Consideration of the side-channel attack to SIMON implemented on Arduino Uno

Abstract

In this research, the authors conducted the side-channel attack (SCA)for the XOR in the final round of "SIMON." As of 2021, there is no research about side-channel attacks against SIMON, which makes this paper more worthwhile. As a result, the authors could attack with little computational resources and time, which means that "SIMON" can be weak against side-channel attacks. Furthermore, the authors checked the relationship between the hamming-weight of the round key and the easiness of attacking. The authors confirmed that there was no relationship between them.
