The traditional and Single Layer Encryption (SLE) approaches incur high communication and computational cost to manage key and encryption whenever user credentials change. So to overcome this problem, the Two Layer Encryption (TLE) process is proposed. In this paper, the TLE process solve that problem by using the access control enforcement responsibilities as possible to the cloud while minimizing the information revelation risks due to machinating users and cloud. Under this approach, the data owner performs the coarse-grained encryption and the cloud performs the fine grained encryption.
