Onion Encrypted Multilevel Security Framework for Public Cloud

Abstract

Cloud computing has evolved as a renowned 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 vulnerability issues, hackers can easily gain unauthorized access to data, launch fabrication attacks, and conduct a variety of other internal and external attacks. In this paper, a multilevel level security framework based on Onion encryption and Needham-Schroeder Symmetric Key Protocol was proposed. This framework generates session keys to maintain data confidentiality, authentication and mitigates interception, fabrication attacks, Onion encryption was used to mitigate any attempt to modify or manipulate paths for gaining access, and a Blockchain-based decentralized framework to maintain data integrity.
