“…In proof verification, the scheme [25,47] needs two pairing operations and the scheme [49] needs three paring operations, but in the scheme [48], the paring operation is linear with the number of challenged blocks, while our scheme and the scheme [48] reduces (c + 1) multiplication operation and two exponentiation operations compared with the scheme [47,49]. Although [24] outperforms other schemes in terms of exponentiation and paring operations, it does increase linearly in terms of multiplication operations. Nonetheless, the above schemes all make various computational concessions for functionality while satisfying their proposed functional properties on the basis of security.…”

“…To reduce the computational burden on the user side, public auditing schemes [8,[10][11][12][21][22][23] are proposed to allow TPAs to audit the integrity of their cloud data on behalf of data owners. To guarantee the integrity of medical data and reduce the burden of the data owner, Li et al [24] propose an efficient, privacy-preserving public auditing protocol for cloud-based medical storage systems that supports the functions of batch auditing and dynamic update of data. is scheme not only saves TPA and data owner computation costs but also reduces the communication overhead between TPA and cloud servers.…”

The data outsourcing services provided by cloud storage have greatly reduced the headache of data management for users, but the issue of remote data integrity poses further security concerns and computing burdens. The introduction of a third-party auditor (TPA) frees data owners from the auditing burden and alleviates disputes over the audit results between data owners and cloud storage providers. However, malicious cloud servers may collude with TPAs to deceive users for financial profits. Hiring multiple auditors in a single audit assignment appears to be a method to address the above problem, but the ensuing voting issues need to be further explored. In this paper, we proposed a smart contract-based outsourced data integrity auditing scheme for multiauditor scenarios. Unlike some existing schemes using reputation like factors as their voting weights, auditors in our scheme vote equally and audit as they go, without any maintenance. This mechanism not only frees auditors from trivia not related to the auditing but also avoids the drawbacks of centralization associated with over-high voting weights. The challenge used to check the integrity of the outsourced data is jointly generated by each involved auditor. Any collusion would be detected as long as there exists more than one honest auditor in the audit. We implement and deploy the scheme as Ethereum smart contracts. With the help of blockchain, the entire auditing process is public and transparent. Both the generated data and the obtained results are persisted with immutability, which ensures the traceability of all historical audits. The comprehensive theoretical and experimental analyses demonstrate that our scheme meets the claimed targets with high efficiency and low gas costs.

Cloud‐based medical storage system is becoming popular. Cloud server is curious about the private information of stored cases, and the integrity of outsourced data has become increasingly concerned. Numerous public auditing protocols for the outsourced data into the cloud server were proposed. Unfortunately, in the existing protocols, some of them may neglect security to improve efficiency. Recently, Li et al. proposed an efficient privacy‐preserving public auditing protocol for cloud‐based medical storage system (EPPAP), which improved the communication efficiency by storing some of data owner's data in third part auditors, however we find that the protocol is vulnerable to collusion attack and replace attack. In this paper, we analyze the security attacks of the existing protocol, and further propose an improved public auditing protocol for secure data storage in cloud‐based medical storage system (IPAPS). In addition, we give the formal security proof and analyze the performance of our proposed protocol. The security proof shows our protocol takes into account integrity, collusion attack and replace attack at the same time. The simulation experiments in our performance analysis show that the proposed protocol is practical.
