Abstract
Attribute-based encryption (ABE) is a promising technology to provide fine-grained access control for the encrypted data and hence is widely used in the outsourced storage. However, it can not support the secure deduplication for its encryption feature. In order to handle this problem that users with different access policy to the ciphertext of the same plaintext should retrieve this ciphertext normally, we propose a novel ABE scheme supporting fine-grained authorized secure deduplication. Compared with the related works, we consider the dynamic policy update which adapts to the real-world environment more.
