Research And Design Of Trust Measuring Model Based On Cloud Computing

With the development of cloud computing, cloud services have been used in a wide variety of industries. More and more cloud service users give their data and computing tasks to cloud server to reduce computing and storage overhead. However, this caused cloud users to lose control of their data and computing tasks. The users start to seriously doubt whether the cloud environment is trusted or not. Thus the trustworthy issue of cloud service becomes the major factor that affects the development of cloud computing.There are few issues involved in cloud environment. The first and most important one is the trustworthiness of cloud infrastructure. The traditional chain-of-trust model is compatible with PC architecture, but to place it in the cloud environment, there are still lots of practical issues. Especially, the trust measuring model of cloud service must consider the concurrency, safeness, and expandability needs of servers and virtual machines.Starting from the above perspective, this article first gives an introduction of the current research of cloud computing and trusted computing technology, analyzes the research conclusions of trusted computing related to cloud computing. Second, it researches and deeply analyzes the traditional trust measuring model and mechanisms. Finally it introduces trusted computing technology that accommodates cloud environment features. This article proposes a hierarchical based and multi-target fused trust measuring model that can be used in cloud environment, to guarantee that cloud infrastructure is trustworthy. This article provides meaningful research of cloud environment trust measuring model, analyzes and describes the design of trust measuring model in great detail. It’s very valuable both theoretically and practically.
