FOG computing enhances communication efficiency by processing data at the network's edge. In many critical infrastructure (CI) networks, user entities outsource data to the FOG server, but the reliability of the data is a concern. To avoid incorrect decision-making due to corrupt data, a data auditing process is mandatory. Further, a group of user entities in a CI network generate data onto a common file and outsource the file to the FOG server. Auditing such shared group data creates additional complexities. Existing shared group data auditing schemes using public key infrastructure (PKI) or identity-based cryptography (IBC) face challenges such as certificate management or key escrow problems respectively. While, certificateless cryptography (CLC) offers better security and efficiency, but many CLC-based shared group data auditing schemes lack protection against key generation center compromise. The key generation process in many of the existing shared group data auditing schemes is centralized and does not support flexible user entity admission. This paper proposes a distributed and decentralized cryptography approach to enhance the security of key generation for group members. The scheme offers flexible user admission, allowing for full or semi-membership. The proposed scheme provides efficient and secure shared group data auditing against public key replacement, metadata forgery, and integrity attacks, as shown by performance evaluation and security analysis.

“…Han et al [21] noticed the risk brought by untrusted TPA, but they made a mistake in the smart contract design that allowed CSP to perform replay attacks. Yuan et al [22] introduced identity-based cryptography into blockchain-based PDP scheme, to avoid the complex certificate management caused by the public key infrastructure. Li et al [23] tried to add cryptocurrencies to PDP scheme to promote TPA to be more active.…”

Cloud storage has been widely used to team work or cooperation development. Data owners set up groups, generating and uploading their data to cloud storage, while other users in the groups download and make use of it, which is called group data sharing. As all kinds of cloud service, data group sharing also suffers from hardware/software failures and human errors. Provable Data Possession (PDP) schemes are proposed to check the integrity of data stored in cloud without downloading. However, there are still some unmet needs lying in auditing group shared data. Researchers propose four issues necessary for a secure group shared data auditing: public verification, identity privacy, collusion attack resistance and traceability. However, none of the published work has succeeded in achieving all of these properties so far. In this paper, we propose a novel blockchain-based ring signature PDP scheme for group shared data, with an instance deployed on a cloud server. We design a linkable ring signature method called Linkable Homomorphic Authenticable Ring Signature (LHARS) to implement public anonymous auditing for group data. We also build smart contracts to resist collusion attack in group auditing. The security analysis and performance evaluation prove that our scheme is both secure and efficient.

“…Blockchain is a decentralized new distributed computing paradigm. Applying blockchain technology to cloud computing [25][26][27], using the security mechanism of blockchain to improve the secure storage and computing performance of the cloud is a good research topic. Hao [28] et al proposed a blockchain-based outsourced data integrity verification scheme in a non-trust environment.…”

Data Integrity Audit Scheme Based on Quad Merkle Tree and Blockchain

Cloud storage is an essential method for data storage. Verifying the integrity of data in the cloud is critical for the client. Traditional cloud storage approaches rely on third-party auditors (TPAs) to accomplish auditing tasks. However, third-party auditors are often not trusted. To eliminate over-reliance on third-party auditors, this paper designs a blockchain-based auditing scheme that uses blockchain instead of third-party auditors to ensure the reliability of data auditing. Meanwhile, our scheme is based on the audit method of the quad Merkle hash tree, using the root of the quad Merkle hash tree to verify the integrity of data, which significantly improves computing and storage efficiency. Automated verification of auditing activities by deploying smart contracts on the blockchain allows us to have a more up-to-date picture of data integrity. The performance of the scheme is evaluated through security analysis and experiments, which prove that the proposed scheme is secure and effective.INDEX TERMS Integrity auditing, Blockchain, Merkle tree, Smart contract.
