摘要

Cloud computing (CC) is a distributed and centralized network of interconnected and interrelated systems that has emerged asan area of incredible impact, potential, and growth in the IT domain. In the last few years, this paradigm has thrived to becomethe fastest evolutionary segment for business and various industries. Despite the many advantages provided by the cloud,serious challenges related to privacy and security have arisen such as privacy exposure, data loss, manipulation, service-levelagreement (SLA) violation, and concerns over the service and deployment models. In this article, a blockchain-based hybridalgorithm is proposed to tackle the privacy inefficiency of existing tools. A novel hybrid technique is used to encrypt dataahead of outsourcing it to data centers, and a unique digital signature is generated at clients and stored on a decentralized setof blocks. A virtual cloud similar to actual cloud service infrastructure was built to test the proposed framework. Despite theadditional computational powers needed to run the proposed framework due to blockchain integration, the results show thatdata integrity and reliability are preserved and user’s privacy is increased. Our results are discussed and benchmarked againstthe standard privacy tests standards such as changes in the stored data, the negligible overheads on cloud performance, andthe data records of the blockchain structure.
