Attribute-Based Encryption Scheme solves the security problems faced by cloud storage. In many practical applications, the files encrypted by Attribute-Based Encryption have the characteristics of multiple levels. However, CPABE cannot encrypt the data according to the level. This paper proposes a hierarchy attribute-based encryption algorithm to support the direct revocation. First, the encryption process of algorithm is introduced, second, the model of hierarchy attribute-based encryption algorithm is proposed to support the direct revocation, and the security proof of the algorithm is also given. Finally, we design two experiments to compare the proposed algorithm with existing algorithms from the perspective of time.
