功耗攻击是一种对加密芯片密钥进行攻击的方式,加密芯片功耗攻击与防御是目前信息安全的研究热点.但功耗分析的实验平台构建却比较困难,以DES加密算法为例,构建了一个基于AT89C51功耗攻击物理实验平台.详细叙述了物理实验平台的建立过程、注意事项、实验结果,该功耗攻击物理实验平台构建相对简单,实验运算速度较快,且具有加密算法易于修正的灵活性,可以方便地对加密算法的功耗特性进行改进与验证.%Power analysis attack has become a great threat to encryption chips. Attacks and defense of power analysis have be-come the research hotspot. However, experimental platform of power analysis is more difficult to build for researchers. This pa-per used DES encryption algorithm to build a high-performance AT89C51-based physical experiment platform for power analy-sis as an example, and described the process of establishing the physical experimental platform in detail. The platform is rela-tively simple , fast test speed, flexibility. It will be convenient to verified for the encryption algorithm of the power analysis attacks.
