Original Abstract

The article describes the optimization of differential side channel analysis which is often used in differential power analysis. The introductory chapters discusses in great detail the theoretical background of method. The new improvement is proposed, which allow reduction of the required calculations by 73% and it is in the worst case. The method is based on knowledge of the Hamming weight of secret key. Hamming weight of secret key can be determined by adding only one reference measurement of power consumption. The testbed focused on measuring direct emissions was built to verify proposal optimization and experimental verification was carried out.
