【Abstract】There are still two problems of the existing methods of defending against poisoning attacks of the blockchain-based federated learning: 1) It is difficult to accurately identify the nodes under attack; 2) The effect of the model is greatly affected when the number of malicious nodes exceeds a half. So, an innovative se-cure mechanism is proposed for blockchain-based federated learning, which is called the training behavior verification mechanism. The mechanism describes the consis-tent training behavior rules of nodes by constructing the training behavior model, and distinguishes honest nodes from malicious nodes by comparing the differences in training behavior models on the training behavior verification algorithm. Ex-periments show that the new mechanism can effectively resist more than half of the label-flipping attacks and backdoor attacks, and has the advantages of higher stability and higher accuracy than methods such as Krum, Trimmed Mean, and Median.

【Abstract】Smart agriculture uses new generation technologies, such as the Internet of Things, big data, artificial intelligence, cloud computing, and blockchain to further refine and improve the intelligence of agricultural production. China considers smart agriculture as an important engine to promote high-quality agricultural and rural development. This study reviews the recent practices of smart agriculture with a case study in Zhejiang Province as well as the supporting framework and policies of smart agriculture. The study then summarizes the opportunities and challenges of smart agriculture and forecasts the future direction of agricultural technology and policies. Finally, the study offers suggestions for the acceleration of agricultural and rural development using high-quality smart technologies. The study's findings confirm that smart agriculture has become an important part of the national economy, although it is still in its infancy. Both the national and regional authorities of China have introduced policies favoring the development of smart agriculture. This has resulted in its high popularization, with perfect industrial chains and many large-scale enterprises involved in increasing the country's self-sufficiency in production and technology. While these policies have several positive effects on rural telecommunication and technology, smart agriculture faces certain constrains in terms of R&D capability, fiscal investment, farmer capacity, and talent training. By taking appropriate measures for these weak areas under unified planning, the agricultural and rural economic growth of China can be accelerated using high technologies.

【Abstract】In order to overcome the problems of long tracing time and poor tracing accuracy in traditional source tracing methods, this paper proposes a blockchain-based electronic commerce supply chain source tracing method. First, use IoT equipment to collect transaction data, store it in the cluster server in the form of blockchain, build electronic commerce supply chain traceability information base and determine the traceability query scheme. Secondly, the traceability state probability matrix is constructed to obtain the source tag variables. Then, the tracing function is constructed, and the tracing parameters are modified by Baum Welch algorithm. Finally, the Viterbi algorithm is used to obtain the tag matching function, and the recursive method is used to solve the source tracing results. The implementation results show that the tracing time of this method is only 50 s, and the tracing accuracy is as high as 99.8%, indicating that the source tracing effect is good.

【Abstract】Targeted poverty alleviation is an important strategy to win the battle against poverty. In order to solve the problems of capitalmisappropriation and false poverty alleviation in the process of targeted poverty alleviation, a targeted poverty alleviation system based on blockchain network was designed and implemented. The system creatively draws on the characteristics and advantages of consensus mechanism, irreducible modification, traceability, distributed ledger and decentralization in blockchain network to the practice of precision poverty alleviation, and realizes "blockchain + targeted poverty alleviation" rural service integration platform. The system is applied to the digital supervision of poverty alleviation funds from village-to-household in the promotion of targeted poverty alleviation work by poverty alleviation units at all levels, and truly realizes that the poverty alleviation data in each link is true, reliable, provable, traceable and auditable. At the same time, it provides solid underlying credible data support for the "last mile" problem faced by village-to-household in targeted poverty alleviation work.

【Abstract】Because the hardware capabilities of narrowband IoT devices are not enough to carry powerful antivirus software or security mechanisms so that some scholars have used deep learning to help with intrusion detection. Narrowband IoT devices are more vulnerable to low-rate denial-of-service attacks due to the low upper limit of the connection rate. However, the rate and number of such attacks are not obvious. Therefore, even when training with datasets provided by large organizations, the amount of data for low-rate denial-of-service attacks is very sparse, resulting in poor detection accuracy. This study proposes an interpretable method based on statistical models to simplify the model so that it responds only to specific attacks. The experimental results show that our method can effectively detect specific attacks.

