Hierarchical Attribute Based Encryption. We propose a hierarchical hierarchical user grant filecreation file deletion and attribute-set-based encryption HASBE scheme for access user revocation in cloud computing. The scheme is obviously not practical. File hierarchy attribute based encryption FH-CP-ABE is a scheme which both saves storage space of ciphertext and reduces the computation overhead of encryption. Ciphertext-policy hierarchical attribute based encryption.

T he computation cost in generation of ciphertext is low and the length of the ciphertext is short. Hierarchical attribute based encryption with continuous leakage-resilience 1. Attribute-Based Encryption and Hierarchical Inner Product Encryption - Fully Secure Functional Encryption. With system users having hierarchical structure to achieve flexible scalable and fine grained access control. Based on the HABE model we construct a HABE scheme by making a performance-expressivity tradeoff to achieve high perfor-mance. Moreover a resilientleakage hierarchical attributebased encryption scheme is.
In order to achieve scalable fine-grained and flexible access control for cloud computing we extends Ciphertext-Policy Attribute-Set-Based Encryption CP-ASBE by building in a hierarchical structure to obtain Hierarchical Attribute-Set-Based Encryption HASBE for cloud computing.

In this section we introduce some required preliminaries. First we propose a hierarchical attribute-based encryption scheme HABE by combining a hierarchical identity-based encryption HIBE system and a ciphertext-policy attribute-based encryption CP-ABE system so as to provide not only fine-grained access control but also full delegation and high performance. In order to achieve scalable fine-grained and flexible access control for cloud computing we extends Ciphertext-Policy Attribute-Set-Based Encryption CP-ASBE by building in a hierarchical structure to obtain Hierarchical Attribute-Set-Based Encryption HASBE for cloud computing. HASBE extends the cipher text- prove the security of the proposed scheme based on the policy attribute- set-based encryption CP-ASBE or ASBE.
