Hierarchical Attribute Based Encryption. A user can delegate the private key corresponding to any subset of an attribute set while he has the private key corresponding to the attribute set. However its impossible to encrypt multiple files on the same access level in existing FH-CP-ABE scheme. Attribute-based encryption ABE has been envisioned as a promising cryptographic primitive for realizing secure and flexible access control. Fully Secure Functional Encryption.
