“…For example, outsourcing stored data at the cloud requires an additional security layer to strengthen the data confidentiality. Research [51] introduced a ''cloud storage based on ID-based encryption'' (CS-IBE) with the one file access policy and a user's identity proposed to be used as an encryption key. Although this approach simplifies the key management issues, it shows limited performance for data confidentiality.…”

Cloud computing has become a widely exploited research area in academia and industry. Cloud computing benefits both cloud services providers (CSPs) and consumers. The security challenges associated with cloud computing have been widely studied in the literature. This systematic literature review (SLR) is aimed to review the existing research studies on cloud computing security, threats, and challenges. This SLR examined the research studies published between 2010 and 2020 within the popular digital libraries. We selected 80 papers after a meticulous screening of published works to answer the proposed research questions. The outcomes of this SLR reported seven major security threats to cloud computing services. The results showed that data tampering and leakage were among the highly discussed topics in the chosen literature. Other identified security risks were associated with the data intrusion and data storage in the cloud computing environment. This SLR's results also indicated that consumers' data outsourcing remains a challenge for both CSPs and cloud users. Our survey paper identified the blockchain as a partnering technology to alleviate security concerns. The SLR findings reveal some suggestions to be carried out in future works to bring data confidentiality, data integrity, and availability.

“…One of the rising techniques for tending to this problem is cryptography. Bentajer et al [12] presented the ID-based encryption design, i.e., CS-IBE, for using public cloud storage that targets to secure the confidentiality of sensitive information. According to CS-IBE, configuration files are associated with single file accession practice with the client ID which will be utilized as the key to encipher.…”

Lifeblood of every organization is its confidential information. The accentuation on cybersecurity has expanded considerably in the course of the last few years because of the expanded number in attacks at the individual and organization and even at the state level. One specific zone of consideration is the assurance of the security of nuclear information. This may relate to both Instrumentation and Control (I&C) and Information Technology (IT). The present security measures are insufficient for nuclear information because of their lack of identification, classification, and securing measures (because of their multifaceted nature). With the increasing trends of data storage and management with the assistance of cloud, data confidentiality threats are immensely increasing. As there is no such safeguard that can make our systems a hundred percent secure, the best approach is to provide security at distinct layers. The basic purpose of layered security is to have the benefit that if one layer fails or compromised, the other layer compensates or maintains that confidentiality with the access control in the owner’s hand. In this paper, we have proposed a multilevel approach with protection-based computing by using Modular Encryption Standard (MES). We proposed a cloud framework as well to further enhance its security by utilizing a multicloud and modular approach. By performing simulations, the obtained results depicted that our proposed scheme works efficiently than other commonly used schemes.

“…The main concerns are about confidentiality, integrity and privacy of the outsourced data [2,3] CSPs are leveraging cryptography as lever for mitigating security concerns in order to strength confidence of end users on their services. Cryptography can be involved in two major levels of security, namely secure storage [11,[4][5][6][7] and secure gain provided by the solution. The lack of detailed technical information about the solution and about the span of its adoption by final cloud users make the final statement very difficult.…”

The aim of this paper is to propose a model to strengthen the security of key management in cloud computing, where the model is shared or entirely controlled by a non-trusted third party provider. Key management is not a straightforward matter for IT-teams, in addition to critical issues related to properly managing and securing the keys on providers’ infrastructures, they have to deal with concerns specific to multi-cloud key management. Hardware Security Module (HSM) solution that offers a secure on-premise encryption key management turned out be impracticable for widespread cloud deployment. HSM as a Service seems to be the best approach for key management in multi-cloud, but the service is wholly owned and managed by another cloud provider. In This paper, we present an efficient and secure cloud key management that fulfills the requirements of multi-cloud deployment. The proposed design splits the key into a blinded version of n shares that will be stored in encrypted format at the cloud provider side. To demonstrate the efficiency of the proposed design, we implement a fully featured prototype and evaluate its performance. Results analysis shows that the proposed design is highly efficient and can serve as a groundwork for using secret share as a way to protect keys in a multi-cloud environment.
