AI Technical Summary

Technical Problem

In the field of smart cars, the diagnostic instrument has a security risk to access vehicle-related data, and the conventional security verification mechanism cannot effectively prevent the diagnostic instrument from maliciously accessing any data in the vehicle.

Method used

By providing a first device in the vehicle, the device receives an access request from the diagnostic device and performs security verification based on the legal binding relationship between the diagnostic device and the vehicle. After verification is passed, the device allows the diagnostic device to access data in the vehicle and avoids the diagnostic device from obtaining the key of the ECU in the vehicle through an isolation mechanism.

Benefits of technology

Improve data security and vehicle security during data access, prevent diagnostic equipment from maliciously accessing data in the vehicle, and avoid the risk of ECU key leakage.

Abstract

The invention discloses a security access method, device and system and a vehicle, relates to the technical field of security control, and can improve data security and vehicle security in a data access process. In the scheme, when the diagnostic equipment has a demand for accessing a certain vehicle, the diagnostic equipment can send the access request to the first device on the vehicle and carries the first information used for indicating the legal binding relationship between the diagnostic equipment and the vehicle, and the first device can send the access request to the first device after the first device performs security verification based on the first information. A diagnostic device is allowed to access the vehicle. On the basis, the influence on other vehicles when one vehicle has potential safety hazards can be avoided by performing authorization management on diagnosis equipment and vehicle dimensions; besides, the isolation effect provided by the first device enables the key of the ECU in the vehicle to be invisible to the diagnosis equipment, so that the risk of key leakage of the ECU in the target vehicle is avoided, and the influence on the safety of the target vehicle and other vehicles can be avoided.
