Abstract
This paper describes the needs for trust models in grid environment, and analyzes the advantages and disadvantages of traditional grid trust models. A grid trust model based on the last service and hierarchy is presented, and the corresponding calculation formula is designed. Compared with the traditional grid trust model, the proposed model has such advantages as less resources occupied, low complexity of trust assessment and increased flexibility. Moreover, it can prevent the threat of malicious e-valuation and cooperative cheating in grid environment. Experimental results with the improved grid simulation tool GridSim indicate that the trust model enhances the reliability of the grid system.关键词
