对密码算法硬件实现的相关功率分析(CPA)攻击可以通过分析假设密钥与该密码硬件的功率测量之间的相关性来检索密码密钥。现有的CPA攻击和对策主要针对二维集成电路(IC)。在三维(3D)集成电路的背景下，缺乏对CPA的研究。为了填补这一空白，本工作研究了3D配电网络(PDN)对安装在3D平面上的密码模块上的CPA效率的影响。使用皮尔逊相关系数作为度量来评估不同的PDN类型、电路负载和相邻平面的切换活动对CPA效率的影响。
Correlation power analysis (CPA) attacks on the hardware implementation of cryptographic algorithms can retrieve the cipher key by analyzing the correlation between hypothesized keys and the power measurement of that crypto hardware. The existing CPA attacks and the countermeasures are mainly for two-dimensional (2D) integrated circuits (ICs). There is a lack of study on CPA in the context of three dimensional(3D) ICs. To fill in this gap, this work investigates the impact of a 3D power distribution network (PDN) on the efficiency of CPA mounted on a cryptographic module, which is in one of the 3D planes. The Pearson correlation coefficient is used as a metric to assess the impact of different PDN types, circuit loads, and switching activities of the neighboring planes on the CPA efficiency.
