摘      要：To guarantee that electronic publications are accessible only to the authorized users via cloud, we propose an Efficient access control scheme(EACS) based on Attribute-based encryption(ABE), which is suitable for fine-grained access control. Compared with existing stateof-the-art schemes, EACS is more practical by following functions. Considering the factor that the user membership may change frequently, EACS has the capability of coping with dynamic membership efficiently. Arbitrary-State is also supported to facilitate the system management and improve efficiency. Besides, we prove in the standard model that the security of EACS is based on the Decisional Bilinear Diffie-Hellman assumption. To evaluate the practicality of EACS, we provide a detailed theoretical performance analysis and a simulation comparison with existing schemes. Both the theoretical analysis and the experimental results show that our proposal is efficient and practical for electronic publishing under cloud environment.
