Research on Data Security Access Control Mechanism in Cloud Computing Environment

Abstract

Cloud computing is an Internet-based virtualization application model that has been in development for these years. Cloud computing technology provides users with a large number of virtualized computing and storage resources. As a continuously developing emerging technology, some theoretical and technical systems have been formed in countries all over the world. However, the data security in the virtualization environment of cloud service providers has attracted extensive attentions of users over the years. In the cloud computing environment, data access control mainly includes two aspects: one is the safe transmission of required information resources in the network, and the other is the reasonable control of user permissions. In this paper, we analyze the cloud computing platform based on OpenStack and the related data security access control model is proposed. The data access control process is studied where trust of the cloud user is evaluated. An access control system based on the studied model is then designed whose architecture and its components are described. The proposed model and system is expected to provide a new technical method for data security protection so as to lower the risks of data leakage.
