摘要
相关性功耗分析攻击是破解密码芯片密钥的有效方法,现有的CPA攻击缺少有效的仿真验证工具和高效一体化、易用的实验平台。在分析了CPA攻击原理及功耗模型的基础上,设计了一个针对密码芯片的相关性功耗分析实验平台,成功的对普通AES、固定值掩码AES、循环S盒掩码AES加密算法进行了相关性功耗攻击。实验证明,该平台操作简单,实现了数据处理的并行性,提高了功耗攻击的准确度和效率。
Correlation power analysis attack is an effective method to crack the key of cipher chip.The existing CPA attack lacks effective simulation tools and an efficient and integrated experimental platform.By analyzing the CPA attack principle and power consumption model,developed a correlation power analysis experiment platform for cryptographic chips,and successful implementation of correlation power attack on AES,fixed value mask AES,and rotating S-Box masking AES encryption algorithm.The experiments show that the platform is simple,has realized the data processing of parallelism,enhance the accuracy of the attack power consumption and efficiency.
