发布时间：2018-10-11 19:07
【摘要】：旁路攻击对密码芯片安全造成了严重威胁,是当前研究的热点,但其存在分析时间过长的问题,极大影响了实验效率。以差分功耗分析(differential power analysis,DPA)为研究目标,详细分析了功耗轨迹样本条数和样本点数对程序特征的影响,找到程序中最耗时部分为功耗轨迹数据读取,通过改进数据的处理方式,将数据读取次数降低为原程序的1/64。在改进分析结果与原程序完全一致的前提下,获得了高达39倍的加速比,大大提高了旁路攻击的实验效率。
[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.
