Summary:
The image displayed on a personal computer can be reconstructed by receiving the conducted emission on its power leads. This is one of threats for information leakage in information security. So, we would like to evaluate quantitatively the information leakage. In this paper, we propose a measurement method of the information signal conducted emitting from power leads of a PC. In order to check the validity of the proposed method, experiments were carried out. These results have shown the correspondence with the reconstructed images and the measured levels .
