It's just precedent. The decryption algorythm has to be in the firmware. Spy the bus, and rip the decryption key. I bet there will be libbluraydcrypt and libhddvdcrypt shortly after firmware releases in players.
Oh here we go again. How much do you wanna bet, Beer?
Or when you say "I bet," does it really mean, "I hope?"
Do you know
anything about AACS? At all?
CSS was a symmetric (one-key) system.
AACS -- which is what you'll see on HD-DVD and BluRay -- is
asymmetric. Multiple keys.
First, "They" don't hand out device keys to just anyone.
Second, if you make HD DVD players, and you do get device keys, and you let them escape, the licensing agreement allows Them to extract enough fines from you to put you out of business. Please pay $10 million dollars and go directly to jail, do not pass Go, do not collect $200.
Third, then what They do is add the compromised device keys to a
key revocation list on all
future HD discs. So guess what? Those keys that escaped? They don't work with anything that is released AFTER the compromise. The device key revocation scheme is ingenious -- they can revoke an entire manufacturer (e.g. all Samsung players), or a specific model of player, or even a single specific player if you piss Them off. LOL
I'm just scratching the surface here. They've got stuff in there to prevent bit-for-bit copies. You can't just "spy the bus" because the bus traffic itself is encrypted.
I haven't even
mentioned HDCP yet.
Or BD+, which allows them to swap in A WHOLE NEW ENCRYPTION SCHEME at will.
"DVD Jon" is not going to sit down with a can of Yoohoo one weekend and crack this nut for you. It's just not going to happen.
Ironic that you mentioned "videolan" libraries being used. If you go over to the VideoLAN site, they are screaming that
the French Government is threatening to make those libraries illegal:
http://www.videolan.org/eucd.htmlNow if the EU is going to crack down on
DVDs in Linux -- where the cat is already out of the bag, if you will -- what do you think they're going to do about HD-DVD and Blu-Ray?
What They're implementing isn't perfect. No doubt, one day some device keys will go missing, a Chinese HD DVD player manufacturer will suddenly go bankrupt, and the Linux weenies will claim that AACS has been cracked. Then the next morning, someone in Hollywood will get up, a push a button and every single HD disc that comes out
after that won't play on the "cracked" systems.
Were you serious about betting, or were you just talking out of your a-- again?
