Abstrakt:

Ciphertext policy attribute-based encryption(CPABE) is one of the efficient implementations of encrypt-ed access control scheme for cloud computing. Though multipleimplementations of CPABE exist, there are some issues that needto be addressed, including efficient revocation approach, de-cryption time, storage cost etc. In this paper, an efficient schemethat incorporates a hierarchical access structure, outsourceddecryption, as well as user and attribute revocation is presented.The hierarchical access structure is utilized to encrypt multipledata using one common access structure and makes the encryp-tion process more efficient. The outsourcing server is used toperform partial decryption, so that all heavy computations areperformed by this server and less overhead is incurred by thedata user. The proposed framework also integrates the evalua-tion of trustworthiness of data users and service providers toensure trusted and encrypted access control procedures. Thepaper also presents an analysis of the time required for per-forming different operations. Simulation results show that theproposed scheme outperforms the existing approaches.
