Given the ubiquity of embedded devices in modern society, strong cryptographic solutions are a necessity to ensure privacy and security. In addition to the challenges that traditional cryptography faces, embedded cryptography is more vulnerable to side-channel attacks due to its location in the hands of the (un)trusted user. We propose that adjusting the mathematical properties of the cryptosystems can affect the information leakage through these side-channels. Our experimental results confirm that the information leakage from power side-channels is heavily affected by both the mathematical structure as well as discrete implementation choices.
