abstract = "Key escrow and low efficiency are two practical bottlenecks of attribute-based encryption. In this paper, a Requester-Centric CP-ABE (RC-CP-ABE) combining removing escrow and outsourcing decryption is proposed. By the bilinear map of composite order, we optimized the computational complexity of key transformation in the case of a large number of attributes. Without adding roles in the system, data requesters can undertake the key transformation which make them the center in the interactive process and the bridge linking removing escrow with outsourcing decryption. Security analysis has been made to prove our algorithm secure.",
