Researchers from three groups on Thursday published research showing that disk-based encryption schemes across multiple operating systems can be circumvented to reveal protected data.
In the paper, "Lest We Remember: Cold Boot Attacks on Encryption Keys," the researchers from Princeton University, the Electronic Frontier Foundation, and Wind River Systems revealed that computer memory, contrary to popular belief, retains data for a brief period after a computer is turned off and that cooling memory chips can prolong the persistence of data in memory.
