网格环境中的一种信任模型

A Trust Model In Grid Environment

网格环境中的信任问题是当前网格研究的一个热点问题,为了解决网格环境的动态性和不确定性带来的安全问题,文章提出了一种新的信任模型来处理网格环境中实体之间的信任关系,该模型对域内信任关系和域间信任关系分别采取不同的方法进行处理,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。

Trust problem in grid environment is a hot topic in currently grid research.In order to resolve the security problems due to the dynamics and uncertainty of grid environment ,this paper develops a new trust model.It discriminates the trust relationships between entities in the same autonomous domain and in different domains,and handles the two different trust relationships with different approaches.By doing this,it can evaluate the trust relationships between entities more precisely,thus can resolve security problems existing in grid environment more effectively,which can be verified by simulated experiments.
