Data Security Access Control Model of Cloud Computing

The development of cloud computing are facing many challenges, one of the most concerning aspect is data security problem which resulted by the nature of its dynamic, sharing, openness and highly centralized mass data. From the perspective of the users, related research focused on the methods that ensuring the safety of data access and storage. This paper presents a control model of secured data accessing based on MAC access control, which origins from the experience of government cloud platform construction. This model provides the necessary technical and management strategies, in order to ensure the security of data accessing. Finally, the practical application test showed that the model with the corresponding control mechanism could meet the requirements for high reliability applications of government cloud.
