Abstract:
This paper presents a trust model to evaluate the history behavior of entity. The model considers the number of transactions, the evaluation of other nodes and these nodes’ credibility. The simulation results demonstrate the model can precisely evaluate entity behavior, thus can efficiently resolve the safety problem of the entity behavior.

摘要： 提出了一种信任模型，对网格实体的历史行为进行评价、处理。该模型在进行评价的过程中综合考虑了网格实体的交易数量、其它节点的评价及其可信度。模拟实验结果表明该模型对实体行为的评价具有很高的准确率，因而可以解决实体行为的安全问题。
