Research On Trustworthy Evaluation And Recommendation Method Of SaaS Service

Cloud Computing is an add-on,use,and interaction model for Internet-based services that can be billed based on user usage.Users can use all kinds of computing resources(including network,server,storage,application software,computing services,information services)provided by cloud computing with only a small amount of management work.With the development of cloud computing,various large Internet companies have launched their own cloud computing platforms to provide various cloud services in the form of their own or merchants.With the gradual development of the cloud service platform,the security issues related to cloud services are gradually emerging.Because users do not understand the implementation details and configuration of the cloud services they use,they generate trust issues related to cloud services,namely cloud services.Whether the provider can provide cloud services that meet its quality of service claims.In response to the above problems,this paper proposes a corresponding cloud service trust evaluation model.The main research contents are summarized as follows: 1.Analyze the malicious behaviors common to cloud service providers and cloud service users in existing cloud service platforms.According to the malicious behaviors of cloud service providers and cloud service users and the related requirements of system implementation,the cloud service trust evaluation model needs to be satisfied.Basic nature.2.In view of the failure to meet some of the basic nature of the existing research,the sliding window is introduced,and the slow growth window and the actual effective window are used to strengthen the process of cloud service trust evaluation in the existing research,and the cloud service trust evaluation based on sliding window is proposed.model.The code implementation of the evaluation and recommendation process in the cloud service trust evaluation model based on sliding window is provided,and the cloud service trust evaluation model in the existing research and the cloud service trust evaluation model based on the sliding window proposed in this paper are compared through simulation experiments.For common cloud service providers and user malicious behavior,the sliding window-based cloud service trust evaluation model can more accurately and quickly distinguish the credibility of cloud services.
