multilevel secure meaning in English
多级安全
Examples
- A generic audit policy model on multilevel secure dbms
的通用审计策略模型 - We use polyinstance to eliminate the covert signal channel in the multilevel secure database , so we must change the traditional relational data modal
本文引入了多实例以解决多级数据库中的隐蔽信号通道，因此必须对传统的关系模型进行根本变革。 - Database security theory and technology is an important research field of database theory . in this paper , we focus on secure data modle , inference control and transaction processing in multilevel secure environment
如何保护数据库的安全成为信息安全中一个重要的研究方向。数据库安全理论和技术是数据库理论研究的重要方向。 - First of all we introduce the concept of the secure database and classification of the secure database , then we introduce the concept and research current situation of the inference channels in multilevel secure database . we describe some methods to detect and eliminate inference channels
本文首先介绍了安全数据库的概念和安全数据库的分级，然后介绍了推理通道的概念以及多级安全数据库中推理通道的研究现状，并且描述了一些检测和消除推理通道的方法。 - First , by analysing the disadvangtages of the decomposition and recovery algorithm in the usual security model , a new algorithm of double structure tables , which is suitble for master - slaver structure tables , is presented in this paper . second , in resolving the semantic ambiguity and operational incompleteness easily emerged in master - slaver structure tables , an improved master - slaver structure table model and relative decomposition and recovery algorithm are provided . third , considering the merits and demerits of security model , a multilevel secure transaction model is defined on the basis of security model
本文通过分析以往安全模型的分解和恢复算法的缺点,提出了一个适合于主从结构表这种双结构表安全模型的分解和恢复算法;针对主从结构表安全模型容易产生语义模糊性和操作不完备性等问题,提出了一个改进的主从结构表安全模型,并提出了其分解和恢复可行方法;讨论了安全模型的优缺点,定义了建立在安全模型基础之上的多级安全事务模型,分析了多级事务面临的众多难题,提出了一个安全、正确的多级事务调度算法;根据上述的诸多理论,开发了一个多级安全数据库管理系统的原型系统。
