| 摘 要： | 样本量是可以衡量设备抵 CPA攻击的重要指标,因此建立一种计算样本量的模型是很重要的.选择用统计学的方法通过计算样本量测定硬件的防护效果,这就可以让设计者在设计过程中通过计算了解设备抵御CPA的能力,还可以很容易地比较不同的防护方法,避免了由于产品不能有效抵 CPA攻击而进行的代价高昂的重复设计.

| Abstract: | The number of samples is a important index which weighs the resistance of their devices a-gainst CPA attacks,so it is meaningful to establish one model to calculate the number of samples.Chooses a statistical approach to determine the effect of hardware countermeasures on the number of samples needed in CPA attacks.This approach results in a calculation method that enables designers to assess the resistance of their devices against CPA attacks throughout the design process.This way,different combinations of... |
