The Trust Evaluation Mechanism Based on Multi-agent in Cloud Environment

Abstract

People do not take into account security issues at the beginning of the design of Cloud computing, thus it leads to a series of cloud security problems. This paper puts forward the trust evaluation mechanism in the cloud environment combining multi-agent and trust evaluation, using transaction weights as the trust factor to evaluate the trust value of cloud services. Experiments show that the result of trust evaluation agreed with the actual service behavior of cloud service, which can resist malicious attacks effectively, especially has a stronger robustness to the swing type attack of malicious cloud services.
