抵御侧信道分析的AES双路径掩码方法
AES Dual-path Masking Method for Resisting Side-channel Analysis
摘要
Abstract
In order to resist the side-channel analysis as power and EM attack, a dual-path masking method is proposed for Advanced Encryption Standard(AES) algorithm implementation. Through two data paths, the random numbers and random S-boxes are used to mask operation, which makes all intermediate variables among the proposed AES scheme different from that of the standard method, and the Hamming distance corresponding to each intermediate variable changes with the plaintext. It is simple in structure, and conducive to software and hardware implementation. Experimental result shows the correlation between the intermediates of standard AES and the energy characteristics of proposed AES scheme are completely removed. Thus, the proposed method bears strong immunity to all known side-channel analysis.关键词
