Secure and Efficient Data Integrity Verification Scheme for Cloud Data Storage

Cloud computing is a computing facility which allows its clients to outsource their information on distant cloud based servers without having the pressure of maintaining it. Of several remote data storage issues, data integrity preservation problem has gained much attention of researchers all over the world. Numerous research work has been done by researchers all over the world in the field of data integrity audit in cloud computing. Proposed work is an efficient and stable data integrity verification scheme based on Schnorr signatures. In Schnorr signatures, the signature verification equation is linear and also batch verification of several blocks is possible. Most existing schemes are based on Boneh Lynn and Shacham (BLS) and RSA signature schemes. However, in contrast with existing schemes, the proposed scheme is highly efficient and safe and pays lower verification computation costs proven experimentally in this paper.
