In this paper, the authors present a scheme achieves scalability and also inherits flexibility and fine-grained access control in supporting compound attributes of ASBE. In the other hand HASBE implement multiple value assignments for access expiration time to deal with user revocation more efficiently than existing schemes. Later, they prove the security of HASBE based on the Cipher text-Policy Attribute-Based Encryption (CP-ABE) scheme by the researcher and analyze its performance and computational complexity. They implement their scheme and show that it is both efficient and flexible in dealing with access control for outsourced data in cloud computing with comprehensive experiments.
