You can only encrypt the harddisk, not the RAM. When using FDE the RAM is always unencrypted by design, no way. If you encrypt something in RAM you can not see it. :) Usually you have to hide more then just 1 MB. It might be a good idea for vendors from encryption software like you say to up the masterkey in RAM in an area where it will get overwritten by BIOS... But there is still enough other interesting content in RAM, not encrypted and not wiped. > > Unless of course... > > - somebody takes the chips out and has an adapter > where he can read them without any BIOS messing > > - somebody forgets to disable FireWire, then I can > fetch the RAM contents without cooperation of the > operating system because all devices have DMA host > access ;-) > > Eric > > > > > ------------------------------------------------------------------------------ > Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) > software.
