Blockchain-based solutions for Cloud Computing Security: A Survey

Cloud computing is a technology that provides infrastructure and data services at an affordable cost, with minimal effort, and with a high level of scalability. And it is continuously increasing demands daily. Furthermore, it raised many security challenges that had to be addressed. Blockchain has become a critical technology for providing security, particularly regarding integrity, authenticity, and confidentiality. It also can help cloud computing growth by overcoming security challenges. Many blockchain-based solutions were proposed for security challenges in cloud computing. This survey gives a background about cloud computing and blockchain. Also, it briefly studies how blockchain can affect cloud computing, especially the security improvements it can provide. The main contribution of this paper is to explore and summarizes existing blockchain-based solutions for cloud computing security challenges.
