In this paper, we propose a setup that improves the performance of implementation attacks by exploiting the difference of sidechannel leakages. The main idea of our setup is to use two cryptographic devices and to measure the difference of their physical leakages, e.g., their power consumption. This increases the signal-to-noise ratio of the measurement and reduces the number of needed power-consumption traces in order to succeed an attack. The setup can efficiently be applied (but is not… CONTINUE READING
