摘　　要：安全性是网格计算系统研究的主要热点之一,在资源管理中结合信任机制能够有效地提高网格实体交互的可靠性。考虑到信任的不确定性,主要研究如何对信任概念进行量化,提出了一种基于网格系统的全局信任量化计算引擎,对其计算方法进行了重点讲述。通过实验与现有的信任计算引擎进行了比较,结果表明了该计算引擎的性能优势。Security is one major concern in grid computing system. Integrating trust mechanism into grid resource management can improve the reliability of grid entities＇ interoperation. Considering the uncertainty of trust, this paper mainly studies trust quantification, proposes a global trust quantification compute engine based on grid system and places an emphasis on compute method. Experimental results show that this method proposed is more robust on performance than the current trust compute engine.
