| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The threat of TEMPEST attack which reconstructs the screen information from the electromagnetic leakage caused by operation of display has been reported. The intensity of electromagnetic leakage from these devices is dependent on the surrounding environment, such as used place and peripheral devices. Thus, leakage intensity evaluation is required under different usage environments. In this paper, we clarify the factors that affect the leakage intensity of screen information by altering the surrounding environment of laptop PC. In this experiment, to evaluate the effect of usage environment on information leakage from laptop PC, we used a method that displays an image containing specific frequency components on amplitude demodulated wave which obtained from received electromagnetic waves and compares their spectrum intensity. As a result, we confirmed that the leakage intensity changes in the various surrounding environment. In addition, leakage intensity is increased when we put the laptop PC on a metal plate at a specific leakage frequency. |
