چکیده
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. Streszczenie. W artykule opisano metodę optymalizacji różnicowej analizy mocy. Metoda bazuje na znajomości wag Hamminga. Są one określane przez dodanie jednego pomiaru poboru mocy odniesienia. (Optymalizacja różnicowej analizy mocy)

Some significant characteristics of differential currents in the real PT operating circumstances are extracted. In this paper, Multi Resolution Analysis (MRA) is use...
متن کاملDifferential Power Analysis: A Serious Threat to FPGA Security
Differential Power Analysis (DPA) implies measuring the supply current of a cipher-circuit in an attempt to uncover part of a cipher key. Cryptographic security gets compromised if the current waveforms obtained correlate with those from a hypothetical power model of the circuit. As FPGAs are becoming integral parts of embedded systems and increasingly popular for cryptographic applications and...
