Introduction
- The following information was reverse engineered from LV1, Storage Manager in LPAR1, sb_iso_spu_module.self and sv_iso_spu_module.self.
Linux Driver ps3encdec
- I'm using this driver to set/clear my ATA and VFLASH keys.
- Tested on Linux 3.5.1.
Establish Secure Communication Channel
- First host and ENCDEC device exchange random numbers.
- From the exchanged random numbers host and ENCDEC device compute the session key.
- ENCDEC commands, e.g. to set ATA keys, are encrypted with the session key.
