Multilevel Security Framework based on An Onion Encryption in Public Cloud Network

Cloud computing has evolved as a well-known technology in the twenty-first century for delivering data service requirements at a low cost, with minimal effort, and with a high level of scalability. Because the Public Cloud has some passiveness, hackers can effortlessly get unauthorized admittance to data, launch fabrication attacks, and conduct a variety of other internal and external attacks. A multilevel level security framework based on Onion encryption was proposed in this paper. This framework generates session keys to maintain data confidentiality, authentication and mitigates interception, fabrication attacks, Onion encryption was used to ease any effort to transform or influence paths for gaining access, and a Blockchain-based decentralized framework was used to preserve data integrity.
