don't panic. Just because something works in a lab, does not mean that it |

works outside of it too. So they were able to freeze some ram and get some |

information of it. So what? First of all - how man times will someone be able |
7 |
to steal a computer and freeze its ram seconds after it was shut of? Who |
8 |
guarantees that the decayed parts are not the ones holding the key? even a |
9 |
couple of flipped bits make the data useless. And who guarantees that the |
10 |
dram survives the forces when it is cooled down in tens of seconds and heated |
11 |
up (through the current) afterwards? |

With a logic analyzer you can steal keys from the cpu cache by measuring the |
14 |
time used for certain instructions. Oh no! And with the right tools you can |
15 |
crack the chips on EC-cards. |
