How do I choose the claim of my attack?

You can test your attack on the fk0 dataset. If you did not train on it, then the number of traces needed to attack fk0 is a priori not different that the one needed to attack fk1.

That being said, for a given attack algorithm, some keys might be easier to break than some others, and maybe fk1 is easier or harder than fk0 for your attack. Please do not overfit your attack: develop it while evaluating only on fk0, and when it works there, test it on fk1. You may make multiple attempts at fk1 while chaning the number of attack traces, but your final number of traces should work for both fk0 and fk1.

I have another question.
