Evaluation of user behavior trust in cloud computing

Currently, the cloud computing is hot research both in scholars and enterprise, because of its good features such as low investment, easy maintenance, Flexibility and fast deployment, reliable service. But to truly implement cloud computing, we need to gradually improve it in academic, legal and institutional. Especially, the issue of trust is one of the biggest obstacles for the development of cloud computing. In the cloud computing, due to users directly use and operate the software and OS, and even basic programming environment and network infrastructure which provided by the cloud services providers, so the impact and destruction for 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. mainly discusses evaluation importance of user behavior trust and evaluation strategy, in the cloud computing, including trust object analysis, principle on evaluating user behavior trust, basic idea of evaluating user behavior trust, evaluation strategy of behavior trust for each access, and long access, which laid the theoretical foundation about trust for the practical cloud computing application.
