| Abstract | Cloud computing have brought a lot of advantages, such as reducing the hardware cost and providing a convenient cloud storage service. More and more people choose to put their private data in the cloud. However, due to data outsourcing and seminal-trusted cloud servers, data access control has becoming a challenging issue. To protect data security and privacy, some ciphertext policy attribute-based encryption (CP-ABE) schemes have been applied to cloud data access control. However, there are two dynamic issues, namely attribute revocation and policy updating, that need to be solved in the existing CP-ABE schemes. In this paper, we propose a fine-grained dynamic multi-authority cloud data access control scheme, which can solve the above two problems. Besides, our scheme can also support user revocation, which make it more practical. The analysis and simulation results show that our scheme is secure in the random oracle model and is efficient. © 2019 IEEE. |
