Vehicular electronic secure communication system and communication method

Abstract

The invention provides a vehicular electronic secure communication system. The vehicular electronic secure communication system comprises a secure chip, a vehicular electronic system and an automobile service platform; the vehicular electronic system and the automobile service platform perform bidirectional identity authentication; the vehicular electronic system comprises an ECU control system; the ECU control system and the automobile service platform perform bidirectional signature authentication through the secure chip; and, after bidirectional signature is successfully verified, the automobile service platform and the ECU control system are in encrypted communication. The invention further provides a communication method of the vehicular electronic secure communication system. The communication method comprises the following steps that: (1), the vehicular electronic system and the automobile service platform perform bidirectional identity authentication; (2), after verification is successful, the ECU control system of the vehicular electronic system and the automobile service platform perform bidirectional signature authentication through the secure chip; and (3), after verification is successful, the automobile service platform and the ECU control system are in encrypted communication through a session key output by the secure chip.

Description

technical field [0001] The invention relates to the field of vehicle-mounted information security transmission, in particular to a vehicle-mounted electronic security communication system and a communication method, which can realize the confidentiality of data transmission with a vehicle service platform and improve the security of an electronic control unit (ECU) of a control system. Background technique [0002] With the continuous development of in-vehicle electronic systems, the functions it provides are becoming more and more complex. While providing convenience to car owners, there are also many loopholes. Hackers can remotely invade the in-vehicle system through the network, and send commands by controlling the in-vehicle system. Personal information and vehicle status, mostly send commands through the on-board electronic system to control the wiper, power system and brake system, etc., causing the accelerator and brake to fail while the car is driving, challenging th...

Problems solved by technology

[0003] Existing technical solutions can realize the control of the vehicle electronic system through the vehicle access gateway and adding security modules, but there is no clear algorithm and security process, and some only use simple passwords, which are more vulnerable to external attacks; with the ECU With the increasing number of control systems, the CAN bus of the vehicle controller area network is used to realize the connection of each control unit and build an overall in-vehicle network

Therefore, hackers can attack the ECU control system by attacking the vehicle access gateway, the Internet of Vehicles module, and communication interfaces such as Bluetooth and USB, so that the CAN bus network transmits wrong commands, thereby causing illegal operations of the vehicle control unit.
