基于面向对象信任攻击图的信任风险传播模型
Trust Risk Propagating Model Based on Object-oriented Trust Attack Graph
摘要
Abstract
In order to study the trust attack problem in complicated trust environment, the object-oriented trust attack graph model is put forward. In the model, the rule take, grant and pervade are used to describe trust level escalating, trust relation transiting, pervading and spreading resulting from utilization of vulnerabilities existing in attributes of trust entity objects, therefore a longer attack reachable distance can be reached. The model carries the attack complexity and harmfulness index which are used to determine the attack threat index, the vulnerability utilizing rules and trust relation embezzling rules are used to establish the trust relation transitive closure generating algorithm with polynomial time complexity, based on which a trust risk propagating algorithm is established. Through an experiment based on modeling real vulnerabilities for a system, the model is proofed to be correct.关键词
