This paper presents an efficient map generation technique for evaluating the intensity of electromagnetic (EM) radiation associated with information leakage for cryptographic devices at the printed circuit board level. First, we investigate the relation between the intensity of the overall EM radiation and the intensity of EM information leakage on a cryptographic device. For this purpose, we prepare...
This paper presents an efficient map generation technique for evaluating the intensity of electromagnetic (EM) radiation associated with information leakage for cryptographic devices at the PCB level. First, we investigate the relation between the intensity of the overall EM radiation and the intensity of EM information leakage on a cryptographic device. For this purpose, we prepare a map of the magnetic...
In this paper, we present a method for selecting a specific set of acquired EM traces with the aim to improve the efficiency of EM analysis. The proposed method improves the correlation factor by using a set of selected plaintexts. We demonstrate the efficiency of our method through correlation electromagnetic analysis (CEMA) experiments conducted using SASEBO. The results clearly show the impact...
