Blockchain-based public auditing for big data in cloud storage

作者：

Highlights：

• The proposed scheme provides more secure and reliable public auditing services for cloud storage.

• In the scheme, only two entities (Cloud Service Provider and Data Owners) are involved, and blockchain technique instead of a Third Party Auditor is utilized to provide a better auditing service.

• A security analysis is provided, and the network performance simulation is conducted on our scheme and others.

• Our scheme outperforms others in terms of security and overheads on computation, communication and storage.
