TEMPEST testing is to acquire the electromagnetic emanations such as emission intensity, parasitic leakage, signal bandwidth, characteristics in time domain and frequency domain, etc, by special equipments then rating security level. Computer and other digital electronic equipments can emit unintentional electromagnetic signals in the state of information processing. The compromising electromagnetic emanations allow eavesdroppers to reconstruct processed data at a distance that threatening the information security. As result all equipments handling confidential information do need TEMPEST security testing. This paper attempts to design a mathematical model for TEMPEST testing that will facilitate the analysis of the key factors in TEMPEST testing and standard revising.
