本文提出了一种新的安全智能卡硬件实现技术。所提出的策略是一种有效的对策，对非侵入性的攻击，如电源分析。它基于一个简单的子电路（Kocher等人，1999年），可以很容易地集成到智能卡芯片。事实证明，新技术可将任何数字电路所消耗的电力与内部详细数据解相关，从而避免在智能卡执行内部计算期间从智能卡提取秘密信息
This paper presents a new hardware technique for the realization of secure smart-cards. The proposed strategy represents a valid countermeasure against non-invasive attacks, such as power analysis. It is based on a simple sub-circuit (Kocher et al., 1999) that can be easily integrated into the smart-card chip. It has been proven that the new technique decorrelates the power consumed by any digital circuit from the internally elaborated data, thus avoiding extraction of secret information from smart cards during the execution of their internal computations
