AACS encryption cracked, almost
A hacker posted the source code and a video of new software called BackupHDDVD that he developed that ‘supposedly’ allows people to backup HD-DVD.
What really happened is that the method that Cyberlink uses to decrypt AACS was semi-compromised. Apparently this method won’t work for long because the key that is used to decrypt the content can be revoked with AACS. This was something that was not possible with CSS encryption.
