Issues of this thesis are focused on side-channel cryptanalysis. Particularly attention is paid to differential power analysis, when is simulated an attack on the cryptographic module for different conditions and for different structural features of this module. As the cryptographic module is used a PIC microcontroller, which is operating with AES symmetric encryption algorithm. For this purpose, a design of experimental printed circuit board was created. Then, this PCB was equipped only with the necessary components for the function of the cryptographic module. Cryptanalysis is aimed on current consumption of crypto module that is caused by execution of AddRoundKey instructions. Power consumption of PIC microcontroller is measured in depending on the size of power supply voltage, size of serial resistor, size of bypass capacitor, and this thesis also examines the influence of ambient temperature on power consumption of PIC. The measured values are graphically presented and then discussed.
