网格域间信任评估模型的研究

Research on Trust Assessment Model between Regions in Grid

在网格域划分的基础上,提出一种域间信任关系评估模型,具有同时兼顾服务的上下文和信任的时衰性的特点,并针对网格环境中的恶意节点和恶意推荐行为,给出相应的应对机制。实验表明,该模型能够有效地解决网格环境中的恶意行为,对恶意节点进行惩罚。

Proposes a trust assessment model between regions based on Grid region, which both considers context of service and the decline of trust. It also solves trust evaluation problems in Grid environment effectively by making the punishment system to malicious node and recommended action. By simulating experimentation, proves the practical, and which can settle down the trust issues in Grid environment efficiently.
