Abstract :
Simple power analysis attacks with chosen-message techniques were applied to an RSA processor implemented with standard CMOS technology on ASIC, and the different characteristics of power waveforms caused by two types of implementation (ASIC and FPGA) were investigated in detail. We also applied comparative power analysis an advanced power analysis attack in which a pair of input data was used to enhance the waveform pattern for modular exponentiation. The power dissipation of modular squaring in the difference waveform was greatly reduced when compared to modular multiplication, allowing all of the secret key bits to be successfully revealed.
