Server Security in Cloud Computing Using Blockchain

Abstract

Cloud Computing is one of the most convenient, scalable, low-cost, accessible, and highly available technologies for delivering a variety of services in the era of digitalization. However, security concerns such as data breaches, privacy issues, and integrity risks remain significant challenges in cloud environments. This paper explores the integration of blockchain technology into Cloud Computing as a potential solution to these security concerns. Blockchain is a decentralized and cryptographically secure system of linked records, known as blocks, which provides an immutable ledger that enhances data integrity and transparency. The paper will discuss the disruptive potential of blockchain in addressing the vulnerabilities of cloud services and how blockchain-based electronic wallets can ensure protection of user data in cloud environments. In addition, the paper will provide a detailed overview of applications and recent technological advancements in combining blockchain with cloud computing. This approach promises to revolutionize cloud security by leveraging blockchain, providing enhanced protection and trust for cloud users.

Introduction

Cloud computing has become essential due to its scalable, on-demand resources that reduce costs and increase operational flexibility. However, security challenges like data breaches and privacy concerns persist. Blockchain technology, with its decentralized, cryptographically secure, and immutable ledger system, offers a promising solution to enhance cloud security by ensuring data integrity, transparency, and reducing centralized control risks.

The paper explores integrating blockchain with cloud computing to improve data security, including the use of blockchain-based electronic wallets for secure transactions. It reviews literature demonstrating blockchain’s benefits in decentralizing cloud manufacturing, overcoming cloud security vulnerabilities, and enhancing supply chain transparency.

A proposed system employs blockchain to provide controlled access via personalized hyperlinks and smart contracts, ensuring secure file sharing with encrypted data and immutable audit trails. The system’s architecture includes user authentication, admin control, secure file management, and layered security measures such as RSA encryption.

Advantages include enhanced data security, controlled access, resistance to data breaches, and transparent audit logs. Future enhancements involve adding biometric security, AI-driven threat detection, mobile apps, multi-cloud integration, real-time collaboration, and improved system performance.

Conclusion

It is due to such fast-paced digitalization in different sectors that Cloud Computing has emerged as a very vital technology. Scalable resources, ease of access, and changes in the management, storage, and processing of data in business and individuals\' ways have transformed all of these. Since cloud computing works on- demand without the physical need for infrastructure, the benefits have been significant in cost savings, operational flexibility, and reach into global markets. Despite these advantages, several security issues have emerged as pressing concerns for users and service providers. Key issues range from compromising data privacy to security breaches with regards to sensitive information integrity.Taking into consideration such issues, block chain has emerged as a developing solution in response to these issues. It presents a decentralized, cryptographically secure form of data storage, with the records, or \"blocks,\" being linked and therefore immutable, ensuring integrity and transparency. Integrating blockchain with cloud computing can significantly enhance security in cloud services. Its distributed ledger system gives greater transparency while reducing the risks associated with centralized control and even in cases where data may be tampered with during a breach.
