This is “Not” the key to my Wireless Network. However it is the HD-DVD processing key that is used for most HD and Blue Ray movies released so far. Now for those of you not in the know, here are some terms that you need to know.

For more information on these terms check Wikipedia.

AACS is an integrated set of technological protection measures that controls access to and prevents unauthorized copying of copyrighted motion pictures embodied on high definition DVDs.

What this means is that this is the Hex Key needed in software used to decrypt and watch HD-DVD movies. Both HD-DVD and Blue Ray media use AACS DRM to protect there content. Of course due to the revocation procedures introduced in HD-DVD’s encryption scheme this key will not be good for long. However the procedure for getting the key has already been figured out by an anonymous programmer called Muslix64 and is implemented in a program he wrote called BackupHDDVD.

However if that were not bad enough, there is now a new hack. This one is a hardware based AACS attack, that uses the Xbox 360 HD-DVD drives and that hack cannot be revoked. It is accomplished by de-soldering the HD DVD drive’s firmware chip, reading its contents, and then patching it.

If all this sounds familiar, it’s because the standard DVD decryption in use today was cracked by three people, two of which remain anonymous, however the third in this trio was a Norwegian named Jon Lech Johansen whose home was raided by the police and he was placed on trial for violating the DMCA. He was acquitted of all charges in early 2003. Others were prosecuted just for posting or linking to the DeCSS source code. I think this just goes to show that nothing is ever really secure.
