Towards virtuous cloud data storage using access policy hiding in ciphertext policy attribute-based encryption

Managing and controlling access to the tremendous data in Cloud storage is very challenging. Due to various entities engaged in the Cloud environment, there is a high possibility of data tampering. Cloud encryption is being employed to control data access while securing Cloud data. The encrypted dat...
