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.
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."

to tell the true.... I'm interesting in iso loader.... I'll say a lay if I say not but... I have to say that for me is now more important have the video card (RSX) unlocked under linux. if sony will do it by her own (very difficoult but never say never) I'll be very happy too..
I have 2 PS3 60 gb , and I'm very happy to have them, this 2 machine have linux installed (ubuntu 9.10,yellow dog 6.2) and do their job very well but with the RSX for sure I can start to dream.
these fews of words are for say that game for PS3 for me are not so important cause PS3 offer many other things maybe most important, this FOR ME is the reason why Sony not provide in linux support of video card in the PS3 phat and in the PS3 Slim remove totally otheros.
