“…Thus, without any interruption, the data stored in the cloud is replicated on Blockchain nodes, optimizing data efficiency and data validity. In a construction project, the discipline privacy is also guaranteed by Blockchain, and the record can be securely encrypted from the system to prevent third-party access to the data [33]. In addition, the cloud and the Blockchain can be used with BIM to help the building sector in becoming sustainable and more functional while making a valuable contribution to the digital transformation of the construction industry.…”

“…The integration of BIM with Blockchain represented an opportunity to assist the construction stakeholder to solve the issue of transparency and increase the performance of the overall building project by offering benefits such as value transfer for digital assets, digital identification, certificate facilities, and security [43] In previous studies, Nader & Jameela [44] propose a middleware Blockchain approach to support smart manufacturing applications with Blockchain services to enable more secure, reliable, traceable and autonomous smart manufacturing applications. The solution is developed as a cloud-integrated architecture by combining it with Blockchain technology [33]. Hasan et al [4] propose a Blockchain-based digital twin system that ensures reliable and transparent transaction, and data provenance track-andtrace, availability, and immutability.…”

“…BC is an unaltered chain of data connected in a decentralized manner to oppose the cloud's centralized approach. If an attacker anyhow gets access to data stored on the BC, only that piece of data is leaked, the rest data will remain safe as it is stored in different blocks on different remote servers which are owned by different organizations [4]. Decentralization in a cloud can be achieved using Ethereum BC or Hyperledger BC method and Ciphertext Policy Attribute-based Encryption (CP-ABE) algorithm [5].…”

This research paper puts emphasis on using cloud computing with Blockchain (BC) to improve the security and privacy in a cloud. The security of data is not guaranteed as there is always a risk of leakage of users' data. Blockchain can be used in a multi-tenant cloud environment (MTCE) to improve the security of data, as it is a decentralized approach. Data is saved in unaltered form. Also, Blockchain is not owned by a single organization. The encryption process can be done using a Homomorphic encryption (HE) algorithm along with hashing technique, hereby allowing computations on encrypted data without the need for decryption. This research paper is composed of four objectives: Analysis of cloud security using Blockchain technology; Exceptional scenario of Blockchain architecture in an enterprise-level MTCE; Implementation of cipher-text policy attribute-based encryption (CP-ABE) algorithm; Implementation of Merkle tree using Ethereum (MTuE) in a Multi-tenant system. Out of these four objectives, the main focus is on the implementation of CP-ABE algorithm. CP-ABE parameters are proposed for different levels of tenants. The levels include inner tenant, outer tenant, Inner-Outer-Tenant, Inner-Outer-External-Tenant, Outer-Inner-Tenant, External-Outer-Inner-Tenant and the parameters such as token, private key, public key, access tree, message, attribute set, node-level, cipher-text, salting which will help in providing better security using CP-ABE algorithm in a multitenant environment (MTE) where tenants can be provided with different levels of security and achieved 92 percentage of authenticity and access-control of the data.

“…Software as a service (SaaS) is the first service that is like an application that is hosted by internet-wide users. As a single source for the apps operating in the cloud, the cloud service provider provides full programmes or initiatives that have several resources for each of the customers [6]. Cloud clients have no cloud infrastructure access.…”

Blockchain technology is a shared database of logs of all consumer transactions which are registered on all machines on a network. Both transactions in the system are carried out by consensus processes and to preserve confidentiality all the files contained cannot be changed. Blockchain technology is the fundamental software behind digital currencies like Bitcoin, which is common in the marketplace. Cloud computing is a method of using a network of external machines to store, monitor, and process information, rather than using the local computer or a local personal computer. The software is currently facing multiple problems including lack of data protection, data instability, and reliability. This paper aims to give the highest security for multiple user environments in cloud for storing and accessing the data in blocks. The users who are legitimate are only allowed for storing and accessing the data as like a secured block chain approach. As like the Blockchain which does not require a centralized system for transactions, the proposed system is also independent on centralized network interface. The decentralized system is developed in such a way to avoid counterfeiting. The system enables the fabricator to spend less or null resources to perform the validations for its direct operated stores. This ensures the product fabricator to avoid the circulation of its duplicate products. The customer as an end-user is also ensured to have only the genuine products from the fabricator. The Fabricator (F), Merchant (M) and consumer (C) forms an interconnected triangular structure without allowing any counterfeiting agents in their secured cloud chain. The proposed approach provides the stability in the security system of the cloud using the chaining mechanism within different blocks at each node. It takes roughly 4.7, 6.2, and 7.5 ms, respectively, to register each node in the proposed system for 5, 10, and 15 nodes. The overall registration time for each scenario is 11.9, 26.2, and 53.1 ms, despite the fact that each node's registration time was greatest for 10 nodes. By looking at the data, it's clear that the number of nodes is a function of time.
