“…A blockchain dependent scheme for decentralized storage and authentication was projected in [29] for the BC solid at which the user's data was independent of the varied web application and thus switches the service of data storage can be independent of multiple web applications more easily without any trusted third party relying. At the same time, this scheme in turn guarantees the ownership of data with privacy of user through the blockchain miner leveraging for performing authentication using certificateless cryptography.…”

By the development and advancement of blockchain technique, Internet of Things (IoT) proliferation driven devices and the application of blockchain-enabled IoT alter the view and operating infrastructure of the smart networks. The blockchain is responsible for supporting decentralized systems and offers secured means of authentication, management, and access to IoT system thereby deploying smart contracts offered by Ethereum. The increasing demand and the blockchain expansion generate huge volume of sensitive data. The growing demand and expansion of blockchain-IoT systems is generating large volume of sensitive data. Furthermore, distributed denial-of-service (DDoS) attacks are regarded as the most promising threats for smart contracts in the blockchain-based systems. Therefore, there is a need to detect and classify the attack type and the data should be stored in server more securely with the use of blockchain and data aggregation method. For this purpose, this presented technique aims at introducing decentralized consensus blockchain and Interplanetary file system (IPFS) based data aggregation for effective classification and data storage. The attack is detected using meta-hyperparameter random forest (MHP-RF) classifier. Once the attack is detected, the transaction information is stored in server securely by means of smart contract-based blockchain system. The transaction handling stage classifies the transaction type as normal or abnormal one which then followed by execution of business logic by smart contract thereby appending the transaction of blockchain in the network cloud. The consensus blockchain technique is employed with the use of PoW-enabled scheme integrated with Elgamal-based data aggregation. Therefore, the system security is improved and the intrusion is prevented greatly. The performance analysis of the system is analyzed in terms of accuracy, precision, recall, F-score, Encryption time, decryption time, execution time, and space complexity. The attained outcomes are compared with traditional approaches to prove the effectiveness of proposed strategy. The proposed system is said to be effective in time consumption, classifier performance, and in overcoming space complexity issues.

“…The proposed system uses a 256 bit ECC key. To break 256 bit ECC, 10 28 MIPS years are required [42], and the current desktop computer can provide 2,356,230 MIPS [43]. Thus ECC 256 would take 4:24 Â 10 21 (10 28 Ä 2; 356; 230) years to break.…”

“…Extending the previous conference version [14] that has already reported our preliminary works, we make advances and new contributions in this journal version, including: 1) adjust our centers around the ''trust access authentication'' to conduct more in-depth work; 2) a better representative system model is proposed, which is closer to a real Solid application scenario; 3) a new digital signature scheme is applied in blockchain systems; 4) two signature reconstruction algorithms are considered, thereby making our solutions available to many more potential applications in Solid; and 5) based on the theory and assessment in our previous version, this work implements the system designs such as developing and deploying smart contracts, integrating signature schemes in the transaction validation of permissioned blockchains, and implementing our solutions to evaluate them with benchmarks. Our main contributions are listed as follows:…”

The Solid (Social Linked Data) project focuses on data sharing and privacy security and aims to build a decentralized ecosystem that radically changes the way web applications work today. Our goal is to introduce a ''trust access authentication system'' to achieve secure authentication and fine-grained access control, thereby promoting the implementation of Solid. Blockchain, equipped with multiple security properties and authentication functions, is a crucial technology. In this paper, we present a blockchainassisted system for secure authentication in Solid and for implementation of fine-grained access control policies. Specifically, we explore to integrate threshold RSA signatures in a permissioned blockchain system to enable a fault-tolerant distributed signature scheme, thereby enhancing the resilience and robustness of authentication system. Moreover, we utilize smart contract to control transaction flows and manage access control policies automatically. Experimental results show that our proposed trust access authentication system enhances security, scales well, and is efficient and economically feasible.
