【Abstract】The 5G-enabled Industrial Internet of Things tilts the data processing model from the cloud to the edge. Users are more inclined to get feedback and data analysis of outsourcing computing results timely from the edge. However, the existing solutions undermine the fairness of multitask outsourcing in edge environment and cannot guarantee the correctness of results. To tackle these challenges, in this article, we propose a fair, verifiable, and privacy-preserving edge outsourcing computing scheme based on blockchain (FVP-EOC). Initially, we propose a task bidding method in the same round of task outsourcing, which improves the utilization of resources and the fairness of the FVP-EOC by dividing tasks into blocks. Furthermore, we design a result verification algorithm and a consensus algorithm to ensure the correctness of the results without a trusted third party. Finally, theoretical analysis and ample simulations indicate that the FVP-EOC is secure and verifiable and ensure the benefits of all the participants in edge outsourcing computing.

【Abstract】Thanks to the booming development of artificial intelligence, 5G technology, and intelligent manufacturing technology, numerous intelligent edge devices contained in the industrial Internet of Things (IIoT) are endowed with the ability to mine knowledge from perceived massive data. Knowledge-driven IIoT plays an unprecedented role in application fields such as cyber-physical systems and Industry 4.0. However, knowledge is generally scattered across the distributed edge devices of IIoT. Therefore, in order to further achieve the edge intelligence in IIoT, it is very important to explore an efficient edge knowledge sharing method. In this article, we establish a decentralized knowledge sharing platform in IIoT. First, for public knowledge, a dynamics model that can quantitatively describe its sharing process is established by using the system dynamics theory. Furthermore, a control method for maximizing public knowledge sharing under constraints based on the optimal control theory is presented. Second, for private knowledge, a trusted transaction control method based on blockchain technology is proposed. By developing both smart contract and lightweight consensus mechanism, the efficient peer-to-peer sharing of private knowledge is realized, and the integrity of knowledge and the privacy of participants are protected. The results of extensive experiments show that the proposed method can eliminate the obstacles of knowledge sharing among edge devices in IIoT, and further promote the development of edge intelligence empowered 5G-enabled IIoT applications.

【Abstract】Industrial Internet of Things (IIoT) and fifth generation (5G) network have fueled the development of Industry 4.0 by providing an unparalleled connectivity and intelligence to ensure timely (or real time) and optimal decision-making. Under this umbrella, the edge intelligence is ready to propel another ripple in the industrial growth by ensuring the next generation of connectivity and performance. With the recent proliferation of blockchain, edge intelligence enters a new era, where each edge trains the local learning model, then interconnecting the whole learning models in a distributed blockchain manner, known as blockchain-assisted federated learning. However, it is quiet challenging task to provide secure edge intelligence in 5G-enabled IIoT environment alongside ensuring latency and throughput. In this article, we propose a proof-of-learning consensus protocol that considers the reputation opinion for edge blockchain to ensure secure and trustworthy edge intelligence in IIoT. This protocol fetches each edge's reputation opinion by executing a smart contract, and partly adopts the winner's learning model according to its reputation opinion. By quantitative performance analysis and simulation experiments, the proposed scheme demonstrates the superior performance in contrast to the traditional counterparts.

【Abstract】Vehicular ad hoc network (VANET) is an emerging technology that can significantly improve the efficiency of transportation systems and mitigate traffic accidents by exchanging traffic-related messages or announcements. Nevertheless, there has not been a consensus on how to generate, distribute, and validate trustworthy announcements in such an untrusted wireless environment. Security and privacy, inspiration mechanism, and resource integration are significant challenges for announcement generation and dissemination. In this paper, a secure and trustworthy announcement dissemination scheme is realized for location-based service (LBS) application in VANET. A blockchain-assisted vehicular cloud (VC) architecture is proposed to harvest underutilized heterogeneous resources of vehicles participating in VANET. Moreover, the technologies of blockchain and smart contract are adopted to classify vehicles into different levels automatically by bidding for bonuses. What's more, vehicles can generate trustworthy announcements with the help of neighbor vehicles by adopting the technology of threshold signature. Meanwhile, the reputation of announcements is evaluated for trust management. Formal security analysis shows that the proposed scheme satisfies fundamental security and privacy requirements in VANET. Experimental results show that the proposed scheme is robust and efficient.

【Abstract】Industrial applications often require federated cloud services from multiple providers to improve reliability and flexibility. Traditional selection methods through auctions usually involve a centralized auctioneer to coordinate the auction procedure. Blockchain and smart contracts provide a decentralized mechanism to automate the cloud auction process; however, existing solutions fail in the selection of the most suitable providers and the violation detection of the signed auction agreements, which are also known as service-level agreements (SLAB). To tackle these problems, we propose an integrated auction model using Bayesian game theory and blockchain techniques. The proposed model is enhanced with two Bayesian Nash Equilibriums (BNEs); the first BNE enables the selection of cost-effective providers to construct the federated cloud services, while the second BNE ensures consistent and trustworthy monitoring of federated SLAB. Moreover, a timed message submission (TMS) algorithm is proposed to protect the auction privacy during the message submission phase. This paper validates the equilibrium results of two BNEs and implements the proposed model on the Ethereum blockchain. The analytical and experimental results demonstrate the feasibility, trustworthiness, and cost-effectiveness of our model. (C) 2022 The Author(s). Published by Elsevier B.V.

【Abstract】We construct an economic framework for understanding the incentives of the participants of a permissioned blockchain for supply chains and other related industries. Our study aims to determine whether adoption of blockchain is socially beneficial and whether such adoption arises in equilibrium. We find that blockchain reduces information asymmetry for consumers, thereby enhancing consumer welfare. Consumer welfare gains can be suffi-ciently large that blockchain adoption is socially beneficial; nonetheless, we find that block chain adoption does not arise in equilibrium. This situation arises because blockchain adoption costs are borne by manufacturers, and manufacturers cannot extract consumer gains through prices due to the competitive nature of the manufacturing sector. We offer a system of transfers to generate blockchain adoption in equilibrium when it is socially beneficial.

