Abstract-Cloud computing is essential for modern enterprises, providing scalable and cost-efficient solutions for data storage and processing. However, security challenges such as unauthorized access, data breaches, and insider threats persist. Traditional authentication methods like passwords and two-factor authentication (2FA) have inherent vulnerabilities, including phishing attacks, credential theft, and centralized failures [1][2]. Blockchain-based authentication offers a decentralized, tamper-proof security mechanism that eliminates single points of failure and enhances trust. Existing research has explored blockchain’s role in cloud security, but challenges such as scalability, computational overhead, and latency remain [3]. This paper presents an optimized blockchain-based authentication model that enhances access control while addressing these limitations. Our approach leverages decentralized identity management, smart contract-based access control, and an efficient consensus mechanism to improve security, reduce computational overhead, and ensure seamless authentication. This model enhances security, scalability, and performance in cloud environments, making it a viable alternative to traditional authentication systems.
