容易被忽视的信息泄密隐患初探及其防护

Preliminary Study and Protection of Easy Neglectful Hidden Trouble of the Information Secret Divulgence

当今社会已进入信息时代,网络应用蓬勃发展,人们日常工作生活对计算机信息系统的依赖性很强,因此产生的信息泄密所致后果的严重性超乎想象。文中通过研究计算机信息系统的电磁泄漏的机理,特别是具体分析了计算机及其外部设备的信息电磁泄漏的基本原理,得出电磁泄露可能带来信息泄密隐患的结论,并讨论了一些防止计算机信息系统电磁泄漏的实用技术和有效方法,介绍了TEMPEST技术及其发展情况。相信随着各类计算机信息系统设备在各个领域的普遍应用,计算机信息系统电磁泄漏泄密的问题将会越来越得到重视,防电磁泄漏的技术手段将会不断快速发展。

Society have already entered an information for ages nowadays, the network application boom widely. In the daily life, people is very strong to the dependence of the calculator information system, so the output information of a secret divulgence will bring a serious effect. This paper researches the mechanism that the electromagnetism of the calculator information system leaks, concretely analyzing the basic principle of the calculator and its exterior equipments the information electromagnetism leak, reveal the conclusion that may bring a hidden trouble of a secret divulgence, and discusses some practical techniques that prevent the electromagnetism leak of calculator information system with the valid method. This paper introduces the TEMPEST technique and its development circumstance . Believe along with each kind of calculator information system equipments at the widespread application of each realm, the calculator information system electromagnetism leakiness problem will get a value more and more, the technique that defends the electromagnetism leakiness will develop continuously and quickly.
