摘要
智能卡是一种可防止被入侵设计的设备,为了防止攻击者藉由边际信道泄漏信息,如功率消耗、执行时间、故障时的输出与输入行为、电磁辐射、功率尖峰情形等信息攻击智能卡,必须采取一些防备措施。本文主要介绍攻击智能卡的简易功率分析(SPA),微分功率分析(DPA)。这些技术已被广泛地使用于窃取智能卡保护数据的技术上,提供这些技术的概略性观念,使我们知道问题所在,进一步想出对策,促使我们设计出更安全的智能卡。
The smart card is a kind of equipment that can prevent from attacking,in order to prevent from side -channel attacking, such as power consumption, execution time, breakdown output and input behavior, electromagnetic radiation and power peak situation. So it must take some protection measures. This paper introduces attacks about Simple Power Analysis （SPA） and Differential Power Analysis （DPA）.These technologies have been widely used in steal the smart card protection data in the technology. This paper introduces the idea of these technology,causes us to know the question ,further finds out the countermeasure, urges us to design the safe smart card.
