| 摘 要： | 针对网格环境的动态性和不确定性带来的安全问题,提出了一种以域为单位改进的信任模型。该模型对域内信任关系和域间信任关系分别采取不同的策略进行处理,充分考虑了网格的特点及时间衰减等因素,并从信任表达、提高信任准确度方面改进了模型,同时给出信任计算模型的信任值更新函数。模拟仿真实验及结果分析表明,这种信任模型能更加精确地评估实体之间的信任关系。

| Abstract: | This paper resolve the security problems due to the dynamics and uncertainty of grid environment,it proposes an improved trust model based on domain,which discriminates the trust relationships between entities in the same autonomous domain and in different domains,and handles the two relationships with different approaches.It takes into account the characteristics of grid and time-attenuation factor,and discusses the expression of trust-calculation,and gives the updating function with trust value.It can res... |
