Abstract

ABE scheme has been more and more widely used in cloud storage, it can achieve fine-granularity access control. However, most of the existing ABE schemes have the problems of low efficiency and high overhead. In order to solve this problem, this paper proposed a more efficient and fine-grained attribute-based encryption scheme supporting attribute revocation. The transfers the complex computation of the encryption and decryption process to the proxy server, thus reducing the encryption and decryption computation of users. This paper also proposed an efficient attribute revocation method which concentrated on the update of the ciphertexts and users' secret keys associated with the corresponding revoked attributes, so the cost of attribute revocation is very small. And combined the method of two-factor identity authentication to improve the security of the algorithm. The theoretical analysis show that this scheme is safe under the standard model based on the DBDH hypothesis.
