8927147503635671.jpgThe press release has gone out on the official AACS website, but that’s just the final flower on the coffin, and they are a little late in the announcement. DRM on the the two new high def optical disks formats have both officially fallen to the efforts of dedicated hackzorz Muslix64. So, let me back up for a moment, HD DVD and Blu-Ray both use the AACS content protection system. AACS utilizes a 128 bit encryption system, and no, before any starts to correct me, they haven’t done a brute force crack of the protection, the laws of physics are still safely in place. What has happened is that the fatal weakness in both of the schemes is that for anyone to actually watch a movie, the encryption key has to be available to the player so it can decode the movie and play it on screen, and that is the weak link. There isn’t any need to try a brute force attack on the encrypted data if you can just snatch the keys from memory while the disk is playing.

What do the DRM scumbags AACS have to say about it?

AACS LA has confirmed that AACS Title Keys have appeared on public web sites without authorization. Such unauthorized disclosures indicate an attack on one or more players sold by AACS licensees. This development is limited to the compromise of specific implementations, and does not represent an attack on the AACS system itself, nor is it exclusive to any particular format. Instead it illustrates the need for all AACS licensees to follow the Compliance and Robustness Rules set forth in the AACS license agreements to help ensure that product implementations are not compromised. AACS LA employs both technical and legal measures to deal with attacks such as this one, and AACS LA is using all appropriate remedies at its disposal to address the attack.

Hmm, they sound pissed. We are about to see something pretty interesting I think, in that part of the AACS system allows the revoking of keys, which is nice for stopping piracy, but not nice in that it bricks whatever player was used to tease out the encryption keys. Early adopters be warned, MPAA will stop at nothing, including turning your $1000+ movie player into an expensive paperweight, to protect their content.
