Abstract
The Aim of this work is to enhance the side channel infor-mation that is revealed by the power consumption of a Field Programmable Gate Array (FPGA). An initial measurement setup is proposed for measuring the signal quality, and then adjustments and modifications to the hardware are done to enhance this quality. Once an acceptable signal is measurable, data is gathered and useful information in this raw data is determined using a standard leakage assessment methodology. The used methodology generates a quantitative score regarding the presence of useful information in the raw data, and can therefore indicate whether a system is vulnerable to side chan-nel attacks or not. In this work, several modifications are pre-sented along with their effect on the captured signal’s quality and the amount of useful information in the collected raw data.
