The secured data sharing is provided between the data owner and user based on the user’s attributes. It achieves more secure and fine grained data access control in the data sharing system. Data security is the key concern in the distributed system. Cryptographic methods are used to enforce the access policies of users. But here the key generation center (escrow) can obtain the messages sending between the users by generating the private key. This is referred as Key escrow problem. This problem can be solved by escrow free key generation using 3PC (Three Party Computation). Thus the proposed system gives the greater performance and security to the distributed data sharing system.
