基于计算机技术对涉密信息的保护

随着计算机技术与网络技术的普及，中国已经正式进入了信息时代，但随之而来的通过计算机、网络造成泄密事件也与日俱增。文中通过对计算机技术泄密分析，解读了泄密途径主要通过电磁泄密、网络泄密和存储设备泄密等原因造成的。同时，提出了利用计算机技术手段确保涉密信息安全的防范策略、防范技术，最终利用密码、防火墙等相关技术确保涉密信息的安全。

Computer Technology-based Protection of Confidential Information

With the popularization of computer and network technologies, China has entered the information society. However, the incidents of secrets leakage through computer and network are thus increasing with each passing day. This paper, based on the analysis of secret leakage by computer, points out the main leakage approaches, including the electromagnetic, network and storage media. It focuses on the computer-based defending strategy and technologies, particularly the cryptographic technology, for protection of confidential information.
