Embodiment Construction

[0124] In order to make those skilled in the art better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0125] In-vehicle equipment refers to the equipment on the vehicle that assists driving or provides convenience for users, including ADAS, ECUs, vehicle rear-view mirrors, vehicle refrigerators, etc. In order to ensure the legality and regularity of the vehicle-mounted equipment, the matching verification password can be configured on the vehicle-mounted equipment. The in-vehicle network can verify or decrypt the matching verification key of the in-vehicle device, and the in-vehicle device that completes the verification or decryption of the matching verification key is recognized as a legal device and can be used in the vehicle. Install the in-vehicle device. see figure 1 , figure 1 A sche...

Abstract

The invention discloses a key configuration system and related methods and products, wherein the method includes: a first server performs qualification verification on vehicle-mounted equipment; if the verification is passed, the first server generates second verification information and sends it to the vehicle-mounted equipment, The second verification information includes a matching verification key corresponding to the in-vehicle device; the in-vehicle device performs authority verification on the second verification information; the matching verification in the second verification information that has passed the authority verification The key is written to the in-vehicle device. In this process, by increasing the participants and verification process of the key setting, the communication security is improved, and the reliability of the key setting is also improved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a key configuration system and related methods and products. Background technique [0002] Autonomous driving is the trend of future car development. Now autonomous driving technology is being vigorously developed and becoming more and more mature. Autonomous vehicles rely on Advanced Driving Assistant System (ADAS) to provide information to make driving decisions, and ADAS includes many sensors, such as cameras, millimeter-wave radar, ultrasonic radar, LiDAR, etc. In addition, the in-vehicle network of a car consists of nearly a hundred on-board computers (Electronic Control Unit, ECU). Obviously, the importance of these in-vehicle devices to vehicle function and driving safety is self-evident. [0003] However, these in-vehicle devices suffer from the following problems. ADAS sensors typically reside outside the vehicle and can therefore be stolen or replaced. Likewis...
