Blockchain-Enabled Security Solutions in Cloud Computing

Abstract

Cloud computing has revolutionized the way organizations store, process, and manage data by offering scalability, flexibility, and cost-efficiency. However, as adoption has accelerated, concerns over data privacy, integrity, and security in multi-tenant environments have grown. Blockchain technology, with its decentralized and immutable ledger, offers promising solutions to address these security gaps. By integrating blockchain into cloud architectures, issues such as unauthorized access, data tampering, insider threats, and inefficient identity management can be mitigated through distributed consensus and cryptographic mechanisms. This paper explores blockchain-enabled security solutions for cloud computing, focusing on their role in enhancing data integrity, secure access control, and trustless collaboration. Furthermore, it discusses practical applications, challenges, and future directions in merging blockchain with cloud infrastructures.
