Hello,



==========

Problem:



Everything is stored in plaintext in the Memory.



So if although full disc encryption is used on a Linux Desktop, it is possible to copy the content of the memory, while the notebook was on suspend or it was running:



https://citp.princeton.edu/research/memory/media/



==========

Solution:



Can we (optionally*) encrypt the content of the memory and store the key for decryption in the CPU to avoid in general these kind of attacks?



https://www1.informatik.uni-erlangen.de/tresor



Is this solution already in the Linux kernel? If yes, how can a Linux enduser turn it on? If no, how can we get the code/idea in the mainline? What are the arguments against it?



*if someone would want to harden it's Linux Desktop (since notebooks could be stolen..) it could turn on this feature to avoid a policy to always turn off the notebook while not using it.



Thank you for your comments.
