HD-DVD AACS DRM Cracked?
Posted by XanTium | December 27 22:32 EST

 
From engadget.com:


Can it be? Is Hollywood's new DRM posterchild AACS (Advanced Access Content System, see more here) actually quite breakable? According to a post on our favoritest of forums (Doom9) by DRM hacker du jour muslix64, his new BackupHDDVD tool decrypts and dismantles AACS on a Windows PC. Just feed the small utility a crypto key [none released with application, more about it in FAQ], and it'll dump the video right off the disc onto your hard drive, supposedly playable in any HD DVD compatible player. If true, this would instantly become the DeCSS of high def optical, as AACS is the copy protection scheme used not only by HD DVD, but by Blu-ray as well.

You can read the FAQ released with the application here

Wow. Blu Ray also uses AACS. Not a good day for High Def content providers.

It's cheaper than a 'real' PC HD-DVD drive.
At least for now.

Thats awesome!

Cop Protection is a facade in todays world, I dont know why the industry just embrace it and work with the communities on making a BETTER PRODUCT for everybody..

We as consumers are just too damn smart these days

If I understand what you're asking correctly, you're saying whats the big deal about him using the Xbox360 HD-DVD to do it? If so, it's not really a big deal I just thought it fit nicely considering this is a Xbox forum.

Been playing with this for the last few hours (albeit, without my HD DVD stuff, which is back in colorado).. but it looks like you still need a way to get the title key for each movie you want to decrypt (which he most likely got from doing a memory dump of power DVD's memory space while playing an HD DVD movie) in order to make this work.... He is claiming to work on a volume key version however, which would only need one key to decrypt all AACS encrypted HD DVDs.

My understanding of AACS is that old cracked keys can be disabled at the player level via firmware:
QUOTE
"The approach of AACS provisions each individual player with a unique set of decryption keys which are used in a broadcast encryption scheme. This approach allows licensors to "revoke" individual players, or more specifically, the decryption keys associated with the player. Thus, if a given player's keys are compromised by an attacker, the AACS licensing authority can simply revoke those keys in future content, making the keys/player useless for decrypting new titles."
