but will continue to be impotent in preventing anyone determined to make a copy and willing to spend a little time on the 'net to find out how (or download a pre-ripped version).
Meanwhile, genuine customers will get seriously annoyed at the fact that DRM in HD-world has now moved beyond a minor inconvenience or ethical question as it was with things like DVDs, and into the realms of seriously impeding their enjoyment of the product they have legally purchased. A consumer backlash will result, with the effect that DRM becomes a "dirty word" 2-3 years from now, and distributors drop heavily-encumbered formats and go back to what works: a mostly hands-off scheme that's enough to deter casual copying by schoolkids but nothing that risks seriously impacting the marketability of their merchandise.
On the same sort of time scales, on-line distribution will reach a critical mass, and the movie distributors will adopt a second, parallel strategy where cheap, legal, unencumbered downloads are the norm. They will make their profit from on-line users through many small incomes, rather than the larger one-offs represented by (HD-)DVD purchases today. This will render illegal distribution channels mostly irrelevant, and the damage due to illegal copying will revert to being low-level noise as it mostly was before they started their current crusade anyway.
Hey, it's a new year and everyone else is making crystal ball predictions. Can't I have mine, too? :-)
If you disagree, post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like.

Every time I read a rant about HDCP, I conclude that customers (and content providers as well) have not the slightest clue what HDCP does.
At some point, after all the decryption, decoding, filtering and whatever else is done, your computer must send a signal to the monitor, which the monitor then translates into an image that you can see. This signal usually comes out of the DVI connector in your computer, goes into a cable, which feeds into the monitor or TV. Our paranoid friends at the MPAA or whatever abbreviation it is are afraid that you could catch the signal coming out of the video card, and record it.
Truth is, you can't. You just can't record a signal of 1920 x 1080 pixel times 12 bit per pixel times 60 frames per second on a harddisk. Well, I can't and no normal consumer can. There are people who could build stuff that could do it, but those people are probably happily building graphics cards for NVidia and ATI, or building DVD players.
Still, that signal had to be encrypted. So you have a chip just before the DVI chip (or integrated into it), and another chip in your TV, and they can negotiate to decide on a key for a cipher stream, and use that cipher stream to encrypt the signal on one end and decrypt it on the other end. Which means you can't record the signal coming out of your computer and turn it into a DVD. However, this has nothing to do with DRM whatsoever. Once this encryption is turned on, it stays turned on until the computer or the monitor are turned off. So if you read slashdot after watching a DVD, everything you see on the screen has gone through encryption and decryption. Doesn't matter, because you couldn't read the signal from the cable anyway.
Where the real effort is: First, the graphics driver has to check constantly that encryption works properly. That is not to make sure you don't steal the video signal (as long as encryption is turned on, you can't, and encryption doesn't turn itself off), it is because if the video card and monitor run out of sync then you will see nothing but snow on the monitor, and that makes for a very very unhappy customer. Second, all the commands from the OS to the driver are encrypted, and status reported by the driver is encrypted as well. Otherwise, a hacker could just pretend to be the OS and tell the graphics card to turn encryption off - and that's it! No, most of the work is not the encryption, but to make sure that the OS always knows whether encryption is turned on or off. And third, a DVD can request that high resolution is only used with encryption, so if the HDCP chip isn't there, the image is scaled down to lower resolution.
All in all, the whole HDCP stuff is complete nonsense. It prevents an attack from thieves in a place where you wouldn't attack. It costs money to add and implement. It doesn't hurt you as a consumer, except that you have to pay for the damned chips. It creates work for device driver writers. It doesn't protect contents. Anyone who can record 200 MB per second from a DVI output has invested some serious money, and a little bit more money will allow you to break into a monitor and get the signal from there.
Executive summary: If you can't record a signal coming from the DVI cable, HDCP doesn't matter. If you can record a signal coming from the DVI cable, HDCP doesn't matter much either.
Has the same thing been done for Blu-Ray yet? I would like to see DRM on both systems being shown as being useless.
:-) Makes me wonder if it's possible they'll do this with HD-DVD, or if it has reached critical mass alraedy, so to speak.
I agree, although it would be more amusing to me if Blu-ray DRM was broken with various key extraction algorithms in about 6 months or so, for it to reach the market better and give them less hope to just change details in the standard as a worst case scenario.
Beware: In C++, your friends can see your privates!
your premise about needing to record 200MB/s is incorrect because it doesn't need to be played back at 60fps in order to make a copy! set your player to play at, say, 1/10th speed and suddenly you only have to record 20MB/s. sure, the RIP process takes 10x as long but, really, big deal.
They could take a more drastic approach, and simply revoke the keys to all software players, since software players are too easy to extract keys from. The already cracked discs would still be available for piracy, but further discs wouldn't be playable on anything but hardware. That would definitely suck, and would render the "victory" as Pyrrhic.

Unfortunately, dismissing the porn industry is what killed the technically superior Betamax. Without it, all they have is the rabid PS3 fans to bolster their film sales - and that's only if the gamers want to take a minute to watch a movie.
