Abstract:

Considering the ambiguity, complexity, and uncertainty of subjective trust and considering the demand on grid resources, we propose a grid reputation resources selection model based on multi-service attribute by analyzing the trust management in the process of grid resources access, learning from human society, and introducing the concept of service attribute. The service requester will comprehensively evaluate the service attribute based on their preferences to select transaction object. After the transaction, the service requester judges the credibility of service provider based on the actual quality of service and then measures the credibility. Simulation results show that the model can withstand attacks of malicious entities and raise the success rate of resource selection.

Key words: grid system, reputation model, resource selection, quality of service
