Data sharing system such as social network or cloud computing there is an demand for distributed data security .The challenging issue in data sharing system is access policy and support of policy update cipher text .The policy attribute based encryption (CP-ABE)is cryptographic solution to this issue. The data owner defines their own access policy over user attribute and applies this policy on data. In this research work the proposed novel CP-ABE scheme is used to solve the key escrow problem by escrow free key issuing protocol generated by using two party computations between key generation center and data store center.
