Application-Oriented Remote Verification Trust Model in Cloud Computing

Abstract

The emergence and application of cloud computing can help users access to various computing resources and services more conveniently. However, it also brings forth many security challenges. This paper proposes the application oriented remote verification trust model, which is capable of adjusting the user's trust authorization verification contents according to the specific security requirements of different applications. The model also dynamically adjusts the user's trust value with the trust feedback mechanism to determine whether or not the requested resource or service should be provided, so as to guarantee the security of information resources. This paper provides a formal description of the basic components and trust properties of the model with a belief formula, and describes the framework for the implementation of the model.
