HDCP Encryption Cracked, Details Unreleased Due To DMCA
Lord_Pall writes: "There's a very good article on SecurityFocus about a Dutch cryptographer. He apparently has cracked the HDCP video encryption standard, but won't release the research for fear of reprisals under the DMCA."
Update: 08/15 06:10 PM by J : Meanwhile, see
Keith Irwin's paper
which has been released despite the DMCA.

And someone else points out
this old thing.
Everyone who hasn't written a paper on cracking HDCP raise your hand.
ROT-13???
Hell, publish it as an Adobe E-book
Me too, and here's where you can get it:4 f1 6ad2ec7296a7a9fb3.dat

It's encrypted. It's also copyrighted. If you decrypt it, you bring down the wrath of the DMCA on yourself. So don't decrypt it.

Don't piss off The Angry Economist
Intel spokesperson Daven Oswalt says the company has received several reports from people claiming that they have broken HDCP. But he says none have held up, and the company remains confident in the strength of the system.
Oswalt went on to say, "If anyone DOES substantiate their claims, we'll sue the pants off 'em."
In other news, Intel will be holding a decryption contest. The winner will be presented with a fine of up to $150,000!

I've uncovered the secret ingredients in the Colonel's spices and McDonald's Special Sauce. I figured out where Amelia Earhart has been all these years. I know whether or not the moon landings were faked, who shot Kennedy, and how many stones there are in the Washington Monument.
I have decrypted the secret code in the Bible, correlated it with the secret codes of the Baghavad Ghita, Talmud and Qur'an and now now the inner thoughts of all gods. I have unified field theory and quantum theory and will soon have a device that will bend all matter to my will.
I know the secrets of teleportation, telekinesis, telepathy, and how to get women to want me. I know the secrets of every three-letter agency in government, the Psychic Friends network, and the US Postal Service.
Unfortunately, due to the nature of the DMCA, I am unable to share my findings with others. I suppose I'll have to get on my FTL spaceship and find a more genial planet. Ta-ta!
You people are overlooking the upside of all this.
Now we can FUD any copy restriction technology top death by claiming that we broke it, and refusing to give any details due to the threat of prosecution under DMCA!
The question is, would this be effective enough to get the media companies to stop using it?
Indeed. I'll bet those Germans who invented Enigma are kicking themselves (posthumously, natch) that they didn't legislate against the Allies cracking it : )
This is a Good Thing(tm)! If the details aren't released, then it's just rumor, speculation and slander against the HDCP standard!
That means the HDCP consortium can continue on their merry way to rolling out their video solution...and then after we have all this great content available...THEN we can have someone release the information (I see Lawrence Lessig waving his hand there in the back).
Think about it. If the Crack SDMI has come back with nothing but failure...then maybe we would all have GB of juicy full-quality (minus watermarks, ahem) songs sitting on our harddrive awaiting a simple watermark snipper.
Thank you DMCA! Chilling research only delays the inevitable! It doesn't stop it!

...For this I have found a truly wonderful proof, but the DMCA prevents me from publishing it.
If he wrote the paper, then I would assume that he owns the copyright on it. If he's a cryptographer, then he can apply an encryption algorithm to it. If he does that, then nobody can read it w/out breaking the encryption, and, therefore, violating the dmca...correct? Granted, we'd all have to violate the dmca to read it, but how is Intel going to see you ROT-13 something in your cubicle?
Juiced? Or Not?
"An experienced IT person could recover the master key in two weeks given four standard PCs and fifty HDCP displays"

Therefore the key is:
12450 or
114450 or
12450 * 114450 = 1424902500 or
sqrt(12450^114450).
q.e.d.
keep it simple.
Of course not. What, do you think some company is going to file charges and get the FBI to arrest someone from Russia just because they give a talk about their work in Vegas? Or that an industry trade group would threaten a lawsuit if a college professor tried to present a research paper? My god, people are paranoid around here! Next thing you know they'll be saying that the Big Corporations are trying to outlaw reverse engineering!
