As an important part of security domain, access control technique is used to limit users’ capability and scope to access data and ensure the information resources not to be used and accessed illegally. This paper focuses on the state-of-the-art research of access control technology in cloud computing environment. First, it briefly introduces access control theory, and discusses the access control framework in cloud computing environment. Then, it thoroughly surveys the access control problems in cloud computing environment from three aspects including cloud access control model, cloud access control based on ABE (attribute-based encryption) cryptosystem, and multi-tenant and virtualization access control in cloud. In addition, it
