		kylemaxwell on May 30, 2011 \| parent \| context \| favorite \| on: Tresor Runs Encryption Securely Outside RAM It's really interesting to see this, as I've had concerns for a while now about keys getting read from memory (while helpful in incident response). Though I wonder if sufficiently privileged processes might not be able to read those registers?

Userland processes can't directly read the debug registers.

Absolutely. Then again, assuming that you can't get from root to kernel on a Linux box seems somewhat optimistic. Still a cool hack, though.
