Advanced Trust Based Approach For Increasing Security in Cloud Computing

Cloud computing has become one of the fastest growing fields in computer science. As the new computing service pattern of cloud computing develops rapidly, the security problem of cloud computing has become a hot research topic. Before the user passes important data or computing task to the cloud, the user of the cloud may want to verify the trusted status of the platform which actually carries out the computing task in the cloud. And the remote attestation mechanism in Trusted Computing is suited for the cloud user's verification need. Cloud computing basically provides people the way to share heterogeneous distributed resources and various services that belong to various organizations or sites. Since cloud computing share heterogeneous distributed resources via the network through in the open Internet Technology environment, thus it makes security problems necessary for us to develop the cloud computing application environment. In this paper, we pay attention to the security requirements in cloud computing environment system. We proposed a method to build a trusted computing environment for cloud computing system by integrating the trusted computing platform into the security of cloud computing system. We propose a model system in which cloud computing system is combined with trusted computing platform with trusted platform module. In this model, some important security services, including authentication, confidentiality and integrity, are provided in cloud computing system.
