  Abstract

When users store data in cloud service providers (CSPs), they lack full control over what happens to their data. CSP may unintentionally remove rarely accessed users’ data or encounter internal or external issues that compromise data integrity. To guarantee the integrity of users’ data stored in cloud storage, an auditing protocol is necessary. However, considering the massive amount of stored data, it is inefficient for the verifier to download all the data in advance. Subsequently, the verifier might not have proper resources and expose the user’s data privacy to other parties. Therefore, this paper proposes a blockchain-based data auditing protocol with a signcryption scheme in cloud storage. Smart contracts in a blockchain network are used to solve trust issues between the user, CSP, and the verifier. At the same time, the signcryption scheme is used to offer privacy-preserving during data transmission also, public verifiability, and blockless verification. The evaluation and security analysis show that the proposed protocol offers low computational and communication costs to do auditing tasks while offering desirable properties such as public verifiability, privacy-preserving, blockless verification, and reliable verifier.
