| 摘 要： | 信任管理是网格安全研究的核心内容,根据网格的特点,提出了一种信任模型;模型中把网格实体之间的信任关系分为域内信任关系和域间信任关系,并给出了相应的定义和参数,信任度的计算和更新过程;引入时间衰减函数,使信任值的计算更加精确;仿真表明,该模型可以保证推荐信任值的可靠性,防止联合欺骗,有效地解决了网格环境中的信任评估问题。

| Abstract: | Trust management is the central part of grid security research.From character of grid,a trust evaluation model is put forth.The trust model includes same domain trust relationship and different domains trust relationship,the corresponding definition and the parameter,and the computation and renewal of the trust value.The trust value is more precision by presented the factor of time-attenuation.The results of simulation experiments show that the model ensures the reliability of the recommend trust and preven... |
