198w ago - A few weeks back GeoHot Hacked PS3, and now a new patent has surfaced from Kanna Shimizu of IBM for a method to protect secrets against encrypted section attacks.

Take a look here, to quote: "A method, system, and computer-usable medium are disclosed for controlling unauthorized access to encrypted application program code. Predetermined program code is encrypted with a first key.
The hash value of an application verification certificate associated with a second key is calculated by performing a one-way hash function. Binding operations are then performed with the first key and the calculated hash value to generate a third key, which is a binding key.
The binding key is encrypted with a fourth key to generate an encrypted binding key, which is then embedded in the application. The application is digitally signed with a fifth key to generate an encrypted and signed program code image.
To decrypt the encrypted program code, the application verification key certificate is verified and in turn is used to verify the authenticity of the encrypted and signed program code image. The encrypted binding key is then decrypted with a sixth key to extract the binding key.
The hash value of the application verification certificate associated with the second key is then calculated and used with the extracted binding key to extract the first key. The extracted first key is then used to decrypt the encrypted application code."

Tavenui, you're the man I completely agree with you. People want to see this cracked for different reasons, some of which have more than one. I too don't see the point of limiting a console capable of so much more, other than that it's just good business. Think about the possibilities of a fully unlocked and unlimited PS3 Farm.
Yes, farms exist now, but the PS3s on those farms are still limited. I honestly don't really know what exactly could be accomplished with an unlimited capability farm, so if someone would please comment it would be much appreciated. Besides, all the needed reason should be "Free as in Freedom."
We have to respect the business model put forth by Sony, but we should still be allowed the freedom in respect to that. I guess it never goes hand in hand though?
A random thought occurs to me, I don't think it has anything to do with the scene, as in "OMG THEY'RE CRACKING IT", rather I can see it being used more for those nice PS3 farms the Air Force has. Those are things I can see needing more hardcore protection.
