随机探测安全性的具体评价

Concrete Evaluation of the Random Probing Security

Vahid Jahandideh, Amir Daneshgar, Mahmoud Salmasizadeh

摘要:

我们研究了当对手随机探测其每个内部变量时,掩码实现的安全性,旨在恢复有关其秘密的非平凡知识。我们引入了一种新的度量,称为秘密恢复概率(SRP)的信息性评估的探测泄漏的掩盖秘密。为了评估SRP,我们的出发点是用奇偶方程系统描述中间变量之间的关系,其中目标秘密是这个系统的未知数。

英文摘要:

We study masked implementation's security when an adversary randomly probes each of its internal variables, intending to recover non-trivial knowledge about its secrets. We introduce a novel metric called Secret Recovery Probability (SRP) for assessing the informativeness of the probing leakages about the masked secrets. To evaluate SRP, our starting point is to describe the relations of the intermediate variables with a parity equation system where the target secret is an unknown of this system ...
