Abstract

The foremost security concerns for big data in the cloud are privacy and access control. Ciphertext-policy attribute based encryption (CP-ABE) is an effective cryptographic solution for above concerns, but the existing CP-ABE schemes are not suitable for big data in the cloud as they require huge computation time for encryption and decryption process. In this paper, we propose a new verifiable outsourced CP-ABE for big data privacy and access control in the cloud. Our scheme reduces the computational overhead of encryption and decryption by outsourcing the heavy computations to the proxy server. Our scheme also verifies the correctness of the data along with the outsourcing computations. Further, our scheme limits the data access for a set of users instead of providing an infinite number of times data access, which is essentially required for commercial applications. In security analysis, we prove that our scheme is secure against chosen plain-text attack, collusion and proxy attacks. Performance analysis proves that our scheme is efficient.
