Differential power analysis on FPGA board: Boundaries of success
Lukas Mazur, Martin Novotný · 2017
Differential Power Analysis (DPA) is a contemporary method able to break cryptographic device via measuring and analyzing its power consumption. The success rate of the DPA method strongly depends on the measurement setup. We have investigated and evaluated the influence of measurement setup on the success rate of DPA attack against FPGA board running AES encryption. From our findings it follows that removing decoupling capacitors plays major role in success rate of the DPA attack. Replacing standard switched-mode power supply with accumulators and linear stabilizers simplifies the attack, however, its effect is not that significant.
