A Secure and Smooth Data Delivery Platform with Block chain in Cloud Computing

Cloud computing has emerged as a transformative paradigm, providing scalable and on-demand access to a variety of computing resources. However, concerns about the security and integrity of data in the cloud persist. This study proposes a novel approach to enhance the security and efficiency of data delivery in cloud computing through the integration of blockchain technology. The proposed system leverages the decentralized and tamper-resistant nature of blockchain to establish a secure and transparent data delivery platform. Blockchain's distributed ledger ensures the integrity of data by recording transactions in a way that is resistant to modification. Smart contracts, executable code within the blockchain, are utilized to automate and enforce secure data delivery protocols. To achieve smooth data delivery, a decentralized consensus mechanism is implemented, eliminating the need for a central authority and mitigating the risk of a single point of failure. This not only enhances security but also improves the overall reliability and availability of the data delivery platform. The integration of blockchain also introduces cryptographic techniques for secure data encryption and access control. Each data transaction is cryptographically signed, providing a robust mechanism for authentication and authorization. Additionally, the use of private and public keys ensures that only authorized parties can access and modify the data. Furthermore, the system incorporates a dynamic and adaptive resource allocation model, optimizing the utilization of cloud resources based on real-time demand. This ensures that the data delivery platform remains scalable and cost-effective while adapting to changing workloads. The proposed solution is evaluated through a series of experiments, demonstrating its effectiveness in enhancing security, transparency, and efficiency in cloud-based data delivery. The results indicate a significant reduction in vulnerabilities, improved data integrity, and increased overall system performance.

I. INTRODUCTION

Data security is a critical concern in today's digital age, where vast amounts of sensitive information are generated, transmitted, and stored. Traditional centralized approaches to data security have shown vulnerabilities, as centralized systems can be susceptible to hacking, data violations, and unauthorized access. Blockchain is a technology has become a viable means of improving data security in response to these issues. Blockchain is a distributed, decentralized ledger technology that guarantees tamper resistance, consistency, and visibility. Although it is most known for being the technology behind crypto currencies like Bitcoin, its uses go far beyond virtual money. Its inherent features make it well-suited for enhancing data security in various industries. Because centralized servers are the foundation of traditional data storage, they are a single point of failure. On the other hand, block chaining does away with the necessity for a central authority by distributing data among a network of nodes. The decreased possibility of a single point of compromise brought about by this decentralization enhances protection. It is nearly impossible to remove or change data once it is added to a block chain. A chain of blocks is created by connecting each block in the chain with the prior block's cryptographic hash.
