39w ago - Following up on the previous work by PlayStation 3 developer Graf Chokolo, today naehrwert has announced news of a PS3 HDD decryption proof-of-concept (PoC) from a PC as a result of reverse-engineering work done by flat_z and glevand.

Below are the details (via ps3devwiki.com/wiki/HDD_Encryption), to quote:

Introduction

• The following information was reverse engineered from LV1, Storage Manager in LPAR1 and sb_iso_spu_module.self.
  
• I'm able to decrypt/encrypt my PS3 HDD and VFLASH on PC now.
  

HDD Encryption

• XTS-AES-128 is used to encrypt all data on PS3 HDD.
  
• XTS is NOT CBC!!! It's AES-ECB with tweak XORing. AES-CBC is impractical for HDD encryption. Each sector can be encrypted/decrypted independantly from other HDD sectors.
  
• Good paper about XTS-AES: ntnu.diva-portal.org/smash/get/diva2:347753/FULLTEXT01
  
• VFLASH is encrypted twice. First with ENCDEC keys and then with...

113w ago - This weekend PlayStation 3 hacker Graf Chokolo has disabled the PS3 internal HDD encryption, opening the door to possibilities such as dual-boot PS3 Firmware and using the decrypted PS3 HDD in another console.

To quote: Even without having a PS3 to work with, graf_chokolo is really active in distributing updates and fixes to his PS3 Linux gits. The latest one comes with an interesting update as you can see from his post below. Maybe one step further to a dual boot PS3 FW?

Guys, take a look at "ps3dm_sm set_del_def_encdec_key" command. You can disable/enable virtual FLASH/internal HDD encryption with that And by patching HV process 9 (which sets ATA keys before loading GameOS) you can disable it permanently. It means you could swap your internal HDD and use it on another PS3. But you have to restore the content on it after disabling encryption because all data will be encrypted of course.

Soon i will implement ENCDEC device driver for PS3 Linux and you will be able to experiment with ATA encryption. ENCDEC device is responsible...
