涉密电子文件安全标识的设计与管理

摘要

Because of security level identification don' t support dynamic changes of the attribute information , no unified structure and the form of access control is signal, this paper designs a general structure of secur- ity level identification which is refinement and can be used in full life cycle of electronic document' s securi- ty ; Then, due to the dynamic characteristics of the attribute information, this paper presents a security level identification management based on database.%本文针对安全标识不支持属性信息动态变化、暂无统一标识结构以及安全属性信息单一等问题，设计了一种细化的、可用于涉密电子文件全生命周期安全可控的安全标识结构；其次针对改进后标识属性信息动态性的特点，提出了一种基于数据库的安全标识管理方案。
