Hi, sorry for the late reply... but I've been wondering if these attacks
- rebooting the device into some kind of imaging tool for retrieving the
memory image with the encryption key - can't be prevented by storing
the key in a place in memory where it would be inevitably overwritten by
the contents of the boot media.
Obviously this wouldn't stop the kind of attacks where the cooled RAM is
being read in some kind of external device, but it would surely make
attacks more expensive.
