“…Hendricks et al express that this outcome can sidestep data pollution made by a couple parts in the cloud. On the other hand, Cachinet al declare that using the Byzantine blemish tolerant replication tradition inside the cloud is inadmissible in light of the way that the servers having a spot with cloud suppliers use the same structure foundations and are physically set in the same spot [1]. According to Garfinkel, another security danger that may happen with a cloud supplier, for instance, the Amazon cloud organization, is a hacked mystery key or data intrusion.…”

Data deduplication is a method for removing multiple copies of same data, and has been widely used in cloud storage to reduce storage space and uploading speed. However, there is only one copy for each file stored in cloud even if such a file is owned by a multiple number of users. As a result, deduplication system improves storage utilization while reducing reliability. Mostly, the challenge of privacy for sensitive data also arises when they are outsourced by users to cloud. Aiming to address the above security challenges, this paper makes the first attempt to formalize the notion of reliable deduplication system. We propose new distributed deduplication systems with higher reliability in which the data chunks are distributed across multiple cloud servers. The data confidentiality and tag consistency of data are also achieved by introducing a deterministic secret sharing scheme in distributed storage systems, instead of using convergent encryption as in previous deduplication systems. Security analysis depicts that our deduplication systems are secure in terms of the definitions specified in the proposed security model. As a proof of concept, we implement the proposed systems and demonstrate that the incurred overhead is very limited in realistic environments.

“…Ensuring the security of stored data is the most challenging issue in the cloud environments. This security has been divided to several parts and one of the most important parts is maintaining security in the servers of cloud computing service providers [2]. Therefore, applying a cryptographic method for authorized user is the most popular existing solutions for solving security issues and increasing the reliability of the cloud environments.…”

Abstract-Cloud computing is an emerging technology that is still unclear to many security problems. Ensuring the security ofstored data in cloud servers is one of the most challenging issues in such environments. Accordingly, this schema presents a Hybrid Encryption algorithm that is based on RSA Small-e and Efficient RSA (HE-RSA) for improving the reliability in cloud computing environments. The main aim of this project is to use the cryptography concepts in cloud computing communications and to increase the security of encrypted data in cloud servers with the least consumption of time and cost at the both of encryption and decryption processes.In the proposed model, the number of key generation exponents has been increased in comparison to the original RSA. Moreover,a dual encryption process has been applied in this algorithm to prevent common attacks against RSA algorithm. In addition, this schema also presents the comparison between HE-RSA and original RSA in terms of security and performance. For this purpose, Key Generation, Encryption and Decryption Time in Original RSA and HE-RSA have been compared according to the different size of exponents. Moreover, some of the common attacks against RSA algorithm have been analysed to detect the resistance of the proposed algorithm against possible attacks. Finally, the effects of using HE-RSA on cloud computing environments have been reviewed in more depth and details.

Summary Cloud computing has been an essential technology for providing on‐demand computing resources as a service on the Internet. Not only enterprises but also individuals can outsource their data to the cloud without worrying about purchase and maintenance cost. The cloud storage system, however, is not fully trustable. Cloud data integrity auditing is crucial for defending against the security threats of data in the untrusted multicloud environment. Storing multiple replicas is a commonly used strategy for the availability and reliability of critical data. In this paper, we summarize and analyze the state‐of‐the‐art multiple‐replica integrity auditing schemes in cloud data storage. We present the system model and security threats of outsourcing data to the cloud with classification of ongoing developments. We also summarize the existing data integrity auditing schemes for multicloud data storage. The important open issues and potential research directions are addressed.