区块链技术-协同技术-物联网

【Abstract】With the development of 5G and the Internet of things (IoT), the multi-domain access of massive devices brings serious data security and privacy issues. At the same time, most access systems lack the ability to identify network attacks and cannot adopt dynamic and timely defenses against various security threats. To this end, we propose a blockchain-based access control and behavior regulation system for IoT. Relying on the attribute-based access control model, this system deploys smart contracts on the blockchain to achieve distributed and fine-grained access control and ensures that the identity and authority of access users can be trusted. At the same time, an inter-domain communication mechanism is designed based on the locator/identifier separation protocol and ensures the traffic of access users are authorized. A feedback module that combines traffic detection and credit evaluation is proposed, ensuring real-time detection and fast, proactive responses against malicious behavior. Ultimately, all modules are linked together through workflows to form an integrated security model. Experiments and analysis show that the system can effectively provide comprehensive security protection in IoT scenarios.

【Abstract】Many security standards and cryptographic solutions exist for different applications such as agriculture, aircraft, banking systems and etc. but a more effective and efficient solution can be given by combining existing technologies with blockchain. This work addresses the problems of previous works such as scalability, immutability, robustness, network latency, auditability, and traceability. Satoshi Nakamoto introduced Blockchain (BC) to tackle the Address Resolution Protocol (ARP) spoofing attacks, Distributed Denial of Service (DDoS), phishing problems and various security issues. Blockchain is a technology that stores the data using a chain of blocks in an encrypted form with hashing algorithms. It uses the decentralized architecture to store the information that helps users and customers to have transparency on records. The data is stored in a distributed ledger that is tamperproof and immutable. To amalgamate the research done so far, this paper presents a systematic review of ten different applications and tools used in blockchain. The applications include academics and education, agriculture, aircraft, banking, car sharing, e-voting, healthcare, Internet of Things (IoT), Intellectual Property Rights (IPR), and Supplychain (SC). Moreover, this paper presented a taxonomy for these applications and analyzed the implementation of tools used in different domains. Different open issues and challenges and key takeaways of blockchain technology were also highlighted. Hence, this paper helps give a new insight into working with blockchain and deciding on appropriate tools and approaches for a particular application.

区块链治理-技术治理-区块链安全

【Abstract】There is a significant drawback associated with blockchain networks in terms of their processing speed, which is one of the biggest. Due to the fact that sharding has the capability of solving this problem, the scalability of the network can be increased. One of the significant challenges in this study was determining how sharding would affect the probability of forks arising as a consequence of sharding. Towards this end, we have performed a number of experiments on the network EIP-1559 using 120 nodes in order to achieve this objective. During our analysis, we were able to determine that the number of orphan blocks on average decreases by 60% as a result of adding a shard to the system. The new on- chain governance model has also been implemented that utilizes Particle Swarm Optimization (PSO) in order to ensure that forks between different shards are reduced, as well as the probability of them occurring. The results obtained from our study give us the confidence that the proposed on- chain governance model reduces the risks associated with forking and maintains a positive user experience as a result of the results obtained.

区块链技术-核心技术-共识机制

【Abstract】Common knowledge, that is, a common understanding of environmental conditions, task objectives, coordination rules, etc., can greatly improve the collaborative efficiency of swarm robots. In many complex task scenarios, it is impossible to assume there is a central facility (e.g., a powerful robot or a back-end server that can communicate effectively with everyone) responsible for maintaining the collective's common knowledge. Instead, we must maintain it in a decentralized way. Blockchain has been proved to be an effective means of meeting this demand. It can even tolerate malicious or malfunctioning individuals to a certain extent, which is an important capability for swarm robots to operate in an open or hostile environment. However, current widely-accepted Blockchain techniques, such as Ethereum, use the proof-of-work mechanism as the basis of reaching consensus, which has to consume huge computing resources and is not suitable for swarm robots. In this paper, we present a fast and robust solution for maintaining common knowledge in swarm robots based on Hashgraph, a lightweight consensus technology being originally proposed for fully-connected, well-conditioned networks. We successfully improve its kernel mechanisms to adapt it to swarm robots with limited communication capabilities. And we novelly introduce the concept of Ranger Robot, a special kind of robot that can significantly accelerate the formation of consensus in sparsely-distributed or physically-partitioned robot swarms. Furthermore, we design a knowledge validation algorithm to enable the robot swarm to recognize attacks from a special kind of malicious robot called Byzantine robots. The results of a set of experiments based on both simulated and real robots show that our solution can greatly reduce computing overhead and accelerate the formation of consensus in comparison with solutions based on the original Hashgraph.

区块链应用-实体经济-医疗领域

【Abstract】In the field of medical image content protection and security sharing, the introduction of blockchain technology has a problem in that the secret key may be lost and cannot be recovered. Therefore, this paper proposes an authenticable medical image-sharing scheme based on an embedded small shadow QR code and a blockchain framework. First, a small shadow image is obtained by employing a secret image-sharing method based on the Chinese remainder theorem. Then, the shadow image is embedded into a QR code with error correction. This not only ensures the security and integrity of the shadow image transmission in the public channel but also avoids the problem where the secret key is lost and cannot be recovered. Compared with some existing excellent schemes, our scheme adopts a hash bit stream for authentication purposes and employs smart contracts to authenticate and restore secret images, thus reducing the local load. In addition, experiments validate that the recovered secret medical image is lossless and that the cover QR code is more robust and secure. This method is suitable for medical image content protection and security sharing.
