The Sliding Window Method: An Environment To Evaluate User Behavior Trust In Cloud Technology

Abstract: Trust is one of the most concerned obstacles for the adoption and growth of cloud computing. Although several solutions have been proposed recently in managing trust feedbacks in cloud enviornemts, how to determine the credibility of trust feedback in a cloud environments is difficult problem due to unpredictable numbers of cloud services consumers and highly dynamic nature of cloud environments. In the cloud computing, due to users directly use and operate the software and OS, and even the basic programming environment and network infrastructure which provided by the cloud service providers, so the impact and destruction of the software and hardware cloud resources in cloud computing are worse than the current Internet users who use it to share resources. Therefore, that whether user behavior is trusted, how to evaluate user behavior trust is an important research content in cloud computing. In this paper we mainly discusses evaluation importance of user behavior trust and evaluation strategy, in the cloud computing, including trust object analysis, principle in evaluating user behavior trust, the basic idea of evaluating user behavior trust, evaluation strategy of behavior trust for each access, and long acsess. In trust evaluation, behavior evidence is the fundamental basis of behavior evaluation. But at present, researchers almost directly use node behavior results or use a third party’s evaluation results to synthesize it, not study the original evidence of node behavior and ignore an analysis of node behavior history, which limit the reliability, rationality and sharing of trust. Drawing on the characteristics of social trust and trust requirement, we first put forward basic criteria about evaluating node behavior trust, and then bring forward a kind of evaluation mechanism on node behavior trust based on sliding window model.
