The Cloud Data Security and Access Control Model in the Study

Cloud computing is a kind of based on the calculation of the Internet, through the cloud computing, to other computers and other devices to share information and resources. Although it can bring convenience, operated and managed in a cloud computing infrastructure services in the security problem of nots allow to ignore. After the cloud security problem analysis, put forward the safety of the infrastructure services is the foundation of cloud computing security. Then, on the basis of the traditional access control model to take into consideration the characteristics of cloud computing infrastructure services, design a set of access control model. The model well enhanced the security of cloud computing infrastructure services. Cloud computing is a kind of new IT services based on Internet, use and delivery mode, cloud computing can through the Internet provides a variety of resources, dynamic easy extension and these resources can be virtualized. It means that the computing power can become a circulation of commodities in the Internet.
