With the development of cloud computing, it provides more and more important services over the internet. However, it brings also some new challenges for data security and access control when people put their sensitive data on cloud servers. In this paper we propose a access control model to achieve fine-grainedness, data confidentiality, and scalability simultaneously by exploiting CP-ABE (Bethencourt, Sahai, and Waters, 2007) and uniquely combining it with techniques of user hierarchy and attribute hierarchy. Also the formal definition of the HABAC model is presented in the paper.
