摘　　要：差分功耗分析攻击利用嵌入式加密系统功耗泄漏信号来获取加密系统密钥,将穷举问题转化为数据采集、处理问题。在对DES加密嵌入式系统攻击实验中,基于虚拟仪器的差分功耗分析平台令差分功耗分析攻击的数据采集过程由虚拟仪器应用程序控制进行,而后再对采集的功耗进行分析,能够快速、准确地找到加密系统密钥。较传统的穷举攻击而言,减少了消耗的时间和成本。Differential Power Analysis （DPA） attack can be used to find the keys of embedded encrypted system by detecting the leaking power consumption of the encrypted system. DPA attack converts the exhaustive work into a work of data acquisition and data analysis. In the attacking experiment on the embedded DES encrypted system, the platform based on virtual instrument （VI） was implemented to control the data acquisition process of DPA attacking. Then the data were analyzed to find the key of the system quickly and correctly. Comparing with traditional exhaustive attack, the proposed DPA platform based on virtual instrument needs much less time and money cost.
