I thought the members might be interested in this new disc encryption hack that super cools the DRAM so it retains encryption keys longer. Very unique and it works.

It's been a hot topic in certain circles for a little while now. Bruce Schriner has brought it up as well. It's about time it showed up here. Thanks for bringing up. That link that you posted is the best I've seen yet. My take. It can be an excellent tool, in a lab enviroment for forensic work, but in the wild, I wouldn't put much faith in this process. But still, just knowing that the possibility exists... something to make a person think. -d

I wonder why the concept hasn't been demonstrated before, perhaps for different reasons.

Yes it is doable but likely, not.

My take on whole drive encryption is that you must have a backup plan. Yea if you have a pc in the lab you can break the key, but in the real world you have a pc with a hard drive problem, it will not boot, it has been on and off for several days.. no chance of grabbing the key from memory.

You can however if it is your pc and you have access to a decryption key, access the hard drive, but wait, the drive is bad and failing badly, in my experience the data recovery rate is somewhat low. I have saved data in such a situation but it was a long and painful process.

Guess that I am stepping off the topic but I just wanted to say that without a good backup system for your encrypted drives your data is safe, even from yourself, you may never see it again.
