The Research of Trusted Technology under Cloud Environment

In the current cloud environments, there are some problems of information in security and reliability. In order to establish more flexible and adaptable security mechanism, combining the cloud and credible is a major research direction in the field of security today. In this paper we studied some credible technology in cloud computing environment and a new reverse cloud generation algorithms is proposed. The expected value and hyper entropy of subjective cloud is used to evaluate the reputation of trust objects, and provide a basis for trust decisions online trading.
