A processor can leak information by different ways [1], electromagnetic radiations could be one of them. This idea, was first introduced by Kocher, with timing and power measurements. Here we developed the continuation of his ideas by measuring the field radiated by the processor. Therefore we show that the electromagnetic attack obtains at least the same result as power consumption and consequently must be carefuly taken into account. Finally we enumerate countermeasures to be implemented.
