doi:10.3969/j.issn.1671-1122.2018.05.006

Abstract

Abstract:

SM4 is a block cipher used in wireless LAN products. This paper mainly studies the power analysis on SM4 cipher implemented in hardware, and proposes a novel chosen-plaintext method power analysis attack based on Welch's t test and principal component analysis.This paper achieves an attack of SM4 on FPGA in ChipWhisperer experimental platform. The results show that this method can effectively reduce the number of power consumption waveforms required for a successful attack,and reduce the complexity of analysis.

Key words: SM4, power analysis, hardware implementation, ChipWhisperer
