Sažetak
S-boxes are usual targets of side-channel attacks and it is an open problem to develop design techniques for S-boxes with improved DPA resistance. One result along that line is the transparency order, a property that attempts to characterize the resilience of S-boxes against DPA attacks. Recently, it was shown there exist flaws with the original definition of transparency, which resulted in the new definition - modified transparency order. This paper develops techniques for constructions using the modified transparency as a guiding metric. For the 4×4 size, we significantly improve modified transparency order while remaining in the optimal classes. Experimental results are provided assuming a noisy HW leakage model to show the proposed S-boxes are more resistant than the original one of the PRESENT algorithm. We conclude with reports on 4×4 and 8×8 S-boxes where the results indicate that the modified transparency order could be a more useful metric than the transparency order. However, both measures are far from definitive solution on how to improve the DPA resistance.
