File:Power attack.png
Summary
Power variations, observed during work of the embedded processor, computing <a href="//commons.wikimedia.org/w/index.php?title=RSA&action=edit&redlink=1" class="new" title="RSA (page does not exist)">RSA</a> signatures. The left (short) peak represents iteration without multiplication (key bit is cleared), and the right represents iteration with multiplication (key bit is set). The low power pause between iterations has been artificially implemented to make key decoding trivial. This would be more complex on the real world devices that, differently, try to obfuscate it. This is a trimmed version.