【Abstract】Edge computing plays an important role in processing and storing data. By offloading tasks to the edge server, mobile users can access necessary computing resources on demand. However, security of edge computing service is still a major concern. This paper proposes an edge computing resource allocation mechanism based on dynamic trust. First, security problems due to lack of reliability in the resource allocation process are solved based on the trust mechanism. This mechanism considers the resource allocation process between the mobile user node and the edge server as a transaction, according to the trading behavior in the transaction process of server to give its corresponding trust. Second, a trust mechanism is used for dynamic credit granting. Mobile users with similar behaviors form a group, where a representative is elected to trade resources and bundle information into a block and attach it on the chain. At the same time, the delay problem is added as a constraint to the trust calculation. Finally, the simulation experiment shows that the mechanism improves security of edge computing.

【Abstract】Most of the current decentralized cross-domain identity management frameworks are based on blockchain. In these schemes, the identity providers (IDPs) in different trust domains connect through blockchain technology. However, a single IDP in the domain is still at the risk of being compromised or corrupted. What's more, users may create redundant identities for different services but can not dominate all their identities completely. Therefore, we propose a cross-domain identity management system based on the concept of the Decentralized Identifier standard. It provides full ownership and management of identity for users. In order to reduce the burden of private key management caused by redundant identities, we present a deduplication scheme to limit the number of one user's DIDs. It can also resist the Sybil attack by real-life identity credential. Besides that, we improve the authentication efficiency by dynamic accumulator and preserve the identity privacy by the anonymous credential and zero knowledge in the cross-domain authentication scheme.

【Abstract】This paper summarizes the main outcomes of several experimental studies carried out by the Joint Research Centre on blockchain solutions for energy systems. The cases selected for testing and implementation are: (i) smart metering billing and security, (ii) fostering of energy communities, (iii) certification of origin of energy production, (iv) support the implementation of flexibility services, and (v) electro-mobility scenarios. Overall, our study found that there is a clear interest among energy and digital industries to exploit the potential of blockchain in the energy sector. Results confirmed the added value blockchain can bring to the sector (transparency, immutability, non-repudiation, integrity), highlighting many of its unfolding functionalities and capabilities. At the same time, our study identified a number of barriers and limitations blockchain technology might encounter, such as scalability and sustainability issues, but also low consumers engagement and involvement. Finally, we conclude this paper by presenting our considerations and recommendations for European policymakers regarding blockchain deployment across the energy value chain.

【Abstract】Compared with traditional file-sharing system, the blockchain-based file-sharing system shows its superiority, such as electronic money incentive mechanism, decentralisation, information tamper resistance and so on. Benefiting from those properties, it has attracted tons of users to participate in blockchain-based file-sharing and eventually forms an indestructible electronic library. However, with such a huge amount of files, the problem of file authenticity verification is still not resolved. This paper attempts to address the challenge of file authenticity verification for blockchain-based file-sharing system, specifically, verifying that the file is really stored by the claimer and needed by the file-downloader before the file is downloaded. We propose an efficient file authenticity verification protocol, named File Authenticity Verification Byzantine Fault Tolerant (FAV-BFT). We first apply Verifiable Delay Function to bind the shared file, and then reconstruct it to a challenge-response interactive protocol for file-sharing, and finally embedded with Byzantine Fault Tolerant protocol. Due to the construction, with 2/3 of participants are honest, FAV-BFT can correctly prove how long a file has been stored and whether a file meets the requirement of the file downloader. Moreover, since all the file content is processed by hash function before transformation, FAV-BFT protects the shared-file from content disclosure during the verification process without trusted third parties.

