A study on risk evaluation of countermeasure technique for preventing electromagnetic information leakage from ITE

A telecommunication equipment and information technical equipment usually produce unintentional electromagnetic fields. Information from a video display unit could be reconstructed by intercepting such emissions at a distance. The testing methods and countermeasure methods have been discussed and those standardizations have been published at ITU-T SG5 WP2, and ITU-T K.115: Mitigation methods against electromagnetic security threats has also published in Oct. 2015. In this paper, a risk evaluation method of countermeasure technique for preventing electromagnetic information leakage is studied.
