BackupHDDVD 1.0 Released

Muslix has released his tool to allow you to copy HDDVD movies, it is called BackupHDDVD, he didn’t actually crack the DRM, like I said here, but, because the players are insecure, he can extract the keys to allow him to copy the movies using his program.

The attack I describe in “Affirmation 4″, is not here yet, but its coming. So I give MPAA and AACSLA a head start. Start to think what you can do about that.

To totally block this attack, they need to put different keys on every disk! Now, they only have different keys for different movies. I don’t know about the manufacturing process of the disk. This solution may not be possible.

The best they can do, is doing shorter manufacturing run of a particular movie, so it would be difficult to get your hand on every “pressing” of a movie.

When they design AACS, they assume people will look for the device keys. I don’t care about device keys. I do care about volume key. Having the device keys mean that you have to re-implements all the complex crypto and do the full AACS process.
I leave all this dirty job to the player and recover only the volume key.

There is 3 important things in cryptography:

1-Private key protection
2-Private key protection
3-Private key protection

Did I break AACS? I don’t know. What do you think? Source: BackupHDDVD, a tool to decrypt AACS protected movies
