| 摘 要： | 提出了一种云计算环境中柔性易扩展的信任协商机制-基于相似信任度的信任协商机制,在该信任协商机制中,直接信任度计算过程中加入了为用户节点提供服务的服务时刻和服务成本等信任因素,间接信任度计算过程中加入了参与评价的云服务节点个数、评价用户节点的服务总量、评价用户节点所给评价的相似度等信任因素,并且详细讨论了这些信任因素的获取和计算方法.

| Abstract: | This paper proposes a flexible and easy-extensible trust negotiation mechanism based on trust similarity for cloud computing.In this mechanism,service time and service cost are taken into account in the process of calculating direct trust.While the calculation of indirect trust takes account of the number of cloud service nodes,total service amount of a service node,similarity of the evaluations given by different service nodes to a user node.Besides,we also discuss the gain and calculation of these factors... |
