Blockchain-based computing and wireless communication resource joint management double auction model by Yan SUN, Ao XIONG, Chengling JIANG, Wei WANG, Dongxiao YU, Shaoyong GUO

“…In wireless communication networks, the stock of spectrum, computing, storage and other resources at the edge was limited.The traditional decentralized and exclusive resource allocation resulted in weak resource reuse capability and low utilization rate.At the same time, it was difficult to ensure the fairness of resource sharing in the traditional resource scheduling process due to the lack of trust between the owners.First, a double auction model of computing and wireless communication resource joint management based on blockchain was proposed.In the model, a resource market was established, in which resource buyers and sellers allocated resources through double auctions.Secondly, blockchain was used to store the resource information of buyers and sellers to solve the mutual trust problem of all parties in the network.Finally, the experimental simulation was carried out to verify that the proposed model effectively improved the system performance and resource utilization efficiency.…”

Research on a new network covert channel model in blockchain environment by Yanfeng LI, Liping DING, Jingzheng WU, Qiang CUI, Xuehua LIU, Bei GUAN

“…Blockchain is a decentralized architecture emerging with cryptocurrencies,which is credible and robust.A network covert channel model in blockchain environment was proposed for the first time,which was anti-interference,anti-tamper modification,multi-line communication,receiver anonymity and line independence.The shortcomings of network covert channel in existing network environment could be tackled by the new type of network covert channel,such as characteristic defect.etc.Firstly,A network covert channel model in blockchain environment was presented by formal method,its anti-interference and anti-tamper modification was proved.Then,a blockchain network covert channel scenario using service operation interval time was presented.Finally,the undetectability,robustness and rate of the blockchain network covert channel evaluation vectors was proposed.A theoretical foundation was laid for the practicality of the new type of network covert channel in blockchain.…”

Leveraging edge learning and game theory for intrusion detection in Internet of things by Haoran LIANG, Jun WU, Chengcheng ZHAO, Jianhua LI

“…With the commercialization of 5G and the development of 6G, more and more Internet of things (IoT) devices are linked to the novel cyber-physical system (CPS) to support intelligent decision making.However, the highly decentralized and heterogeneous IoT devices face potential threats that may mislead the CPS.Traditional intrusion detection solutions cannot protect the privacy of IoT devices, and they have to deal with the single point of failure, which prevents these solutions from being deploying in IoT scenarios.The edge learning and game theory based intrusion detection for IoT was proposed.Firstly, an edge learning based intrusion detection framework was proposed to detect potential threats in IoT.Moreover, a multi-leader multi-follower game was employed to motivate trusted parameter servers and edge devices to participate in the edge learning process.Experiments and evaluations show the security and effectiveness of the proposed intrusion detection framework.…”

Application of blockchain technology in the demand response management of power grid by Haowen REN, Yaqi YANG

“…The theory of decentralized blockchain mechanism was studied,and a method of applying distributed block chain technology to manage demand response planning in smart grid environment was proposed.This method was based on the blockchain distributed ledger accounting tamper-proof technology,which stored the energy consumption information collected from the intelligent metering devices of the IoT,and defined the self-executing intelligent contract at each consumer level in a programmatic way to ensure the flexibility of transactions.Blockchain distributed technologies provided incentives or penalties to balance energy demand with grid energy production rules.Consensus-based validation would be used to validate demand response plans and provide appropriate financial settlement for flexible suppliers.The results show that the power demand side management based on blockchain distributed technology can be used to match energy demand and production under the condition of smart grid,with high accuracy of demand response signal,but less flexibility required for convergence.…”

Block-based fair payment scheme under delegation computation by Ta LI, Youliang TIAN, Kang XIANG, Hongfeng GAO

“…In the traditional delegation computation,due to the self-interested behavior of both participants,there were some problems such as the denial of the principal and the dishonest calculation by the computing party.In the payment phase,a third party was required to ensure the fairness of the payment,which led to extra costs and risks of disclosure of participants' privacy.Game theory was used to analyze the Nash equilibrium solution between the two parties in the payment process,and a fair payment protocol based on time commitment of bitcoin was proposed.Firstly,the bitcoin time commitment technology was used to ensure the fairness of payment.Secondly,the decentralized feature of block chain was used to replace the third-party service to protect the privacy of all parties and realize the source of responsibility.Finally,the scheme was analyzed from the perspective of security and correctness,which proved that the participants choose behavioral strategies honestly in the payment process.The scheme proposed in this paper not only solved the problem of fair payment in traditional delegation computation,but also protected the privacy of participants.…”
