| Abstract(in English) | Recently, a lot of attack methods which target information leakage via electromagnetic emanation from information devices are developed, and causes real threats for information devices. Applying the EMI model to mechanism of the electromagnetic information leakage on information device, we can treat the transient current released from mounted modules as the Source; and the substrate of the device and the lines attached to the substrate as the Path and the Antenna. The authors showed a PCB and some attached lines in the information device behaves as band filter, but the mechanism is not clear. In this report the authors measure the influence of these circuit elements for frequency characteristic of the band filter focusing on inductance and capacitance of the attached lines. Our goals are giving clarified mechanism of the band filter and proposing guideline to suppress the electromagnetic information leakage from information devices. |
