密级标识技术的研究

Research on Secret Labeling Technology

电子文档的保密管理、访问控制、跟踪和审计,是企事业单位内网安全的关键和薄弱点。如何构建多级安全系统已经成为急需解决的问题,而密级标识技术是解决这个问题的关键。通过研究电子文档密级标识的密码学需求、标识原理以及标识方案设计与实现,旨在解决企事业单位内网传递过程中对内部文件、重要数据等敏感电子文件从创建、分发乃至销毁的全过程进行控制和保护,确保这些文件即便被黑客盗取或内部人员有意外泄,获得者也无法打开,从而切实保障内网传递过程中的信息安全。

The key and weak point of Intranet Security in enterprises and institutions is the secure management,access control,tracking and auditing of electronic documents. How to build a multi-level security system has become an urgent problem to be solved,and the key to solve this problem is the secret level identification technology. By studying the cryptographic requirements,identification principles and the design and implementation of identification schemes of electronic document classified identification,the purpose is to control and protect sensitive electronic documents such as internal documents and important data in the process of Intranet transmission in enterprises and institutions from the whole process of creation, distribution and even destruction. Ensure that even if these documents are stolen by hackers or leaked by internal personnel,the acquirer cannot open them,so as to effectively protect the information security in the process of Intranet transmission.