【Abstract】Future wireless networks ((beyond fifth-generation (B5G) and sixth-generation (6G)) are expected to handle a large number of mobile and Internet of things (IoTs) devices by integrating space-aerial-ground-sea integrated (SAGSI) networks. Efficient resource management schemes in SAGSI networks are critical to tackle the challenges of seamless and high-quality wireless connectivity of heterogeneous devices anytime and anywhere. However, keeping the security and privacy of individual and integrated networks intact while optimizing resources is essential. This paper studies and discusses security issues in SAGSI networks from a resource optimization perspective. We present a survey of recent literature on how resource optimization and security are co-related in different domains of overall networks while considering artificial intelligence, machine learning (AUML), Blockchain, edge computing, secure non-orthogonal multiple access (NOMA), and software-defined networking (SDN) as potential technologies for secure SAGSI networks. We also provide future research directions and challenges in secure SAGSI networks.

【Abstract】The energy sector is undergoing a vast transformation. Innovations in renewable energy production, electric vehicles (EVs) and smart meters are pushing the energy sector towards decentralisation. In this context, determining the potential of distributed ledger technology (DLT) through smart contracts and interoperability between different sections of the grid is an open point. Implementation of blockchain as a DLT into the electricity distribution network with the combination of multiple components, assists decentralisation and the connection of end-users directly to the grid. In this paper, a new method is proposed to charge EVs based on fuzzy logic and distributed ledger using a proof of stake algorithm. In this way, the risk of manipulation and loss of data, which could be detrimental to the energy sector, is reduced. The decentralisation of controlling EV's charging is achieved using this technique and the data floating inside the network is immutable and protected by the consensus mechanism of blockchain.

【Abstract】Blockchain technology can be applied to smart grids to support business and management operations, and its distributed nature is advantageous when considering user-managed renewable systems. However, these new fully distributed systems raise a number of security and privacy issues. For this reason, numerous solutions integrating blockchain with privacy and security enhancing technologies, such as homomorphic encryption, secret sharing and zero-knowledge proof, have been proposed in the literature. The complexity of such systems from an algorithmic and protocol point of view is obvious, while the computational cost is less obvious and often overlooked by the authors. In this paper, we want to experimentally evaluate the computational weight of cryptographic techniques proposed to guarantee security and privacy on blockchains. We will take as reference commercial devices with computational capabilities similar to those we expect to find in smart grid devices. The results show that some techniques are not suitable for these scenarios and that architectural solutions must therefore be carefully designed.

【Abstract】The ongoing energy transition pathway from a fossil-based to an environmentally friendly zero-carbon energy sector passes through decarbonization, decentralization, and digitalization. The increasing digitalization empowers several key opportunities for consumers' involvement and engagement in modern peer-to-peer interactive energy communities. Among them, blockchain technology is a timely innovation that is very promising. This paper explores the potential of a recently proposed power-sharing model suitable for building-scale energy communities and blockchain-based management to foster democratic perceptions and social acceptance in non-trusting end-users. Energy communities also benefit distributors in terms of increased demand flexibility, which can result in new methodologies for managing networks and increasing the hosting capacity of networks. The relationship between individual end-users in a community and among them and the distributor are crucial aspects.

【Abstract】The use of private blockchains is proposed to enhance decentralized 5G-based DoD wireless network security, auditability, governance, and overall performance. This paper explores and validates methods for leveraging smart contracts and decentralized consensus mechanisms inherent to blockchain approaches to securely enhance wireless network performance. A real-time, decentralized architectural software implementation is postulated with detailed interfaces to determine how blockchain and smart contracts apply to real-world wireless networks based on a patented approach developed by the authors. Methods are presented for decentralized wireless networks to perform network arbitration, spectrum service level agreements, and business logic through low latency blockchain transactions. Simulation results characterize the performance of typical blockchain transaction latencies in decentralized wireless network paradigms to determine feasibility. Use case studies of federal and non-federal spectrum sharing are discussed that demonstrate how a private decentralized blockchain architecture and smart contracts can provide considerably improved wireless network performance.

【Abstract】The planning of Net-Zero Energy Factories might contribute to the better integration of power generated by volatile renewable energy sources into manufacturing systems. However, the investments needed for operating a Net-Zero Energy Factory might dissuade facility operators. The application of a blockchain might represent the missing element to make Net-Zero Energy Factories an attractive solution. The aim of this study is to present a cost-benefit analysis to plan a German carpentry as a Net-Zero Energy Factory. Businesses can increase the transparency of their energy usage by storing the Net-Zero Energy Factory's information, such as energy production, consumption and manufactured goods, in a blockchain. The increase in transparency can help to satisfy the regulatory compliance of green energy set by their respective governments. It is also helpful for businesses to demand higher prices while selling their products to customers, retailers and government projects.

