【摘要】：旁路攻擊對(duì)密碼芯片安全造成了嚴(yán)重威脅,是當(dāng)前研究的熱點(diǎn),但其存在分析時(shí)間過長(zhǎng)的問題,極大影響了實(shí)驗(yàn)效率。以差分功耗分析(differential power analysis,DPA)為研究目標(biāo),詳細(xì)分析了功耗軌跡樣本條數(shù)和樣本點(diǎn)數(shù)對(duì)程序特征的影響,找到程序中最耗時(shí)部分為功耗軌跡數(shù)據(jù)讀取,通過改進(jìn)數(shù)據(jù)的處理方式,將數(shù)據(jù)讀取次數(shù)降低為原程序的1/64。在改進(jìn)分析結(jié)果與原程序完全一致的前提下,獲得了高達(dá)39倍的加速比,大大提高了旁路攻擊的實(shí)驗(yàn)效率。
[Abstract]:Bypass attacks pose a serious threat to the security of cryptographic chips, and are the focus of current research. However, the analysis time is too long, which greatly affects the efficiency of the experiment. Taking differential Power Analysis (differential power analysis,DPA) as the research goal, the influence of the number of sample bars and the number of sample points on the program characteristics is analyzed in detail. The most time-consuming part of the program is the reading of the power consumption trajectory data, and the processing method of the data is improved. Reduce the number of data reads to 1 / 64 of the original program. On the premise that the result of the improved analysis is completely consistent with the original program, the speedup ratio of 39 times is obtained, and the experimental efficiency of bypass attack is greatly improved.
