I think I have missed something very fundamental.
I am trying to understand the step in DPA where you compare your hypothetical power consumptions with your measured ones. The Matrix H with Matrix T.
Matrix T is of size D x T, where D is the number of data blocks and T is the number of measured points in one power trace. This implies that an element value in this matrix T can be of 0.58W (just an example).
If I use Hamming Weight, as power model, I will end up with a real number. E.g., 0110 0111 = 5 (dimensionless). How can this number correlate with the power traces that are in Watts? (e.g., If I use Pearsons).
