Information leakage of electromagnetic emission from differential transmission lines

In this paper, information leakage from electromagnetic radiation of differential transmission lines is analyzed. The model of differential transmission lines is built. And common mode noise caused by unbalance structure of the differential transmission lines and delay between differential drivers is simulated. These common mode noises have a corresponding relationship with the information transmitted over the differential lines. It can cause information leakage. Finally, the experiment presents the possibility of information leakage from differential transmission lines.
