摘　　要： 信任已成为网格安全的重要因素。信任一般具有模糊性,网格信任的模糊性是随时间和空间变化而变化的。本文基于动态和复杂的VOs信任域环境来研究解决网格系统的安全问题,设计了网格信任管理模式的安全体系结构,并提出了基于模糊逻辑的动态信任域作为安全的实施方案,以保证网格系统环境的安全性。 Trust has become an important factor of security in grid computing, generally, it is fuzzy and varies temporally and spatially. This paper firstly studied the fuzzy, dynamic and complex natures of trust in grid computing, then, proposed a good solution, dynamic VOs trust do- main, to grid security based on fuzzy logic theory, and finally designed a trust management architecture of grid security by incorporating a novel trust model, which is capable of capturing various types of trust relationships that exist in a Grid system and providing mechanisms for trust evaluation.
