摘　　要：为了给协同制造网格节点之间的资源访问和共享的交互行为提供信任度量,提出一种制造网格环境下基于节点行为信任的访问控制模型。将制造网格节点的关系划分为管理域内信任关系和管理域间信任关系,给出制造网格节点之间交互行为的信任关系描述和定义,以及节点间交互行为的信任度公式表达和计算方法,通过计算将制造网格中节点交互的信任情况反映到交互行为中。实验结果表明,该模型在一定程度上可有效用于解决制造网格环境中自私节点的动态性和不确定性带来的安全问题。In order to provide trust measurement for resource access and the shared interactive be- haviors of manufacturing grid nodes, an access control model based on nodes trust in manufacturing grid environment is proposed. This model divides trust relationship between grid nodes into trust re- lation domain and trust relation outside domain, and gives out their expressions and definitions. Methods to calculate direct trust value and recommendation trust value are presented. These trust measures between manufacturing grid nodes calculated by trust formal can reflect to interactive be- haviors. According to the simulation results, this model is effective for node＇s trust relation manage- ment within manufacturing grid, and can solve some security problems brought by node＇s, dynamics and non-determinacy in manufacturing grid environment to a certain extent.
