| 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: | Side Channel Attack(SCA) takes great threat to cryptography chip, which is a hot topic of research. But the time of data analysis is too long, which greatly lowers experiment efficiency. Procedure of Differential Power Analysis(DPA)is researched. Effects to program character of power track number and sample point number are studied in detail. The major part of program running is data read of power track. With the optimizing of data processing, passes is reduced to 1/64 of original. Correctness of result is tested. The acceleration ratio of optimized program achieves 39, which greatly improves efficiency of experiment. |
