Research Of Information Publish System Based On Digital Certificate

The scale of road construction continues to increase,and the number of vehicles ranks first in the world in terms of total volume and increment with our country’s social and economic development.Therefore,the safety and efficiency of the travel system has become increasingly important.Expanding the scale of roads,using intelligent traffic guidance,and vigorously developing public transportation construction can effectively alleviate the pressure on road traffic and make travel more efficient.At the same time,the safety of travel cannot be ignored.In addition to traffic accidents caused by faults or accidents during driving,information security is becoming more and more important.It is foreseeable that the importance of travel information system safety will increase simultaneously with the development of unmanned vehicles.Travel information security needs to consider the information security between the vehicle and the workshop and the information security between the vehicle and the road infrastructure.This article mainly discusses the information security between the vehicle and the infrastructure.On the road,the traffic guidance information board plays a considerable role in planning road selection and future driverless driving.The traffic guidance information board needs to ensure its own stability and reliability,whether it is the driver who obtains and responds to the road status through the traffic guidance information board with the naked eye,or the unmanned car recognizes and reacts to the information on the traffic guidance information board.If the content released by the information board has been attacked,the road traffic conditions will become very poor.If illegal content is published,or even wrong traffic guidance information is published,it may cause traffic jams and causing great harm.Variable message signs are important facilities for distributing traffic information on highways.Variable message signs are important information system and important traffic control system used to support the provision of network information publishing services to the outside world.Variable message signs are a kind of transportation critical information infrastructure.The security risks in its application scenarios include source risk,link risk,data risk.It means that unaudited information is issued by others fake login system,or terminal transmission link,access business network fake communication server to publish information,or the published information data has been tampered with.This article considers this issue and conducts research on related safety systems.We are ready to use digital certificates for identity verification to ensure the reliability and authenticity of information released.We use the security authentication part to analyze and verify the information released by the host computer to prevent attacks and improve the reliability of the information released by the variable information board on the road.
