基于AT89C51物理功耗攻击实验平台研究

Research of power analysis physical experiment platform based AT89C51

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 become the research hotspot.However,experimental platform of power analysis is more difficult to build for researchers.This paper used DES encryption algorithm to build a high-performance AT89C51-based physical experiment platform for power analysis as an example,and described the process of establishing the physical experimental platform in detail.The platform is relatively simple,fast test speed,flexibility.It will be convenient to verified for the encryption algorithm of the power analysis attacks.
