Research Of Behavior Trust Model In Cloud Computing Environment

With IT technology rapid development, cloud computing has become one of hottest research techniques. It is a business model, computing tasks will be distributed in the resource pool consisting of a large number of computers that allows users to demand obtain computing power, storage space and information services, and free the user from the complexities of the underlying hardware logic, software stack, and network protocol. At the same time the world's major IT companies have launched their own cloud computing services, major universities and research institutions will also be on cloud computing in the scope of their research. It is because of this cloud type of service, so people are optimistic about its development prospects to vigorously pushed forward the development and popularization of the technology.With the promotion of universal cloud computing applications, through the cloud computing platform in the computer, the privacy of any personal information and the company's core data are likely to access the Internet at any terminal device was found, in order to more extensive cloud Application, then the safety issue has become a top priority had to be resolved. The issue of trust in security issues is a popular cloud computing one of several major barriers that users can not trust the cloud service provider, whether the cloud service provider can provide a trusted environment or not, In short is that at the cloud computing Environment, whether end users and cloud service providers can trust each other or not. Based on the above issues in this article, we propose a Research of Behavior Trust Model in Cloud Computing Environment, the main Core work in the following areas:0First, we in-depth research and analysis the basic issue of trust of cloud computing, Combined with the characteristics of cloud computing, in the cloud computing environment the trust is divided into acts trust and identity trust, trust is assumed to confirm the identity of the case, for cloud service providers and users of behavior trust on the environment in the cloud being a detailed interpretation and induction, Studied the behavior of the trust value is calculated, and build a cloud computing environment behavior trust model.Second, the paper propose trust model, including user's behavior trust assessment and behavior trust of cloud service providers evaluation. Because the trust has its subjectivity, fuzziness and other characteristics, in order to protect the objectivity, impartiality, fairness, the paper's issue of trust based on the previous research proposed the trust assessment based on third-party cloud service providers-Cloud Commerce. The model also used the network analysis method (Analytic Network Process, ANP) was established cloud service provider and users corresponding ANP model that can be calculated weight of relative sub-evidence the evidence, and then influence their own behavior Sub-trust behavior (this is called sub-evidence) were classified and screening, summarizes the existing technology and means to detect the basis of their values, and were normalized. used of the sub-values and relative Weight can be calculated trust value, and presented based on the trust value of the sliding window update and treatment. Finally, the simulation experiments to verify the feasibility and effectiveness of the model.
