An implementation of Secure Cloud Computing mechanism for transactions using Blockchain Technology

Abstract

Blockchain is a system recording data that makes it difficult or impossible to alter, hack, or defraud the system. A blockchain is a digital ledger of transactions replicated and distributed over computer servers. Blockchain technology is a significant new financial innovation radically reshaping corporate transactions. It is a decentralized network that supports and employs multiple encryption algorithms. These safe, robust, and adaptable transactions are incorporated into another significant computer paradigm, cloud computing. This paper implements a blockchain-based secure method to make the cloud secure. Initially, the transactions are recorded in the blockchain using the SHA-256 cryptographic algorithm. After that, transactions are serialized, and block features are cached. Thirdly, the blockchain created new blocks after fulfilling desired requirements and performing transactions. Furthermore, the transaction is monitored by using the Merkle tree method in each step of the transaction to make it more secure and trustworthy. However, the research also highlighted the gaps and the impact of the gaps in the current work.

“…The aim of managing information security in cloud computing is to safeguard the infrastructure, data, and applications. 47 Cloud computing security is enforced through a variety of measures, including controls, policies, technologies, and approaches that adhere to security management regulations. The result is increased data privacy, integrity, and availability.…”

“…In cloud computing, these security measures are utilized for safeguarding data, promoting regulatory compliance, upholding customer privacy, and establishing authentication procedures for users and devices. 47 Furthermore, the implementation of cloud protection measures must be shared among both service providers and data owners. The incorporation of a fundamental secure layer in cloud computing is derived from the practices of most cloud service providers.…”

“…Data consistency and reliability maintenance are facilitated by data integrity, which also contributes to the preservation of data authenticity. 47,58 Maintaining data integrity is an essential concept that ensures any modifications to the data are executed with the user's awareness and permission. In the event of an intrusion or unauthorized access, the security of protected information may be impaired, potentially resulting in a breach of confidentiality.…”

“…An example of a security measure is cooperative provable data possession, which combines hash indexing hierarchy with homomorphic verifiable responses. 47,58…”

“…The notion of trust is multifaceted and contingent upon the conduct or demeanor of another individual. 47,58 The flexibility provided by cloud service providers is a key factor that attracts customers to their services; however, this may also expose their sensitive data to potential security risks. Consumers' need for more awareness regarding the technologies employed and the data control process can be attributed to their dependence on contracts and the trust mechanism.…”
