Simulation-Based Approach to Target EMI Attenuation for Meeting Required Power Side-Channel Attack Success Rate

Side-channel attacks (SCAs) can recover the cryptographic secret keys from electromagnetic interference (EMI) conducted on the power delivery network (PDN). Focusing on the simulation-based secure PDN design, we previously applied simulated switching current sources in ICs to calculations of the targeted EMI attenuation. In this paper, focusing on the Correlation Power Analysis (CPA) as an SCA, we use the theoretical formula of the attack success rate (SR) of CPA to calculate the target EMI attenuation to meet the required SR of CPA. Since SR indicates the realistic CPA risk, this target attenuation provides more accurate and reliable assessment.

Abstract

Side-channel attacks (SCAs) can recover the cryptographic secret keys from electromagnetic interference (EMI) conducted on the power delivery network (PDN). Focusing on the simulation-based secure PDN design, we previously applied simulated switching current sources in ICs to calculations of the targeted EMI attenuation. In this paper, focusing on the Correlation Power Analysis (CPA) as an SCA, we use the theoretical formula of the attack success rate (SR) of CPA to calculate the target EMI attenuation to meet the required SR of CPA. Since SR indicates the realistic CPA risk, this target attenuation provides more accurate and reliable assessment.
