车联网交互信息控制传输与安全共享方案
Vehicle networking interactive information control transmission and security sharing scheme
摘要
Abstract
The application of alliance chain in vehicle networking to achieve road traffic observation information manage-ment can take into account the decentralization of public chain and the efficient characteristics of private chain,and im-prove the transparency of communication between vehicles.However,existing schemes do not adequately consider the risk of malicious vehicles and malicious road side unit(RSU)nodes spreading false information,which can lead to urban traffic paralysis and accidents.In addition,the transmission of massive vehicle data and repeated incident reports in-creases the computing and communication overhead,which affects the feasibility and scalability of the system.Aiming at the above problems,a control transmission and efficient and secure sharing scheme for interactive information in the vehicle-connected scene was proposed.Firstly,an information transmission control strategy based on angular difference self-transforming area code was designed.The amount of information forwarded was limited by setting the threshold of vehicle area code distance,and Bloom Filter was adopted to filter information to reduce the transmission of redundant in-formation.Secondly,a management mechanism based on credit points was established to deal with the damage to the sys-tem caused by malicious nodes spreading false information.Finally,the DMML-Hotstuff(dynamically manage multiple leader Hotstuff)consensus algorithm was proposed,which effectively solved the performance bottleneck of single master node.The system throughput and Byzantine tolerance were improved by dynamic node adjustment.The simulation results show that the proposed scheme reduces the vehicle information transmission by 23%and 39%compared with the existing methods,and can evaluate the credit score in real time and quickly identify and isolate malicious nodes.In terms of con-sensus algorithms,the throughput is improved by 19%,52%and 188%,respectively,compared to the three mainstream Byzantine fault-tolerant algorithms.关键词
