AACS Specifications Released

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."

I accept?

No Thanks. I'll just wait for it to get posted to /.

Mark my words.

This scheme will not be broken for at least 20 years.

There's no way they'll make the same mistake twice. DirecTV upgraded all their smart cards 2 or 3 years ago and it has yet to be broken. Bell Canada's expressvu is adopting the same technology because _everybody_ and their mom is pirating the signals.

Just press the "easy button".

If they *really* want an unbreakable scheme, let them encrypt all HDDVD's using one-time pad encryption, then securely delete the key.

If they do it right, pirate copies will be truly impossible. Granted, no one will be able to play the legit copies either, but it's my impression that this is only a minor concern to the companies involved.

Okay, DVD Jon...

You have your work cut out for you!

Just kidding. :)

THis new standard will probably require 15 lines

Well then...

I must admit that I thought an encryption standard based on the Cascading Style Sheet specs was a clever idea. Should be almost impossible to decipher.

They start the healing process by investing the money they would have spent on new players in some of the fine products made by Barrett Firearms Manufacturing, Inc., and the information provided by fine financial periodicals such as the Wall Street Journal.

better crack the PS3 first ;-)

[cheekyboy]

to piss of sony, after all they are part of the consortium , ahhaahahahha

So they are using AES?

[pesc]

Here is why using a stronger crypto or longer keys is not always the answer. The design of the system around it matters too.

I was thinking organized crime in a different way:

1. Sony hacks and releases the codes for their competitors
2. ???
3. Profit!

'Sir, people keep pirating our movis!'

'Quick! Find some honest customers and kick them in the balls by breaking their DVD player!'

I.e., the beatings will continue until morale improves.

What's that rule again? Any organization's behavior can be predicted if it is assumed to be controlled by a secret cabal of its enemies out to discredit it?

Why hack the decryption keys?

[Xoder]

I think hacking the revocation keys could be more interesting.

A: Dude, I got this great new movie, wanna see it?
B: Yeah!
[A puts in an HD-DVD-R with all major revoke keys on it]
A: Oh shit, its not working man.
[A enjoys the little prank he played on B who will never be able to watch a movie again on his player...]
