Modeling and experimental research on electromagnetic information leakage from power lines

The problem of information security is increasingly prominent with the ongoing development of infor-mation technology. Electromagnetic (EM) information leakage is a great hidden danger to information security, and research on the topic has great signi cance. In this paper, the principle of power line (PL) EM information leakage in computers is studied. PL conduction and radiation leakage models are built. Experimental analysis is implemented to further prove the potential harmfulness to security of EM information leakage from PL.
