一种基于多维信任度的Web跨域访问控制方法
cross-domain access control method of Web service based on Multi-dimensional trust measurement
针对当前引入了信任机制的访问控制模型所存在的信任度表征形式单一、没有对用户主观贪婪欲加以限制等问题,提出一种基于多维信任度的访问控制方法。模型中利用需求向量表征节点对网络资源的需求度、利用信任向量表示节点所能提供网络服务的能力,以基于角色的访问控制方法为前提,根据信任向量对需求向量进行约束性更新,并引入角色控制参数对恶意节点的恶意行为做出惩罚,从而对用户、尤其是恶意用户,在使用网络资源时所产生的主观占有意识加以限制,保障了系统的安全性。通过模拟仿真实验表明,此方法提高了节点间交互的成功率并降低了系统性能的开销。?????
In view of the problem in existing trust models including single credibility depiction, no limit to the user's desire to be greedy. This paper proposes a cross-domain access control method of Web service with multi-dimensional trust measurement. The model uses the demand vector to characterize the degree of the node's demand of the network resources ,uses the trust vector to characterize node's ability to provide network services, based on the existing role access control model, the role of control parameters is introduced when the node generates a demand vector, to users ,especially to malicious users , in use of network resources generated by the subjective sense of possession to be restricted, ensuring the security of the system 。Simulation results show that the introduction of multi dimension trust degree improves the success rate of interaction between nodes and the use efficiency of network resources.?????
