I understand what cold boot attack is although what is this suppose to
protect against exactly? Is it dismount encrypted drive and wipe after x
seconds of inactivity? If the system loses power wouldn't the attack still
work since you couldn't have wiped it? Or is it that through the use of
registers you are avoiding storing it in memory and are wiping that memory
which is initially used? The question then I would think becomes can you
recover from the key from the registers.
