Under the guidance of these policy documents, the development of China's car networking industry has further accelerated and the scale of the industry has continued to expand.

On September 6th, at the 2019 Fair of Intelligent Transportation and Internet of Vehicle Industry Development Summit, the implementation plan for the establishment of the national-level Jiangsu (Wuxi) Vehicle Network Pilot Area was officially released. On September 7, Miao Wei and Wu Zhenglong jointly unveiled the first car networking pilot area in the country in Wuxi, Jiangsu.

Miao Wei proposed to combine 5G commercial deployment, give play to China's foundations and advantages in network technology, pilot demonstration, industrial integration, institutional mechanisms, etc., accelerate the integration of 5G and vehicle networking innovation; focus on automotive chips, computing platforms, vehicle operating systems Such as "card neck" technology links, to achieve breakthroughs one by one, support qualified regions and enterprises to try first; promote the improvement of relevant laws and regulations, accelerate the construction of the car networking pilot zone, strengthen the management mechanism and operation mode exploration, improve the level of security protection technology, Guarantee the healthy development of the car networking industry.

Some experts believe that the development of the car networking industry is conducive to improving the level of auto networking and intelligence, achieving automatic driving, developing intelligent transportation, promoting information consumption, promoting structural reforms on the supply side, promoting the construction of a strong country and a network powerhouse. Achieving high quality development is of great significance.

Play a key role in network security

The development of the Internet of Vehicles is a profound change involving the value chain, the industrial chain and the innovation chain. During the "13th Five-Year Plan" period, China will take scientific and technological innovation as the guide, take the intelligent network as the main direction, and strive to create new business and new kinetic energy to promote the automotive industry. Transformation, efficiency, upgrading, and implementation from large to strong.

Zhao Zhiguo, director of the Network Security Administration of the Ministry of Industry and Information Technology, believes that "the Internet of Vehicles is a new thing. It has a new industrial form, a large industry span, and a wide range of applications. Its perfection and development require vehicle manufacturers, component R&D companies, Internet companies, and universities. Research institutions and other scientific research institutions work together to explore and coordinate."

Li Yunfeng, inspector of the Network Security Coordination Bureau of the Central Network Office, proposed to strengthen the strength of the entire industry, and continue to increase R&D, innovation and investment from technology, standards, management, and even industrial systems and personnel training to build a people-centered The vehicle network security system protects the security of terminal (vehicle) link data; it is necessary to realize that only by making network security an important prerequisite can we better promote the healthy development of the automobile industry.

"Without cyber security, nothing can be said." In the view of Shen Changxiang, an academician of the Chinese Academy of Engineering, security is the premise of development, and development is a guarantee of security. Cybersecurity threats and protection are eternal themes, and cyberspace is much more fragile than imagined. The traditional "blocking and killing" has been difficult to cope with attacks. It is necessary to establish a computational framework for active immunization. By constructing an active immune triple protection framework supported by a trusted security management center, the calculation results can be measured and controlled, protected and calculated. Coexisting active immune computing mode. Shen Changxiang said frankly, “The Internet of Vehicles is a typical Internet of Things. It is necessary to simplify the complex problems with the hierarchical protection security management center architecture and form a security management center according to the level protection requirements.”

With the advent of the 5G era, the Internet of Vehicles is a worry? The Internet Emergency Center researcher Wang Yongjian said that in the 5G environment, the Internet of Vehicles faces intelligent networked cars, mobile intelligent terminals, car networking service platforms, car network wireless communications, and car network data security. And privacy protection five categories of security threats. The security risks introduced by 5G generalized access in the wireless communication link are: traffic attack, identity forgery and malicious interference.

To this end, Wang Yongjian suggested that in the technical monitoring means, it is necessary to study the intelligent abnormal traffic monitoring mechanism based on deep learning and other technologies, improve the security protection capability of the vehicle network, provide monitoring and early warning functions and network control functions; research based on 5G authentication framework and communication Encryption algorithm, build a trusted "human-vehicle-road-cloud" collaborative communication, realize timely identification and alarm of unauthorized access; at the same time, study abnormally strong interference monitoring and positioning technology, based on intelligent layout monitoring system of roadside facilities, Real-time monitoring of important frequency bands to achieve coordinated positioning of abnormal interference source locations for systems such as satellite navigation.

Building a network trust support platform

How to deal with the security risks faced by the Internet of Vehicles? The experts from the conference made recommendations from multiple angles.

"Automobile network security trust system is an important means to solve the problem of car network security." Zheng Jihu, director of the Data Resource Center of China Automotive Technology and Research Center, said that in order to solve the problems faced by the automotive industry in establishing a network trust system, China Auto The center cooperates with relevant enterprises, universities and research institutes to jointly build a trust support platform for the vehicle network, and provide network security for the intelligent and networked development of the automotive industry.

It is worth noting that the "China Car Network (Intelligent Networked Cars) Network Trust Alliance" was launched on the forum. According to Zheng Jihu, the alliance aims to build a trust platform for a better car network network and open up the upstream and downstream industry chain of the car network network trust system.

Yang Bin, senior vice president of Tianrongxin Company, pointed out that “To do a good job in vehicle network security protection, it is necessary to learn from the IT network security protection technology, combined with the vehicle networking business scenario, and use a variety of protection technologies to coordinate linkage.”

“For example, through authentication and encryption technology, it can realize trusted identity authentication, communication encryption transmission in the car network, the car and the cloud, the car and the mobile phone, and prevent attack attacks such as command cracking, replay attack, forgery identity, data stealing, etc.” Yang Bin said. Through the white-list-based in-vehicle intrusion detection technology, combined with the reporting of security incidents and the delivery of cloud policies, it can detect attacks such as abnormal traffic and abnormal packet recognition.

For example, through the in-vehicle security gateway, the in-vehicle security domain is isolated to achieve access control, CAN packet depth detection, security audit, intrusion prevention, etc. among the key interconnect components in the vehicle, thereby realizing the security protection of the in-vehicle network boundary.

Regarding how to do a good job in the safety of the Internet of Vehicles, Zhao Zhiguo put forward five suggestions: First, fully understand the importance and urgency of vehicle network security; second, accelerate the breakthrough of the core technology of vehicle network security; third, promote the improvement of the vehicle network security system; It is to strengthen the protection of the talent team; the fifth is to strengthen international exchanges and cooperation.

Guo Yansong, deputy director of the Technology Center of Great Wall Motor Co., Ltd., called for the establishment of industry-recognized vehicle network security data; at the same time, the development of automotive network security solutions for China's national conditions; in addition, to accelerate the development of standards, certification and access systems, Let companies in the industry do what they can.
