RAM: Rapid Alignment Method

Abstract : Several countermeasures against side-channel analysis result in misalignment of power traces, in order to make DPA more difficult. In this paper we propose a new algorithm to align the measurements after this desynchronizing through the variations of the internal clock, random delays, etc. The algorithm is based on the ideas of SIFT and U-SURF algorithm that were originally proposed for image recognition. The comparison with other known methods favors our solution in terms of efficiency and computational complexity.
