Blockchain Chain Based Cloud Security Using Provable Partitioned Folding Encryption for Integrity Proofing in Cloud Environment

In current existences there has been an increase in concentration in the potential of blockchain (BC) technology to transform multiple industries, including cloud security. This study delves into the combination of BC technology and cloud security to improve data protection, authentication, and access control. The unchangeable and decentralized nature of BC suggestions a strong foundation for safeguarding cloud-based systems, reducing the vulnerabilities linked to centralized storage and single points of failure. This research investigates the fundamental principles and mechanisms of blockchain-based cloud security, such as encryption, access control, smart contracts, and disseminated mechanism. The employment of BC technology to safeguard data and transactions in cloud-based environments is referred to as blockchain security in cloud computing (CC). To defend the veracity and security of data stored in the cloud, encryption and decentralised consensus processes are used.The cloud provides decentralized service and communication all over the world through internet services. By increasing open service accessibility and sharing, the personalized information and sensitive data get unauthorized access leads security breaches, data leakage due to improves security concerns. So the security in the sense, the privacy preservation based security is an important concern to protect the sensitive data from unauthorized access. Most existing security failed in cryptographic approaches doe to key leakages and authenticity failures. To resolve this problem we provide a consensus proof of work based block chain principle (CPoW-BCP) based on provable partitioned encryption is implemented to secure the cloud environment in this research demystifying cryptographic hash function (DCHF) is applied to create portioned data block to make encryption using provable partitioned folding encryption (PPFE). With the support of post quantum chain links (PQCL) the block are stamped with randomized key policy and the hash key is updated to master node. Then master integrity proofing authentication (MIPA) verifies the user accessibility to securely handover the data. Finally the integrity proofing verification is carried out by lattice key role verification policy (LKRVP) to ensure the security to handover the data at peer end. Such the system prove the higher security to make verification and authentication to enrich the integrity on security in cloud environment. By comparing the existing system, the proposed proves higher security standard in cloud Computing and privacy standard levels. The findings suggest that block chain-based cloud security offers a promising solution for addressing the evolving threats and vulnerabilities in cloud environments, tiling the path for a further secure and resilient infrastructure.
