英文摘要	In order to enhance the privacy preserving mechanism of cloud storage scheme and promote the cloud storage system in the enterprise, we propose a cloud storage scheme with multiple encryptions. The scheme adopts hybrid cloud structure and supports the direct revocation of users. The private cloud provided by the enterprise not only protects the attribute privacy in the access policy but achieves the pre-decryption mechanism reducing the decryption overhead for users. We introduce the identity authentication mechanism in the scheme and protect the users’ identity though the homomorphic encryption over integers. Based on the Decisional Linear assumption and the integer approximate Greatest Common Divisor problem, the proposed scheme is secure in the random oracle model. The analysis shows that our scheme is more secure and practical. © 2019, Springer Nature Singapore Pte Ltd.
