摘要
电磁信息泄漏问题给信息安全带来重大隐患,对电磁信息泄漏的研究具有重要意义和价值.针对用于计算机等信息设备的电源线电磁信息泄漏问题,研究基于电源线的电磁信息泄漏原理,建立了基于电源线的传导和辐射泄漏模型,并对基于双电流探头的测试方法进行了理论分析,最后通过实测数据对电源线电磁信息泄漏进行了验证分析.
The problem of information security is increasingly prominent with the ongoing development of information technology. Electromagnetic（EM） information leakage is a great hidden danger to information security,and research on the topic has great significance. 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.
