Side-channel attacks pose a critical threat to the deployment of secure embedded systems. Both the academic and industrial communities have devoted considerable effort in order to evaluate the feasibility and effectiveness of these attacks. Differential-power analysis is a well-documented, powerful side-channel attack technique, which relies on measuring the power consumption of secure device (e.g. smart card, tamper-resistant circuits) while it computes a cryptographic primitive. These measurements are performed employing a digital oscilloscope and off the shelf components in order to tap into the power supply line of the device.
