Sony’s Answer to Geohot’s PS3 hack
Sony Releases Anti Geohot Patent.
anti-ps3-hack
Sony have recently registered a Patent that could render the likes of exploits like Geohot’s recently released PS3 hack useless. The technology was developed by a Sony employee by the name of Kanna Shimizu, who is a security Architect for cell Based Security Achchitectures.
We here at Modsandhacks think that this is a direct stab to to Mr Geohot. Sony are obviously trying to make a statement by trying to stay one step ahead.
Here is Qoute from the Abstract of the Patent
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.
