“…Similar to the stock dividend system, people who possess comparatively greater shares might get higher dividends. Therefore, it is more energy-efficient than PoW and provides higher sustainability [ 48 ]. The nodes with stakes are meant to be trustworthy and refrain from manipulating transactions, but if they do, their stake might be taken away.…”

“…PoS outperforms PoW in terms of speed as well. For instance, Ethereum can handle up to 100,000 transactions per second using PoS, but it can only handle 30 transactions per second with PoW [ 48 ]. In the case of PoS, however, there is a possibility that a node will not have enough assets, in which case, if it were to be chosen as a miner, it would be viewed as malicious since it would have no assets to be debited [ 47 ].…”

“…Gao et al [ 48 ] provided a new framework called SGX in the IoT-cloud medical health (IoMT) using BC with FC integration to maintain a trusted environment and data confidentiality. To maintain the highest level of data protection, only a portion of the relevant diagnostic data can be given to the medical facilities in need.…”

The fog computing concept was proposed to help cloud computing for the data processing of Internet of Things (IoT) applications. However, fog computing faces several challenges such as security, privacy, and storage. One way to address these challenges is to integrate blockchain with fog computing. There are several applications of blockchain-fog computing integration that have been proposed, recently, due to their lucrative benefits such as enhancing security and privacy. There is a need to systematically review and synthesize the literature on this topic of blockchain-fog computing integration. The purposes of integrating blockchain and fog computing were determined using a systematic literature review approach and tailored search criteria established from the research questions. In this research, 181 relevant papers were found and reviewed. The results showed that the authors proposed the combination of blockchain and fog computing for several purposes such as security, privacy, access control, and trust management. A lack of standards and laws may make it difficult for blockchain and fog computing to be integrated in the future, particularly in light of newly developed technologies like quantum computing and artificial intelligence. The findings of this paper serve as a resource for researchers and practitioners of blockchain-fog computing integration for future research and designs.

“…Y. Gao et al [32] proposed a framework employed with Hyperledger Fabric and Intel SGX (Software Guard Extension) in order to utilize blockchain technology for authentication of IoMT devices and cloud service providers and for providing an access policy management mechanism for health data. In this work, the software guard extension technology is integrated with edge computing, ensuring the integrity and confidentiality of IoMT data.…”

The advent of wireless technologies and the development of more and better globally connected mobile devices, leverage real time health monitoring. Mobile health (m-health) promise to deliver health services anytime and anywhere, improving user convenience and enabling faster diagnoses without the need to travel to healthcare facilities. The use of m-health applications on mobile devices with the support of cloud computing is nowadays a technology trend that has many advantages, but also poses several challenges, especially on the data storage and privacy. Blockchain technology is an exponentially growing technology used in various research areas from finance, voting mechanisms, production chains, among others. This technology provides important characteristics such as immutability, non-repudiation, transparency, and reducing the need for intermediaries. Hence, this paper presents a novel approach for blockchain technology applied to m-health systems. This proposal allows an easy and fast integration with other health systems or applications allowing a patient-user to access his electronic health record in a more secure way. The data is traceable throughout the system, however maintaining the necessary anonymity. Hence, a prototype for a blockchain-based solution using Hyperledger Fabric was developed. This implementation enables the creation of a chronologically organized and immutable health data record. To create an anonymous storage system, the proposed system uses two separate database components that maintain data traceability through sets of IDs stored in the blockchain. Furthermore, the development of the proposed system was evaluated in terms of performance and network configurations of the Hyperledger Fabric.

“…No one, but the CPU, can access the code and data in it. SGX can now provide a trusted execution environment for many application scenarios, such as by introducing a trusted execution environment in edge computing, that is, software protection extension technology, to ensure the confidentiality of the medical IoT data analysis process [22]. ere are also applications of SGX to verifiable confidential cloud computing, which guarantees code and data confidentiality, as well as the correctness and integrity of its results [23].…”

The control flow hijacking attack poses a serious threat to the integrity of the software. The attacker exploits the loophole to hijack the control flow of the running program to achieve the purpose of the attack. Remote control flow attestation is a method for embedded devices to ensure the integrity of the software. With the continuous development of Internet of Things (IoT) technology, embedded devices have exploded. None of the existing control flow attestation schemes can adapt to the real-time attestation requests of such massive embedded devices. This paper proposes a blockchain-assisted distributed fog computing control flow attestation scheme BDFCFA to deal with this scenario. The scheme uses a simplified control flow representation model, which can effectively represent the control flow of the program and reduce the runtime overhead of the prover in the attestation process. We use SGX technology to protect the integrity and confidentiality of verifier and prover data during the attestation process. Our proposed bidirectional control flow attestation protocol based on the elliptic curve can greatly protect the communication security between verifiers and provers without incurring excessive performance overhead and communication cost. We evaluate the performance of BDFCFA through the SNU real-time benchmark and demonstrate that BDFCFA has better performance. Finally, compared to the existing remote control flow attestation scheme, the results show that BDFCFA has the highest security.
