摘要

En 中文
RSA的模幂运算是公钥基础设施中的基本操作，自然是侧信道攻击的目标。在这项工作中，我们提出了两种克服侧信道攻击的算法: 配对置换指数 (PPE) 和置换，拆分和累积 (PSA)。我们将这两种算法与经典的从右到左技术进行比较。所有这三个实施都使用英特尔 (R) 性能计数器监视器 (PCM) 以0.25毫秒的有效采样间隔进行评估。我们使用固定的2048位输入，将Python 3.9.13进程固定到单核Intel (R) core (TM) i5-10210U，并重复每个实验100和1000次，以表征行为和集合统计数据。相对于标准RtL，我们提出的技术PSA显示出最低的运行时间和针对每位相关性的最强硬化。与指数的汉明权重有关的残余泄漏可以保持可观察的，但是所收集的唯一信息是秘密密钥的汉明权重。秘密密钥位的确切位置被完全遮蔽。