【Abstract】Federated learning is a distributed machine learning frame-work that allows participants to keep their privacy data locally. Traditional federated learning coordinates participants collaboratively train a powerful global model. However, this process has several problems: it cannot meet the heterogeneous model's requirements, and it cannot resist poisoning attacks and single-point-of-failure. In order to resolve these issues, we proposed a heterogeneous federated learning algorithm based on blockchain and model distillation. The problem of fully heterogeneous models that are hard to aggregate in the central server can be solved by leveraging model distillation technology. Moreover, blockchain replaces the central server in federated learning to solve the single-point-of-failure problem. The validation algorithm is combined with cross-validation, which helps federated learning to resist poison attacks. The extensive experimental results demonstrate that HBMD-FL can resist poisoning attacks while losing less than 3% of model accuracy, and the communication consumption significantly outperformed the comparison algorithm.

【Abstract】In modern power systems, it is an important issue to process and analyze power big data and perform reliable decision-making analysis. In response to this problem, this paper proposes a distributed computing architecture for power data based on a consortium chain, which realizes distributed and trusted shared training computing for power data while taking into account the privacy protection of the original data. To solve the problem of sample imbalance, this paper proposes a data balancing method combining SMOTE algorithm and the k-means algorithm. This paper also proposes an LSTM neural network load forecasting method based on federated learning and proves that it has higher accuracy and applicability than traditional methods through examples.

【Abstract】The rapid increase of users in the blockchain makes it possible to exchange a large amount of data every moment. Since the information published on blockchain is recorded and cannot be tampered with, there is the problem of leaking the real identity of users under the big data clustering attack. Meanwhile, the existing key generation center (KGC) needs a secure channel to transmit partial private keys, which makes partial private keys depending on the channel of interaction and creates a private key security problem. In this paper, we propose a one-time anonymous certificateless signcryption (OTACLSC) scheme based on blockchain. We securely use the public channel to improve the security of the private key. By constructing a one-time pseudonym public key in the blockchain to achieve anti-identity leakage, the communication initiator constructs the pseudonym public key of both communication parties to avoid the reuse of the pseudonym public key. Then we prove the security of the scheme under the random oracle model and compare it with other schemes. Our scheme has less computation cost and shorter ciphertext length while maintaining more reliable security.

【Abstract】To enhance the dependability of lightweight blockchain, this paper presents a privacy protection mechanism in open networks with a secure ledger for each cell of society. We propose a swarm intelligence scheme called hierarchical RAFT (HRAFT), which accumulates valuable workloads about the credibility of all the nodes to sort for selecting candidates. Thus, the scheme achieves high-performance decentralization by progressive evolution consensus.

【Abstract】On the Internet of Battlefield Things (IoBT), unmanned aerial vehicles (UAVs) provide significant operational advantages. However, the exploitation of the UAV by an untrustworthy entity might lead to security violations or possibly the destruction of crucial IoBT network functionality. The IoBT system has substantial issues related to data tampering and fabrication through illegal access. This paper proposes the use of an intelligent architecture called IoBT-Net, which is built on a convolution neural network (CNN) and connected with blockchain technology, to identify and trace illicit UAV in the IoBT system. Data storage on the blockchain ledger is protected from unauthorized access, data tampering, and invasions. Conveniently, this paper presents a low complexity and robustly performed CNN called LRCANet to estimate AOA for object localization. The proposed LRCANet is efficiently designed with two core modules, called GFPU and stacks, which are cleverly organized with regular and point convolution layers, a max pool layer, and a ReLU layer associated with residual connectivity. Furthermore, the effectiveness of LRCANET is evaluated by various network and array configurations, RMSE, and compared with the accuracy and complexity of the existing state-of-theart. Additionally, the implementation of tailored drone-based consensus is evaluated in terms of three major classes and compared with the other existing consensus.
