【摘要】Aiming at the problem of cloud users finding the appropriate cloud services which satisfy their performance preferences and special turst levels among a large number of cloud service providers, this paper proposed a behavior trust evaluation system of cloud services. First, it designed the trust evaluation system framework of cloud services, and established a trust evaluation model of cloud services based on membership theory. Next, it calculated the trust level of cloud services with the comprehensive trust cloud center of gravity evaluation( CCGE) method. Finally, the experiment results show that this model can build precise trust relationship between cloud users and cloud services based on users' performance demands.%针对云用户难以在大量性能特征不同的云服务提供者中找到满足自己性能偏好和特定信任等级的云服务的问题,建立了一个合理的、科学的云服务行为信任评估系统.设计了云服务行为信任评估系统框架,基于隶属度理论建立了云服务行为信任评估模型,利用综合信任云重心评价法来计算云服务行为信任度,经过实验分析,该模型能够根据用户性能需求,对云服务进行更准确、科学的信任评估. 【总页数】4页(1051-1054)
