Intelligent network connection automobile information safety platform based on end-pipe-cloud

Abstract

The invention discloses an intelligent networked automobile information security platform based on end-pipe-cloud, and the platform carries out the security protection for a vehicle end, a cloud platform, and an Internet, and a trusted execution environment and a security level for the domain isolation, the deep defense, and the software and hardware integration are built at the vehicle end. Nodeverification, file layer encryption protection and key management service are established at the cloud end, and SSL / TLS secure communication is used between the nodes and between the nodes and the application program. For a communication network, a PKI-based communication encryption mechanism, a real-time network abnormal flow monitoring mechanism, an end-pipe-cloud integrated intrusion detectionmechanism, a national vulnerability perception and early warning mechanism and a multi-stage collaborative emergency response and online upgrading mechanism are established. And a data life cycle management mechanism, a key security storage management mechanism and a key data security storage management mechanism are established for data of the vehicle end and the cloud end. The establishment of the information security platform is the first example in the field of intelligent connected automobiles at present, and lays a foundation for the construction of national security systems.

Description

technical field [0001] The invention relates to intelligent Internet information security technology, in particular to the information security architecture of intelligent networked vehicles. Background technique [0002] With the application of technologies such as the Internet, artificial intelligence, cloud computing, and big data, the degree of intelligence and networking of automobiles is getting higher and higher. At present, motor vehicles have already completed the transition from centralized manual control to distributed electronic automatic control. The transformation, efficient vehicle network system, and the popularity of numerous communication interfaces, especially the application of vehicle information system (Telematics), have posed new challenges to vehicle safety. Therefore, it is possible for an intruder to avoid direct physical contact and instead establish a remote wireless connection, control the vehicle bus system by attacking software security vulnera...

AI Technical Summary

Problems solved by technology

[0005] Automotive information security risks mainly involve the following aspects: first, the on-board diagnostic system interface is vulnerable to hacker attacks; second, the vehicle bus network CAN adopts a standard network and is vulnerable to hacker attacks; third, there are security risks in vehicle applications; fourth, there are security risks in network connections Fifth, the safety protection measures of the vehicle domain network communication protocol are insufficient

In China, due to the late start of this technology, the high confidentiality of this technology abroad, and the high cost of independent research and development, most of the research on this technology stays at the level of theoretical academics, and there are few practical applications of productization.

[0006] Overall, the information security protection of the existing intelligent networked vehicle information service platform in China is insufficient, and the security protection of the intelligent networked vehicle terminal system is seriously lacking.
