针对目前云计算平台有可能被恶意利用及云服务提供商不被信任的问题,迫切地需要建立一个客观、有效的方法来评估云服务是否可信.已有的研究缺乏完善的云计算可信性测评框架和质量模型.基于典型的云服务应用,研究云平台可信性的指标体系,通过对可信性质量属性建模,建立云服务可信性量化评估模型,从而指导云服务可信性评估方法的建立.最后,给出了模型分析和应用模式,验证了所提出的模型的有效性. 相似文献

信任管理模型是物联网可信性评估问题的潜在解决方案,目前关于物联网信任模型的研究主要集中在定性分析和无线传感器网络上,可操作的定量分析成果很少。本文主要研究了在物联网分层架构下,智能物品追踪场景下的可信建模问题。从信任的建立、信任的建模、信任的计算、信任的传递、信任的决策5个典型的信任管理生命周期依次量化建模,建立物联网的量化信任管理模型。仿真结果表明所提模型相对于以往信任模型具有更好的鲁棒性和任务执行效率。 相似文献

Trust management has been proven to be a useful technology for providing security service and as a consequence has been used in many applications such as P2P,Grid,ad hoc network and so on.However,few researches about trust mechanism for Internet of Things(IoT) could be found in the literature,though we argue that considerable necessity is held for applying trust mechanism to IoT.In this paper,we establish a formal trust management control mechanism based on architecture modeling of IoT.We decompose the IoT into three layers,which are sensor layer,core layer and application layer,from aspects of network composition of IoT.Each layer is controlled by trust management for special purpose:self-organized,affective routing and multi-service respectively.And the final decision-making is performed by service requester according to the collected trust information as well as requester' policy.Finally,we use a formal semantics-based and fuzzy set theory to realize all above trust mechanism,the result of which provides a general framework for the development of trust models of IoT. 相似文献
