First Blu-Ray/HD-DVD key revoked

And the saga continues. The content protection system used on next generation HD capable DVD's (AACS) was recently compromised through an exploit in the popular WinDVD software made by Intervideo. In a departure from the standard definition DVD encryption spec (CSS), AACS allows for the publishers to revoke keys handed out to specific licensees, if those licensees somehow misbehave or compromise the system.

Due to the revocation, WinDVD users must upgrade to a new version -- containing a new key -- if they want to watch the HD-DVD's they own.

DeCSS rendered useless the entire CSS system on first gen DVD's, making copying, ripping and backups a trivial procedure. So far, the AACS equivalent remains elusive. However, you can bet that someone somewhere is hard at work on a way to compromise AACS again, either in a short term single key crack -- like the one we've seen here -- or a longer term, system wide crack. There isn't a single known DRM system worth cracking that hasn't been cracked, multiple times; AACS will likely be no different.
