IBM Anti-Geohack Patent to Protect Secrets Against Attacks?!

239w ago - A few weeks back GeoHot Hacked PS3, and now a new [Register or Login to view links] has surfaced from Kanna Shimizu of IBM for a method to protect secrets against encrypted section attacks.

SKFU writes: It seems it is SONY's answer for GeoHot's progress.

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."

This could be good or bad news.

Either she already knew this would come and hid this patent untill just now.

OR shes cashing in and made a new patent that can be used in future consoles.

Lol really is Sony & IBM really scared that the hypervisor will be hacked in no time? This is a sad move from the corporate side, this patent will not mean anything if system is going to be hacked, no way to trace the author, hackers are not stupid.

Decrypt the keys through some sort of "Folding@Home" app

Just have to write it though and have a few hundred/thousand ps3 owners join in the battle.

Maybe well get those keys by 2052

So does this mean that if you upgrade firmware, you will not be able to dump the Hypervisor? or does this also require a hardware change??
