基于实体行为依赖关系的完整性度量方案

针对由于交互行为而导致的安全威胁,以及现有完整性度量方案在度量范围和度量内容上的不足,从实体行为的角度出发,分析了实体行为之间的依赖关系,构建了实体行为依赖集合。提出了一种基于实体行为依赖关系的完整性度量方案,在实体行为依赖集合上定义了实体行为完整性度量函数,以及实体行为预期符合函数,最后给出了交互行为之间进行完整性度量和验证的具体过程。该方案从实体行为的实体完整性和数据完整性两个方面进行度量,改进了现有完整性度量方案的不足,增加了完整性验证的灵活性。

Integrity Measurement Based on Dependence Relationship of Entity Behaviors

For the security threats based on interactive behaviors and from the view of entity behaviors,the dependence relationships between entity behaviors are analyzed,the entity behaviors dependence set is constructed. And based on this,an integrity measurement scheme based on dependence relationship of entity behaviors is proposed, the entity behaviors measurement function is defined on the set of dependent entity behaviors,including the expectation conformity function of entity behaviors. Finally,the specific process for integrity measurement verification between interactive behaviors is given. The proposed scheme improves the performance of existing integrity measurement schemes,and raises the flexibility of integrity verification.
