“…2: Hash value generation in the Blockchain network [17] The Blockchain technology is employed to validate the user authentication through the hash value function generated for each transaction. The transaction history is stored in an immutable decentralized ledger [18] that ensures the secured channel establishment. The chain of blocks corresponds to the different transactions which are build using the entities like transaction id, previous hash function, user key, private key, password, functional attributes, etc.…”

Purpose: In the digital era, secured financial transaction is a challenging task for the banking sector when involving a third-party service provider. With the extended knowledge about networks and security, hacking and attacks are also being updated accordingly. The hackers always aim to attack the financial transaction server to duplicate the session or to impose on the user through their identity. This type of attack always occurs in a weak server where the transactions were not protected by a proper methodology. Design/Methodology/Approach: This model is developed using the elliptical curve encryption technique integrated with the chaotic map encryption algorithm for the Blockchain networks in the cloud environment. The security of the transaction is assured through the hash functions generated during each transaction and the different factor authentication of the user and the server. Findings/ Results: The computational time of the proposed model is reduced by 33% than the existing models and the encryption and decryption costs were also minimized by 18 % and 15% respectively proving the efficiency of the proposed model.

“…Blockchain technology verifies the user's authentication process and the hash value function generated using the transaction between the user and the banking server. The transactions performed by the user are will be stored in the hyper-ledger technology [19] which is a distributed enterprisegrade that provides a high level of security. The chain of blocks is composed of multiple transactions which are composed of transaction id, previous transaction id, user's public key, low entropy password, chain code function, functional parameters, etc as depicted in Figure 2.…”

The progression of digital technology impacts the users to migrate from traditional financial transactions to the online transaction system for performing their financial transactions. The existence of cloud computing and its major benefit of access from anywhere promotes financial transactions. The cloud infrastructure supporting performing financial transactions deals with the huge volume of data and it is quintessential to sustain a high level of security to those sensitive credentials in the cloud storage. The conventional cryptographic algorithms hold good in providing a better level of security to the sensitive data in cloud computing but still fall back to advanced attacks against the cloud data storage. Furthermore, the employment of conventional encryption algorithms in securing the cloud data consumes huge execution time, as it has to perform the authentication check for all types of user access including legitimate and non-legitimate accesses. This research article proposes a novel methodology of incorporating blockchain technology to perform online financial transactions in cloud computing with a high level of security, availability, and reduced execution time. This research work employs Blockchain technology integrated with Elliptical Curve Cryptography (ECC) and Chaotic Map Confusion and Diffusion algorithm to perform secured transactions over a cloud network. The interpretation of the proposed method contributes to better performance in the aforementioned parameters than the existing methodologies. The proposed framework is compared with the conventional method of online transactions using Multi-Factor Authentication (MFA) encompassing the Elliptical Curve Cryptography (ECC). The performance analysis proves that the proposed framework exhibits a high level of security along with reduced computational time, encryption, and decryption cost. The proposed work is interpreted with sample dataset and the computational time is reduced.

With the rapid development of the social economy, the problem of environmental pollution has been widely concerned. The existing environmental monitoring system adopts a hierarchical centralized management structure, which has some problems, such as data silos and the risk of data falsification. Thus, this paper proposes an environmental monitoring data security model based on the blockchain, which uses the blockchain distributed storage mode to realize the secure sharing of monitoring data and curb the behavior of data forgery. A practical Byzantine fault tolerant mechanism based on credit grouping supervision is adopted to reduce the computation and communication overhead caused by data consensus. Through the cloud chain fusion technology, the encrypted monitoring data is stored on the cloud storage server, and the monitoring data credentials are stored on the blockchain to reduce the storage pressure. And AES(Advanced Encryption Standard) combined with the RSA (Rivest-Shamir-Adleman) encryption algorithm to ensure the security of data transmission and storage. Security analysis and experiments demonstrate that our proposed scheme achieves authenticity, integrity, and security for monitored data. In addition, it effectively reduces the computation, communication, and storage overhead of the block nodes.INDEX TERMS Environmental monitoring, blockchain, data security, practical Byzantine fault tolerance mechanism, cloud chain fusion.
