“…Now, we analyze the probability that B can guess the correct query of the target data block by simulating operation. Similar to the analysis and proof of [48,50], B only halts two queries on partial key query and tag query; therefore the probability of B implementing the queries is higher than (1 − c) q p +q T . Assume that the probability of occurrence of output of the right value of g ab for B is ε…”

The pandemic of COVID-19 has posed a severe challenge to the traditional on-site centralized development projects; people therefore have to share data in a group by the cloud storage server and develop projects at home. The cloud server is untrustworthy, although it supplies the powerful computing capability and abundant storage space; so far wide research has been proposed to verify data integrity. Therefore, how to leverage the cloud server and ensure the integrity of the data (especially the encrypted data) stored on the remote cloud devices remains an issue for the clients. To address this issue, we utilize the technique of homomorphic hash function to implement reencryption ciphertext blocks and introduce a certificateless signature scheme for the integrity verification of encrypted data shared within a group. A detailed challenge-and-response game represents that the proposed scheme can preserve encrypted data blocks integrity against the internal/external attacker and malicious cloud service servers. We give the theoretical and experimental performance analysis of the scheme and exhibit that the scheme is efficient and practical.

The cloud is the best method used for the utilization and organization of data. The cloud provides many resources for us via the internet. There are many technologies used in cloud computing systems; each one uses a different kind of protocols and methods. Many tasks can execute on different servers per second, which cannot execute on their computer. The most popular technologies used in the cloud system are Hadoop, Dryad, and another map reducing framework. Also, there are many tools used to optimize the performance of the cloud system, such as Cap3, HEP, and Cloudburst. This paper reviews in detail the cloud computing system, its used technologies, and the best technologies used with it according to multiple factors and criteria such as the procedure cost, speed cons and pros. Moreover, A comprehensive comparison of the tools used for the utilization of cloud computing systems is presented.

“…Based on this, Wang et al [18] proposed a relatively complete protocol which can support data update, user privacy protection, and batch auditing, but it will lead to the problem of high computing cost on the client side. Then, Garg et al [19] designed a protocol that can minimize the computational complexity for the client during the system setup phase, which is publicly verifiable and supports dynamic operations on data.…”

Aim: With the popularity of cloud storage, data integrity has become a hot research spot. As clients' data is outsourced to the cloud, how to prevent clients' privacy from being leaked has become an urgent problem to be solved. In addition, the design of the storage structure in the cloud is also a challenge. To solve the above problem, we focus on enabling data integrity verification in the medical environment with clients' privacy protection and a novel storage structure assisted. Methods: By leveraging the one-way anonymous key agreement and the novel stereo storage structure, a novel stereo storage structure assisted one-way anonymous auditing protocol in e-health system is proposed. First, the one-way anonymous auditing protocol can realize the adaptive anonymity of clients in the e-health system. Second, the novel stereo storage structure can implement the storage and fast search of medical data. Results: The theoretical analyses indicate that the proposed scheme is secure under the Computational Diffie-Hellman problem and Discrete algorithm problem and it has a decent performance in computational overhead. Besides, the simulation results demonstrate that the computational cost of the user is constant. Conclusion: To protect the user's private information in e-health system, we propose a stereo storage structure assisted one-way anonymous auditing protocol in this paper. In the proposed scheme, fast searching of data, the one-way anonymity and the data auditing with mutual supervision are supported, which is necessary for the patients and the medical personnel in a real e-health scenario.
