Detailed ways

Hardware composition:

Embedded in the vehicle body, an embedded development board that controls the operation of the vehicle system

●The user holds the USB Key

Software composition:

●Vehicle embedded development board bootloader

●Vehicle embedded development board operating system kernel

●Vehicle embedded development board USB Key lock module program

●Certificate encryption authentication module

Only when a legal driver holds a USB Key that matches the vehicle system and holds the correct password, can he start the USB Key lock module embedded in the vehicle system and control the start of the vehicle body. Its opening process is shown in Figure 2.

After the system is loaded and running, and the car starts normally, the USB Key lock module will regularly detect the USB Key. After the user pulls out the USB Key and stops using the car body, the logout application program is completed to realize the operations such as turning off the car and rebooting the program. As shown in Figure 3.

Attached Figure 1 shows the participating entities of the core equipment that realizes the safe startup of the vehicle electronic system, including the driver, USB Key, and car body. As the system opener, the driver inserts the USB Key into the USB interface of the vehicle USB Key lock module when the car needs to be opened, and enters the user password when prompted by the system to start the car body.

Accompanying drawing 2 shows the process of powering on the vehicle-mounted system and loading the operating system kernel, which needs to be modified to customize the boot program of the vehicle-mounted system. When the system is loaded, the on-board system will first perform hardware initialization and memory mapping operations after power-on, and then the boot program will detect whether there is a USB Key inserted into the USB interface of the USB Key lock module. After the USB Key is detected, the USB Key will be legal. Authentication: first read the authentication certificate in the USB Key and compare it with the authentication certificate initialized in the USB Key lock module of the car body. After confirming that the certificate in the USB Key is correct, the system prompts the user to enter the password, and then the system reads the password and the password entered by the user. The password is set in the USB Key. After the password is successfully matched, the system boots and loads the kernel to realize the legal start of the vehicle system.

Attached Figure 3 shows the flow chart of the operation of the USB Key lock module after the system is successfully loaded; after the operating system is loaded, the USB Key lock module will regularly detect the USB Key; when the user stops using the car body and pulls out the USB Key , the system will log off the application program, realize the operations such as turning off the car, and at the same time, the system will reboot and load, and the bootloader will be blocked in the USB Key detection process.

This set of on-board software core equipment that authenticates the legality of the driver's identity can realize the safe start of the on-board system and prevent the car from being stolen. The system workflow is as follows:

a) The vehicle-mounted USB Key lock module runs after being powered on. Since there is no USB Key inserted into the USB interface, the system is blocked and waits for the driver to insert the USB Key;

b) To start the car, the driver inserts the USB Key into the corresponding USB port;

c) The USB Key lock module detects that a USB Key is inserted, reads the initialization certificate in the USB Key and matches the certificate of the USB Key lock module, and performs USB Key authentication;

d) The certificate is successfully matched, and the driver is required to enter the password;

e) The USB Key lock module reads the user input password and matches it with the password stored in the USB Key;

f) The password matches successfully, the bootloader loads the operating system kernel, and after the kernel is loaded, the application program runs normally and the car starts normally;

g) After the car is started, the USB Key lock module regularly detects the USB Key of the USB interface;

h) The driver stops using the car and pulls out the USB Key;

i) The USB Key lock module detects that the USB Key is pulled out, closes the application program to turn off the car, restarts the system, and the USB Key lock module is blocked in the USB Key detection process of the USB interface.
