Are the traces resulting from the capturing considered power traces or voltage? I want to calculate the energy consumption. What I did was I treated the traces as voltage traces^2 divided it by 0.22(shunt resistance I assumed) then I got the area under the graph. Is that correct? I am using UFO Board and CWLITE Standalone.
The calibration that one would do with say an oscilloscope.
In side-channel attacks we only really care about relative differences in measurements; we don’t care about absolute measurements. That’s why CW isn’t meant to be used that way.
Very roughly yes/maybe, but not really. Google “AC coupling vs DC coupling” to learn more. ChipWhisperer’s measurements are best considered dimensionless.
If you want to measure power/current/power properly, then there are tools for this purpose, for example https://www.joulescope.com/ (no affiliation).
