Moreover, we introduce a framework to evaluate the soundness of the new first-order masking when the leakage slightly deviates from the rules involved to design the countermeasure. It reveals that the countermeasure remains more efficient than the state-of-the-art first-order masking if the deviation from the ideal model is equal to a few tens of percents, and that it is as good as a first-order Boolean masking even if the deviation is $50$\%.
