New Kind of Attack to Cryptographic Systems

It's always very exciting to see how people manage to think out of the boxes which we perceived as safe and black by the great majority of experts. The new kind of attack is based on the actual properties of DRAM chips which are based on capacitors which discharge over long enough period of time to read the former content of memory even after reboot. It's interesting to know that DRAM cells are though to discharge so fast that for normal operation of DRAM the memory content is supported by recharging the capacitors every 64ms. This also means that one machine is rebooted the old memory content is kept until it's explicitly cleared.
