Your posts demonstrate a high level of knowledge, so I'm reluctant to disagree, but the AACS LA has the ability to generate a new MKB that revokes some device keys, but not others, and they can generate new device keys that will work with new and old MKBs. No one here can do any of this. The AACS LA has secret keys that are used to perform those functions. If people here had the key(s) they have locked in their vaults, they could generate device keys, new MKBs, etc. and the system would be forever broken.

That's why no one here can say that the AES/AACS system has been cracked - it's only been bypassed. Getting the secret keys stored in the AACS LA vault will be very very very hard. Cryptographically, the AES/AACS system is very very good and not likely to be broken soon.

It was bypassed because the whole concept of encrypting something that you have to let the recipient decrypt is a fundamentally flawed concept. They have to give out the keys to millions of people so they can watch the encrypted movies - how can they expect to keep them secret? The only thing they can keep secret is how to make the keys they give out.
