In order to keep the confidential data in the cloud against unauthorized parties, a cryptographic access control solution based on Attribute-Based Encryption (ABE) and Identity-Based Signature (IBS) is introduced in this paper. Under the premise that cloud service provider is untrustful, the proposed scheme can ensure the data security of the cloud storage system in an open environment, as well as reduce the complexity of management. Analysis and experimental results show that the scheme can be semantically secure against adaptive chosen ciphertext attacks under the random oracle model. Our concrete access control scheme can enhance the efficiency of the cloud to a certain extent.
