Also there are some very sad people who reverse engineer systems by monitoring the power consumption of a device as it is running a routine and cross correlate the power consumption with known power consumption signatures and work out what operations are going on.Sounds strange but its true.


That's one I didn't know about! What I do know is that it is possible to use the peaks in the device current to get the DES keys from a smartcard. This method is called Differential Power Analysis or DPA for short.

This, of course, has nothing to do with the topic of this post which has been discussed before in this post.
