一种新的基于网格环境的行为信任模型

针对目前网格环境下资源管理和分配中所存在的安全问题,提出了一种新的基于实体行为的信任管理模型.着重描述了行为信任的定义和算法说明,实验和分析结果表明,与以往的信任模型相比,这种信任模型能更加精确地评估实体之间的信任关系,从而能更加有效地解决网格环境中存在的安全问题.

A NEW BEHAVIOR TRUST MODEL BASED ON GRID ENVIRONMENT

Aiming at solving the security problems of resource management and allocation in grid environment,a new trust model based on entities behavior is introduced,and an emphasis is placed on the conception and the algorithm of trust.Experiment shows that compared with other trust models,the new model can evaluate the relationships between entities more precisely,and resolve security problems existing in grid environment more effectively.
