This [password retrieval article](http://www.heise.de/newsticker/Passwortklau-durch-gekuehlten-Speicher–/meldung/103908) makes me think about data-encryption… Is encryption in vain? Is hardware this insecure? Though the article is in german you can find the original Princeton paper in english at the bottom of the page.
Tell me what you think about it.
Update: The link at heise.de seems to be down – use this link instead: [Lest We Remember: Cold Boot Attacks on Encryption Keys](http://citp.princeton.edu/memory/).
