A novel approach to providing secure data storage using multi cloud computing

Abstract

The cloud computing is a new technology that has been presented in the market un recent years. However, it suffered several security breaches, and has some open issues, in terms of security. Due to that, the literature was investigated to highlight the cloud computing security issues, it was found that about 50% of cloud computing security issues are associated with data storage, applied cryptography, and applied authentication. On the other hand, multiple-cloud paradigms have been developed as efficient solutions in order to overcome some single cloud paradigm obstacles and limitations, and enhance the efficiency of ICT cloud-based solutions. Developing an approach that is stable and capable of delivering a very high level security and availability cannot be achieved by relying on a high layer of the delivered system (the software), the lower layer (the infrastructure) must be involved in order to achieve that level of service. This study aims to improve the security of the delivered cloud storage service via multiple-cloud computing and to develop an approach for providing a secure data storage system that could be installed, configured, and easily consumed through the appropriate multiple-cloud model. The developed approached is supposed to maintain the confidentiality, integrity, and authenticity of the protected data; besides that, it will support disaster recovery and auditing for the system. This study aims to reduce the complexity and required knowledge levels associated with consuming a multiple-cloud computing paradigm and enhance the flexibility. In order to validate and verify the developed approach, a prototype was developed and tested, the testing phase consists of three core experiments, the outcomes of these three experiments were analysed, presented, and discussed. From the collected feedback, we could conclude that the developed prototype performance is as expected and developed prototype has been validated and verified.
