Current approaches to enforce access control on privacy & confidentiality of data hosted in private cloud. Are based mostly on SLE under such approaches, data owners are in charge of encrypting data & decrypting it which involves huge burden in terms of computation & communication costs. A better approach is by taken key management. Thus minimizes load of data owner & ensuring more secured system. In this paper, they proposed a system which uses 2 layers of encryption & 2 layer of decryption for enhancing security & privacy using policy cover & policy decomposition algorithm along with AES in private cloud.
