Linux Driver ps3encdec

  • I'm using this driver to set/clear my ATA and VFLASH keys.
  • Tested on Linux 3.5.1.

  • 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.
