| Abstract(in English) | This paper presents a high-resolution waveform alignment method using a Phase-Only Correlation (POC) technique and its application to side-channel attacks against cryptosystems. In general, power analysis attacks, such as SPA and DPA, require a statistical analysis of power waveforms to reduce noise and to retrieve secret information. However, the waveform data often include displacement errors in the measurement. The use of phase components in discrete Fourier transforms of waveforms makes it possible to estimate the displacements between signal waveforms with higher resolution than the sampling resolution. The effectiveness of power analysis attacks can be enhanced using the super-resolution alignment method. In this paper, we demonstrate the potential of the enhanced attacks through a set of experimental DPAs against DES software implementation on a Z80 processor. |
