Cloud computing has emerged as a promising platform that grants users direct yet shared access to computing resources and services without worrying about the internal complex infrastructure. However, secure data storage and data retrieval is the basic characteristics. Therefore, this paper proposes a novel double keys adapted elliptic curve cryptography (DKECC) and log normalized Gaussian sigmoid adaptive neuro‐fuzzy interference system (LGS‐ANFIS) based secure resource allocation system in decentralized cloud storage. Initially, the input data undergoes data fragmentation. After that, encryption is carried out using DKECC algorithm. Next, hash code generation using Pearson hash function is done. Then, resource availability is estimated via logistic sine chaotic mapping indulged rock hyraxes swarm optimization technique. Afterwards, data is checked for deduplication. Finally, resource allocation through LGS‐ANFIS takes place. The experimental outcomes demonstrated better results compared to baseline techniques. The modelling process showed that the suggested safe resource allocation model achieves the total security level of 96.27% while also having shorter reaction times (3018 ms), greater throughputs (1258), reduced load balancing (0.355874), and reduced latency (4372 ms).

“…With the help of distributed hash tables, the TPA can perform data auditing in a better and efficient cost-effective manner and the data can be updated efficiently. [10] The security of this system has been evaluated and the comparisons of the auditing performance have been done. A scheme supports all the three problems of public auditing mentioned above i.e.…”

Today cloud computing has been the most popular service enjoyed by people due to the easy maintenance provided by it. Cloud computing is cost-efficient and people pay according to the services they use. Many organizations are using cloud storage and the reason behind it is that the outsourcing services are provided by the cloud computing. Most of people do not trust the legality of the services provided by cloud (CSPs i.e. cloud service providers) because they are afraid of the security breach of their data. The public auditing of the data by their owners is a technique that can maintain the trust of people on cloud services. This research paper is about cloud storage services based on the distributed hash table (DHT).This is required for dynamic auditing of information as this is new two-dimensional data and Third-party Auditor (TPA) is responsible for recording the information to do dynamic auditing and the dimensional data is located at TPA. The computational costs gets reduced when the authorized information is migrated to the two dimensional data and the Cloud service provider shifts it to the TPA DHT has many structural advantages and the services can be updated efficiently. The comparison with the present system is also made and is assured that it is the security system for the cloud storage. To secure the data information by blinding it, random masking is provided as a proof for securing process. The authentication is done via hashing technique and integrity and performance checks are made with this authentication process.

“…However, the above scheme cannot solve the problem of data redundancy well. To solve that problem, Wu et al [24] , Daniel and Vasanthi [25] removed redundant data from the cloud server which saved the storage cost of cloud service providers and greatly improved the efficiency of data validation. However, none of the above schemes have been designed specifically for images stored on the cloud, thus Tang et al [26] proposed an efficient real-time integrity auditing protocol specially designed for cloud images, which also supported fair arbitration.…”

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.
