电子政务中电子文件信息安全探析

A Probe into the Information Security of E-Documents in E-Government

随着社会信息化进程的加快,电子政务已被世界各国列为优先发展的战略项目。电子政务的发展是建立在信息安全基础之上的,而电子文件信息安全又是电子政务信息安全的重要内容。电子文件信息安全是指对电子文件信息内容的保密性、完整性、可用性、可控性和不可否认性进行的安全保护。电子文件信息的非人工直读性、系统依赖性、信息与特定载体之间的可分离性、信息的可变性、信息存储的高密度性、多种媒体信息的集成性以及信息的可操作性等特性,使得电子文件内容信息的安全性难以保障,也使电子文件的凭证作用遭到人们的质疑;同时还存在载体和软硬件设备完好无损而电子文件信息内容无法读出的可能和保存的电子文件信息因遭黑客侵扰、计算机病毒破坏而丢失或损坏的危险。为此,需要加强对电子文件信息安全的保护,防止电子文件信息被非法变更与破坏。应该在分析电子政务中影响电子文件信息安全的主要因素的基础上,从技术手段、管理方法和法律法规三个方面探讨保障电子文件安全的措施。

With the expediting of socialization and informationization, e-government has been ranked by all countries in the strategic prior project. While the development of e-government bases on the information security, the information security of e-documents becomes an important part of the information security of e-gov- ernment. The information security of e-documents refers to the safety protection for the privacy, completeness, availability, controllability and non-repudiation of the electronic information content. Since e-documents are characteristic of non-artificial direct-reading, system dependence, separation between information and specific carrier, information diversity, high density storage, multimedia integration and information maneuverability, not only is the e-document content difficult to be safeguarded, but also the credence function is questioned. At the same time, there is possibility that the e-document content is unable to be read although the carrier, software and hardware are all safe and sound, and also there is the danger of e-document information lost or destroyed due to the hacker＇s intrusion or virus breakage. Therefore, it is necessary to strengthen the safeguard of e-document information and prevent the e-document information from being illegally falsified or destroyed. Also more attention should be paid, by analysis of the main factor influencing the security of e-document information in e-government, and from the three aspects of technology, administration and law, to the probe into the informational safety of e-documents.
