Blockchain Technology in Cloud Security

Abstract

As cloud computing becomes ubiquitous, the need for robust security measures intensifies. Traditional centralized access control systems in cloud environments pose vulnerabilities such as single points of failure, transparency deficits, and privacy concerns. This chapter explores the integration of blockchain technology as a transformative approach to enhancing cloud security. Blockchain, renowned for its decentralized ledger, immutability, and cryptographic security, offers innovative solutions to these challenges. The chapter discusses the motivation behind adopting decentralized access control, the fundamentals of blockchain, and its role in identity management. Real-world use cases demonstrate the practical application of blockchain in cloud security. Challenges, including scalability and regulatory compliance, are addressed. This chapter provides a comprehensive introduction to decentralized access control in cloud security, emphasizing its potential to revolutionize the field and contribute to the development of secure and resilient cloud systems.
